The LenSx Laser system is indicated for use:

• In the creation of corneal cuts/incisions (single-plane, multi-plane, and arcuate), anterior capsulotomy and laser phacofragmentation during cataract surgery. Each of these procedures may be performed either individually or consecutively during the same surgery.
• In the creation of corneal cuts/incisions (single-plane, multi-plane, and arcuate) during Implantable Collamer Lens (ICL) surgery.
• In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea.
• In the creation of corneal pockets for placement/insertion of a corneal inlay device; and for creation of corneal tunnels for the placement of corneal rings.

The LenSx Laser system is an ophthalmic surgical laser which uses focused femtosecond laser pulses to create vapor bubbles which disrupts/separates tissue (photodisruption) within the lens capsule, crystalline lens, and the cornea. A computer-guided delivery system places the laser pulses in a pattern to produce an incision/cut.

The laser pulses are delivered through a sterile, disposable applanating lens and suction ring that contacts the cornea and fixes the eye with respect to the laser delivery system.

The interface between the laser and patient is the Patient Interface that connects to the delivery system which is docked to the patient's cornea. Two models of the Patient Interface accessory are offered for use with the LenSx Laser: the LenSx Laser Patient Interface and the LenSx Laser SoftFit Patient Interface. Both models consist of a sterile, disposable applanating lens and suction ring assembly. The LenSx Laser SoftFit Patient Interface also comes with a soft contact lens that is positioned against the external surface of the Patient Interface glass. For cataract procedures, the LenSx Laser SoftFit Patient Interface is used. The LenSx Laser Patient Interface is used for corneal, flap, tunnel, and pocket incisions. Refer to the Instructions for Use supplied with the LenSx Laser Patient Interface for preparation and application.

The LenSx Laser system is for prescription use and should only be operated by a trained physician. The LenSx Laser system is intended to be used within a clinic(s)/hospital(s)/surgical practice network.

Based on the provided FDA 510(k) Clearance Letter for the LenSx Laser System, this document primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with detailed acceptance criteria and performance data for a new AI or novel diagnostic device.

The clearance is for a modified version of an existing device (LenSx Laser System) with software updates and an expanded indication for Implantable Collamer Lens (ICL) surgery. The general approach taken is to show that these modifications do not raise new questions of safety or efficacy and that the device remains substantially equivalent to its predicate. Therefore, the requested information regarding acceptance criteria and a study proving the device meets those criteria (especially in the context of an AI/diagnostic device) is not explicitly detailed in this 510(k) summary.

However, I can extract the relevant information presented, acknowledging that it's framed within the context of demonstrating substantial equivalence for a modified device, rather than a de novo clearance for a completely new technology with novel performance claims.

Here's an attempt to answer the questions based on the provided text, highlighting where the information is not applicable or not detailed in this type of submission:

Acceptance Criteria and Device Performance Study (as inferred from the 510(k) Summary)

The 510(k) summary indicates that the modifications to the LenSx Laser System are minor and do not introduce new safety or efficacy concerns. The "acceptance criteria" are implied by the successful completion of various non-clinical tests demonstrating that the device continues to meet its intended design specifications and functional requirements, performing as intended and being equivalent to the predicate. There are no specific numerical performance metrics provided in the summary that would typically be seen for a new diagnostic or AI device (e.g., sensitivity, specificity, accuracy against a gold standard).

Table of Acceptance Criteria and Reported Device Performance

Since this is a modification to an existing device, the "acceptance criteria" are generally about maintaining the performance and safety profiles of the predicate. The "reported device performance" refers to the successful completion of the tests.

Study Details (as applicable)

1. Sample sizes used for the test set and the data provenance:

   • Test Set Sample Size: Not specified in terms of clinical cases or patient data, as no animal or clinical testing was deemed necessary for this submission. The "test set" primarily refers to bench testing, software verification/validation, and regulatory compliance checks.
   • Data Provenance: Not applicable as no clinical or animal data was collected for this submission. The data provenance for compliance testing is internal Alcon laboratories.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

   • Not applicable as this 510(k) submission does not rely on expert-adjudicated ground truth from a clinical test set. The ground truth for engineering and software tests is based on design specifications, recognized standards, and regulatory guidance. For clinical ground truth, the submission relies on the established safety and efficacy of the predicate device and the assessment that the modifications do not alter this.

3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

   • Not applicable. There was no clinical test set requiring expert adjudication.

4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • No MRMC study was performed or required. The device is a surgical laser, not an AI-assisted diagnostic tool that would typically involve human readers.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

   • Not applicable in the context of an AI algorithm. However, the device itself, including its software, undergoes standalone functional and safety testing as part of the "Non-Clinical Testing" detailed in Section 7.1, such as "Software verification and validation testing" and "Performance Testing." These tests ensure the device (algorithm and hardware) performs its functions correctly according to specifications, independent of operator interaction after initial surgical planning.

6. The type of ground truth used (expert concensus, pathology, outcomes data, etc):

   • For the non-clinical and software testing, the "ground truth" is defined by:
     • Engineering Specifications: The pre-defined technical and functional requirements for the laser system.
     • International and National Standards: Compliance with standards like IEC 60601 series, ANSI Z80.36-2021 for safety and performance.
     • FDA Guidance Documents: Compliance with FDA recommendations for software documentation and cybersecurity.
     • Predicate Device Performance: The established safety and effectiveness of the existing LenSx Laser System serves as the clinical benchmark.

7. The sample size for the training set:

   • Not applicable. This is not an AI/machine learning device that relies on a "training set" of data in the typical sense for a new diagnostic algorithm. The software modifications are deterministic or rule-based enhancements (e.g., embedded calculator, new cut patterns).

8. How the ground truth for the training set was established:

   • Not applicable for the same reason as above. If there were internal development/optimization processes for the new features (e.g., nomogram calculations), their accuracy and "ground truth" would be established through mathematical validation, simulation, and bench testing against known physical principles or desired outcomes, rather than a data-driven training set.

Dailies Total 1 (delefilcon A) soft contact lenses are available in spherical, toric (for astigmatism) and multifocal toric lens designs.

I am sorry, but the provided text does not contain information about the acceptance criteria for a device, nor does it describe a study that proves a device meets such criteria.

The document is an FDA 510(k) clearance letter for Alcon's contact lenses (Precision1 and Dailies Total1 families). It primarily discusses:

• The FDA's determination of substantial equivalence to predicate devices.
• The general controls and regulations applicable to the devices.
• The indications for use for the various contact lens products.
• A summary of the device description and intended use.
• A statement that the submission is for a manufacturing change (modification of extraction and coating processes) and that no clinical testing was required to establish safety and effectiveness for this specific change. Instead, non-clinical bench testing demonstrated that the lenses meet established finished product specifications and are substantially equivalent to the predicate devices.

Therefore, I cannot fulfill your request as there is no information in the provided text regarding:

1. A table of acceptance criteria and reported device performance.
2. Sample sizes for a test set or data provenance.
3. Number and qualifications of experts for ground truth establishment.
4. Adjudication methods.

6. Standalone algorithm performance.
7. Type of ground truth used (expert consensus, pathology, outcomes data, etc.).
8. Sample size for a training set.
9. How ground truth for a training set was established.

These elements are typically found in documents describing clinical trials, performance studies for AI/ML-driven devices, or detailed design verification and validation reports, none of which are present in this FDA 510(k) clearance letter.

Alcon 27GA Chandelier
The 27GA Chandelier is indicated for use during posterior segment ophthalmic surgery.

Alcon 27+ DS Wide Angle Endoilluminator
The 27+DS Wide-Angle Endoilluminator is indicated for use during posterior segment ophthalmic surgery.

Alcon 27+ DS Endoilluminator
The 27 + DS Endoilluminator is indicated for use during posterior segment ophthalmic surgery.

As part of this premarket notification Alcon presents three new endoilluminators, compatible with the UNITY VCS device cleared in K233876 (clearance date: June 21, 2024).

Alcon 27GA Chandelier: The Alcon 27GA Chandelier provides a hands-free wide field of illumination for vitreoretinal procedures. The distal end of the device incorporates a short, tapered fiber optic to provide wide angle illumination projected from a pars plana position of the eye. The distal end consists of a tapered fiber, which is inserted into the eye through the Alcon 27GA entry system. The fiber is malleable so the physician can shape it to form a stable service loop, position the tip, and minimize interference with the lid speculum.

Alcon 27+ DS Wide Angle Endoilluminator: The Alcon 27+ DS WA Endoilluminator offers wide-angle illumination, featuring a sapphire lens at the distal end of the probe. This design ensures consistent, low-glare illumination across a broad field of view. Additionally, it incorporates a Dynamic Stiffener (DS) element-a retractable stiffener designed to minimize needle deflection at the proximal end of the stainless steel cannula. as opposed to the fixed stiffener used in previous models.

Alcon 27+ DS Endoilluminator: The Alcon 27+ DS Endoilluminator transmits light energy into the eye and incorporates a DS element at the proximal end of the stainless-steel cannula.

This FDA 510(k) summary does not contain the specific acceptance criteria or performance data in a format that directly matches the requested table. This document is a "Substantial Equivalence" submission, which focuses on demonstrating that new devices (Alcon 27GA Chandelier, Alcon 27+ DS Wide Angle Endoilluminator, Alcon 27+ DS Endoilluminator) are as safe and effective as previously cleared predicate devices, rather than establishing specific performance metrics against pre-defined acceptance criteria for a novel device.

The document primarily relies on non-clinical testing to demonstrate substantial equivalence. Here's a breakdown of the information available:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not provide a table of acceptance criteria with corresponding performance results in a quantitative manner for specific clinical metrics. Instead, it states that the devices "met ISO 10993" for biocompatibility, "passed the predetermined acceptance criteria" for sterilization and shelf life, and that "safety tests demonstrated the compliance of the subject devices to the appropriate standards" for performance testing. For light hazard testing, it states the devices "meet aphakic and thermal safety standards comparable to the predicate devices."

The comparisons in Tables 1-3 highlight similarities in technological characteristics between the subject devices and their predicates, rather than presenting numeric acceptance criteria.

2. Sample Size Used for the Test Set and Data Provenance:

• Non-Clinical Testing: The document refers to "tested devices" for sterilization, "tested units" for packaging integrity, and "three subject devices" for light hazard testing. However, specific sample sizes (e.g., number of units tested for biocompatibility, number of sterilization cycles validated) are not provided.
• Data Provenance: All testing described is non-clinical. There is no mention of human subject data, therefore no information on country of origin or retrospective/prospective nature.

3. Number of Experts Used to Establish Ground Truth and Qualifications:

Not applicable, as this submission concerns non-clinical testing of medical devices (endoilluminators and a chandelier) for surgical use, not AI/diagnostic devices requiring expert adjudication for ground truth.

4. Adjudication Method for the Test Set:

Not applicable, as this submission concerns non-clinical testing of medical devices (endoilluminators and a chandelier), not AI/diagnostic devices requiring adjudication.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done:

No, an MRMC comparative effectiveness study was not done. This submission is for physical medical devices, not AI software where such studies are typically performed.

6. If a Standalone Performance (Algorithm Only Without Human-in-the-Loop Performance) was Done:

Not applicable. This is not an AI device. The "performance testing" referenced is for the physical attributes and safety of the endoilluminators (e.g., light transmission, mechanical integrity, biocompatibility), which are inherently "standalone" in their assessment as device components.

7. The Type of Ground Truth Used:

For the non-clinical tests, the "ground truth" is defined by:

• Biocompatibility: ISO 10993 standards.
• Sterilization: ISO 11135 and ISO 10993-7 standards; achieving a Sterility Assurance Level (SAL) of 10⁻⁶.
• Shelf Life/Packaging: ASTM D4169, ASTM F1980, and ISO 11607-1 standards.
• Performance (General): ISO 14971, ISO 15004-1, ISO 15752, and ANSI Z80.36 standards.
• Light Hazard: ANSI Z80.36 and ISO 15752 standards, and comparability to predicate devices.

8. The Sample Size for the Training Set:

Not applicable. This is not an AI/machine learning device; therefore, there is no training set in the AI sense.

9. How the Ground Truth for the Training Set Was Established:

Not applicable. There is no training set.

Summary of Device Acceptance:

The acceptance of these devices is based on demonstrating substantial equivalence to existing predicate devices (cleared under K875005 and K110951) through a battery of non-clinical tests. The tests confirm they meet established safety and performance standards (ISO, ASTM, ANSI) and have comparable technological characteristics and risk profiles to their predicates, making them safe and effective for their intended use in posterior segment ophthalmic surgery.

This document is a 510(k) Premarket Notification from the FDA regarding Alcon Laboratories' DAILIES TOTAL1® contact lenses. It addresses the substantial equivalence of modifications to the existing device.

Here's an analysis to extract the requested information regarding acceptance criteria and the study proving the device meets them:

Important Note: This FDA document approves modifications to an existing contact lens. Therefore, the "acceptance criteria" and "study" described here are primarily focused on demonstrating that the modified device remains substantially equivalent to the predicate device, rather than proving a new device's initial safety and effectiveness from scratch. This distinction is crucial for interpreting the provided information.

1. A table of acceptance criteria and the reported device performance

Based on the document, the acceptance criteria are not presented in a formal table with specific numerical targets. Instead, the document states that the performance testing aimed to demonstrate "substantial equivalence" to the predicate device. The reported device performance is described qualitatively as "demonstrated to be substantially equivalent" and "all with passing results."

Here's a breakdown of the areas tested and the general "performance":

• Refractive Index (hydrated): 1.42
• Light Transmittance: ≥ 93% (@ 610 nm, -1.00 D)
• Oxygen Permeability: 140 barrer
• Water Content: 33% by weight in normal saline" |
  | Dimensional & Optical Properties | Substantially equivalent to predicate device (maintaining appropriate ranges for diameter, base curve, power, center thickness, cylinder, ADD). | "Lens material properties, dimensional and optical properties, and extractables and residuals were demonstrated to be substantially equivalent to the predicate device."

2. Sample sizes used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

The document does not explicitly state numerical sample sizes for any of the non-clinical tests (e.g., number of lenses tested for material properties, number of animals in biocompatibility studies). It only mentions that testing was conducted "using GxP conditions," referring to good x practice (e.g., Good Manufacturing Practices, Good Laboratory Practices).

The data provenance (country of origin, retrospective/prospective) is also not specified. Given the regulatory nature and the mention of GLP for biocompatibility, these studies would have been prospective and conducted according to relevant international standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

This information is not applicable or not provided in this document.

• No expert ground truth for classification/diagnosis: The testing described is primarily physical, chemical, and biological (biocompatibility) in nature for a medical device (contact lens). There is no "ground truth" in the sense of expert human interpretation of medical images or patient conditions, as would be the case for an AI diagnostic device.
• Standards-based evaluation: The "ground truth" for these tests comes from established industry standards (e.g., ISO for contact lenses, ISO 10993 for biocompatibility) and regulatory guidelines (e.g., FDA 510(k) Guidance for Class II Contact Lenses). The "experts" involved would be the testing laboratories' personnel with expertise in these specific tests and their interpretation according to the standards. Their specific qualifications and numbers are not detailed here.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This information is not applicable or not provided. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or human-in-the-loop performance evaluations for diagnostic devices where human experts disagree on interpretations. Here, the testing is non-clinical/laboratory-based against pre-defined physical, chemical, and biological criteria and established standards.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This information is not applicable. This document is for a contact lens, not an AI diagnostic device. Therefore, no MRMC study or AI assistance evaluation was performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable. This document is for a contact lens; there is no algorithm or AI involved. The "device performance" refers to the physical, chemical, and biological properties of the contact lens itself.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the non-clinical testing of this contact lens is based on:

• Established industry standards: Primarily ISO 18369-2, -3, -4 for contact lenses and ISO 10993 series for biocompatibility.
• FDA guidance documents: Specifically the May 1994 FDA guideline titled "Premarket Notification 510(k) Guidance Document for Class II Contact Lens testing."
• Prior device specifications: The modified device is compared to the predicate device to demonstrate substantial equivalence across various properties.
• GLP (Good Laboratory Practices) requirements: For biocompatibility testing (21 CFR Part 58).

So, the ground truth is standards-based and regulatory-guidance driven, ensuring the device meets pre-defined safety and performance thresholds for physical, chemical, and biological attributes, and remains equivalent to a previously cleared device.

8. The sample size for the training set

This information is not applicable. This is a physical medical device (contact lens), not a machine learning/AI model. Therefore, there is no "training set."

9. How the ground truth for the training set was established

This information is not applicable as there is no training set for this type of device.

The lenses are to be prescribed for single use, as recommended by the eye care professional. The lenses are not intended to be cleaned or disinfected and should be discarded after a single use.

Precision1 (verofilcon A) soft contact lenses are currently available in a spherical and a toric lens design.
Precision1 (verofilcon A) spherical soft contact lenses are indicated for the optical correction of refractive ametropia (myopia and hyperopia) in phakic persons with non-diseased eyes and approximately 1.50 diopters of astigmatism that does not interfere with visual acuity.
Precision1 for Astigmatism (verofilcon A) toric soft contact lenses are indicated for the optical correction of refractive ametropia (myopia and hyperopia) in phakic persons with nondiseased eyes and 6.00 diopters (D) or less of astigmatism.
Precision 1 (verofilcon A) soft contact lenses are supplied sterile, immersed in buffered saline solution and packaged in individual foilblister packs, which are terminally sterilized in a validated autoclave (moist heat, steam under pressure). The foil-blister pack system consists of a polypropylene (PP) blister shell sealed with a coated aluminum foil lidding. The blister packaged into carton boxes available in different pack sizes.

This document describes the 510(k) premarket notification for the Precision1 and Precision1 for Astigmatism soft contact lenses. The submission is for a modification to an already legally marketed predicate device (Precision1 for Astigmatism, K182902). The modification involves adding foil from an alternate supplier for primary packaging and extending the product expiration dating from 72 to 84 months.

The document states that the scope of the device modification did not require clinical testing to establish safety and effectiveness. Therefore, the information typically associated with studies proving device performance against acceptance criteria (such as sample sizes, ground truth establishment, expert adjudication, or MRMC studies) is not present in this document. The device stability and process validation were completed to verify equivalence to the predicate device.

Here's the information that could be extracted from the document regarding acceptance criteria and the study, as much as applicable:

1. A table of acceptance criteria and the reported device performance

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document as part of a clinical study. The document refers to "stability testing" and "process validation," which are typically laboratory-based tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable as the document states that clinical testing was not required for this submission. The "ground truth" for the non-clinical tests would be defined by pre-established scientific and engineering standards for stability and process validation, not by human expert consensus or clinical outcomes.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable as there was no clinical test set requiring expert adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

There was no MRMC comparative effectiveness study done. This submission is for a material and shelf-life extension change to an existing contact lens, not an AI-powered diagnostic device.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

This information is not applicable as this device is a contact lens, not an algorithm or AI.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the non-clinical "stability testing" and "process validation," the ground truth would be established by scientific and engineering specifications and standards for contact lens materials, sterility, and performance over time. This is not medical expert consensus, pathology, or outcomes data.

8. The sample size for the training set

This information is not applicable as there was no training set for an algorithm or AI.

9. How the ground truth for the training set was established

This information is not applicable as there was no training set for an algorithm or AI.

AIR OPTIX® COLORS (lotrafilcon B) spherical soft contact lenses with refractive power are indicated for daily wear for the optical correction of refractive ametropia (myopia) in phakic or aphakic persons with non-diseased eyes and up to approximately 1.50 diopters of astigmatism that does not interfere with visual acuity.

AIR OPTIX® COLORS (lotrafilcon B) toric soft contact lenses are indicated for daily wear for the optical correction of refractive ametropia (myopia and hyperopia) in phakic persons with non-diseased eyes with 6.00 diopters (D) or less of astigmatism.

AIR OPTIX® COLORS (lotrafilcon B) multifocal soft contact lenses are indicated for daily wear for the optical correction of presbyopia with or without refractive ametropia) in phakic or aphakic or aphakic persons with non-diseased eyes who may require a reading addition of +3.00 diopters (D) or less and who may have up to approximately 1.50 diopters of astigmatism.

AIR OPTIX® COLORS (lotrafilcon B) lenses with or without refractive power act to enhance or alter the apparent color of the eye.

The lenses may be prescribed for frequent/planned replacement wear with daily removal for cleaning and disinfection (chemical, not heat) prior to reinsertion, as recommended by the eye care professional.

The lens material of AIR OPTIX® COLORS is 33% water and 67% lotrafilcon B, a fluorosilicone containing hydrogel which is surface treated. Lotrafilcon B is classified as a Group 5 (silicone hydrogel) hydrogel contact lens material according to ISO 18369-1:2017. A cosmetic pattern is embedded into the back surface of the lens, containing a combination of the following color additives: carbazole violet, iron oxides, [phthalocyaninato (2-)] copper, phthalocyanine green and titanium dioxide.

Cleared lens designs for AIR OPTIX® COLORS (lotrafilcon B) include spherical, toric, and multifocal lenses in the following parameter range:
• Diameter Range: 13.0 to 15.0 mm
• Base Curve Range: 8.0 to 9.2 mm
• Power Range: -20.00 D to +20.00 D
• Center Thickness: varies with design and power (0.08 mm for -3.00 D spherical)

Lenses have the following properties:
• Refractive index: 1.42 (hydrated)
• Luminous transmittance: 95 ± 5%
• Water content: 33% by weight in normal saline
• Oxygen permeability: 110 x 10-11 (cm²/sec)(ml O₂ /ml x mm Hg), measured at 35 °C (intrinsic Dk – Coulometric method)

Lenses are supplied sterile in sealed blister packs containing phosphate buffered saline solution (PBS) with 1% Copolymer 845 (labeled as buffered saline containing 0.2% VP/DMAEMA Copolymer). The compatibility and package integrity of the blister pack packaging system has been demonstrated and successfully used for other marketed lens products, and packaged lenses are effectively steam sterilized in a validated autoclave. Blister pack containers are labeled with the lens parameters, lens color, lot number and product expiration date. The expiration date has been established through stability studies that have assessed the chemical stability of the lens and package integrity (ability to maintain sterility). Shelf-life studies are ongoing to further extend the labeled expiration date.

The provided text describes a 510(k) premarket notification for a medical device, specifically AIR OPTIX® COLORS (lotrafilcon B) Soft Contact Lenses, and a modification to its primary packaging. It details the device, its intended use, and a comparison to a predicate device. However, it does not include detailed acceptance criteria or a study proving the device meets performance criteria in the way typically expected for an AI/ML medical device.

The context of the document is a regulatory submission for a contact lens and a packaging change, not a software or AI device. Therefore, the specific information requested in the prompt related to AI/ML device evaluation (e.g., test set sample size, ground truth establishment, MRMC study, effect size, training set) is not applicable or present in this document.

Instead, the document focuses on demonstrating substantial equivalence to a predicate device for a physical medical product and a packaging modification. The "Performance Data" section primarily addresses non-clinical testing to verify equivalence for the packaging change, rather than performance of the contact lens itself (which was previously established for the predicate).

Here's a breakdown of the relevant information provided, adapted to the context of the document:

1. A table of acceptance criteria and the reported device performance

The document doesn't present a formal table of acceptance criteria and performance for the device itself (the contact lens) because the 510(k) is primarily for a packaging modification. Instead, it states that "Testing resulted in all acceptance criteria being met" for the packaging modification.

Acceptance Criteria and Reported Device Performance (Related to Packaging Modification)

Study Proving Device (Packaging Modification) Meets Acceptance Criteria

The study described is a non-clinical evaluation to demonstrate that the modified packaging (alternate foil lidding material from "Constantia-Pirk") does not negatively impact the safety and performance of the AIR OPTIX® COLORS contact lenses.

2. Sample sized used for the test set and the data provenance

• Sample Size: Not explicitly stated. The document mentions "representative lotrafilcon B soft contact lenses" were used for stability, biocompatibility, and process validation testing, but does not provide specific numbers.
• Data Provenance: Not explicitly stated, but it would be from internal Alcon Laboratories, Inc. testing facilities or contracted laboratories for the specific non-clinical tests conducted. The testing is reported as "successful," implying it was conducted as part of the regulatory submission process.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This is not applicable as the submission is for a physical medical device (contact lens) and a packaging change, not an AI/ML device requiring expert ground truth for image interpretation or diagnosis. The evaluation relied on scientific and engineering testing for stability, biocompatibility, and process validation.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This is not applicable for a contact lens packaging modification. Adjudication methods are typically used in clinical studies involving interpretation of data by multiple experts, which is not the nature of this submission. The "adjudication" here would be the scientific review and approval of the test results by qualified personnel within Alcon and subsequently by the FDA.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable as the device is a contact lens, not an AI-assisted diagnostic tool. No human readers or AI assistance are involved in the performance evaluation described.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This is not applicable as the device is a contact lens, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The concept of "ground truth" as typically applied to AI/ML devices is not applicable here. For this submission, the "truth" is established by adherence to validated scientific and engineering testing methods for characteristics like material stability, sterility, and biocompatibility, as outlined in relevant standards and guidelines (e.g., FDA guidance for contact lenses, ISO standards).

8. The sample size for the training set

This is not applicable as the device is a contact lens and not an AI/ML model that requires a training set.

9. How the ground truth for the training set was established

This is not applicable as the device is a contact lens and not an AI/ML model.

The lenses are to be prescribed for daily wear with removal for disposal, or cleaning and heat) prior to reinsertion, as recommended by the eye care professional. Lenses should be discarded with a new pair each week, or more often, if recommended by the eye care professional.

The subject device is made from a silicone containing hydrogel lens material that is approximately 55% water and 45% serafilcon A. The color additive Reactive Blue 247 is added to the lens material to create a light blue-green edge-to-edge color to make it easier to see when handling. In addition, lenses contain two benzotriazole monomers to block UVA and UVB radiation, and additionally, reduce transmittance in the range of 380 nm to 450 nm.

Serafilcon A represents a Group 5B silicone hydrogel contact lens material ('enhanced oxygen permeable materials') according to ISO 18369-1:2017, Ophthalmic optics - Contact lenses - Part 1: Vocabulary, classification system and recommendations for labelling specifications.

Serafilcon A lens designs include spherical, toric, multifocal toric lenses in the following parameter ranges:

• Diameter Range: 13.0 to 15.0 mm
• Base Curve Range: 8.0 to 9.2 mm
• Power Range: -20.00 D to +20.00 D
• Center Thickness: varies with design and power (Example: 0.08 mm for -3.00 D spherical)
• Cylinder Power (toric) Range: -0.25 D to -10.00 D
• Cylinder Axis (toric) Range: 001 to 180°
• ADD Power (multifocal) Range: LO, MED, HI

Lenses have the following properties:

• Refractive index: 1.40 (hydrated)
• Water content : 55% by weight in normal saline
• Oxygen permeability: 119 x 10 -11 [(cm2 /sec)(ml O2 /mlommHg)] measured at 35 °C (normalized Dk-Polarographic method)
• Light transmittance: ≥85%
• UV Transmittance: The transmittance characteristics are less than 1% in the UVB range of 280 nm to 315 nm and less than 10% in the UVA range of 316 to 380 nm for the entire power range.

Serafilcon A contact lenses are supplied sterile in sealed blister packs containing isotonic phosphate buffered saline solution (PBS) with polymeric wetting agents.

The provided text describes the Alcon™ contact lenses and their substantial equivalence to a predicate device, CooperVision Biofinity (comfilcon A) soft contact lens. However, the text details the testing performed to demonstrate safety and performance for the contact lenses themselves, not the acceptance criteria and performance of an "AI/algorithm device" as implied by the structure of the request.

Therefore, I cannot extract the information required for the requested table and study details (sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC study details, standalone performance, type of ground truth, training set size, and training ground truth establishment) because the document does not concern an AI/algorithm device.

The document discusses the following:

• Device Name: Alcon™, Alcon™ for Astigmatism, Alcon™ Multifocal, Alcon™ Multifocal Toric (serafilcon A) soft contact lenses
• Predicate Device: CooperVision Biofinity (comfilcon A) soft contact lens
• Performance Data: A series of nonclinical tests (biocompatibility, physical-chemical, solution compatibility, sterilization, and stability) and a clinical study were performed to demonstrate substantial equivalence.
• Clinical Study Details:
  • Design: Prospective, randomized, stratified, controlled, double-masked, parallel group study.
  • Study Sites: Eight (8) sites in the US.
  • Subjects Enrolled: 120 subjects (240 eyes), with 119 randomized and exposed, and 110 completing the study.
  • Ratio: 2:1 ratio of test (serafilcon A, 78 subjects) to control (comfilcon A, 41 subjects).
  • Wear Modality: Daily wear for approximately 3 months.
  • Replacement Schedule: Test lenses replaced weekly, control lenses monthly.
  • Primary Effectiveness Endpoint: Study lens visual acuity at distance.
  • Other Assessments: Refraction, keratometry, lens fit, surface characteristics, subjective ratings of vision, comfort, and handling.
  • Conclusion: The study showed similar clinical performance between test and control lenses in vision, comfort, fit, handling, and health, demonstrating substantial equivalence.

Since the request is specifically for an algorithm/AI device, and the provided text is about contact lenses, I am unable to fulfill the request as stated.
