    AI/ML Overview

    The provided text describes the Lenstec LC Injection System, an intraocular lens injection system. However, it does not contain specific acceptance criteria or a study that quantitatively proves the device meets such criteria with detailed metrics like sensitivity, specificity, or accuracy.

    The document generally outlines the device's design, intended use, and substantial equivalence to a predicate device. It mentions "non clinical tests" for biocompatibility and satisfactory testing with specific IOL models, but it does not provide details on the acceptance criteria for "satisfactory" or the performance results.

    Therefore, many of the requested items cannot be extracted from the provided text.

    Here's what can be extracted based on the given text:

    1. Table of acceptance criteria and reported device performance:

      Acceptance CriteriaReported Device Performance
      BiocompatibilitySatisfactory results
      Compatibility with Softec HD IOLSatisfactory results
      Compatibility with Softec I IOLSatisfactory results
      Compatibility with Softec HD PS IOLSatisfactory results

      Note: The document uses "satisfactory results" without defining specific quantitative acceptance criteria or performance metrics.

    2. Sample size used for the test set and the data provenance: Not specified in the document. The text only mentions "All contact materials have been tested for biocompatibility" and "the system was tested with each of the following Lenstec intraocular lens models."

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable/not specified. The testing described appears to be technical performance and biocompatibility testing, not expert-adjudicated clinical data.

    4. Adjudication method for the test set: Not applicable/not specified.

    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: Not applicable. This device is an IOL injection system, not an AI-assisted diagnostic tool.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a medical device, not an algorithm.

    7. The type of ground truth used: For biocompatibility, it would typically be established by standardized laboratory tests (e.g., ISO 10993 series). For IOL compatibility, it would likely be successful injection and proper IOL handling without damage or complications during the process. The document does not specify further details.

    8. The sample size for the training set: Not applicable. This is a physical medical device, not a machine learning model requiring a training set.

    9. How the ground truth for the training set was established: Not applicable.

    Intended Use

    The Lenstec Fluid Isolation Device is intended to hold and seal the lens capsule, to allow irrigation of the capsular bag in an aphakic patient, in order to remove residual cortex and/or epithelial cells

    Device Description

    The Fluid Isolation Device (FID) is a medical device which is intended to hold and seal the lens capsule, to allow irrigation of the capsular bag in an aphakic patient, in order to remove residual cortex and/or epithelial cells. The system consists of the following components: Vacuum ring suction cup connected to lure lock with silicone tubing, 20 mL Vaclok Syringe. Following cataract extraction, the device's vacuum ring suction cup is placed onto the posterior surface of the anterior capsule, and a seal is created by the user drawing back the handle of the Vaclok Syringe. Once the seal is created, the user irrigates the capsule of residual cortex and/or epithelial cells. The device is provided sterile (ethylene oxide).

    AI/ML Overview

    Here's an analysis of the provided text regarding the Lenstec Fluid Isolation Device (FID) and its acceptance criteria, structured as requested:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaReported Device Performance
    BiocompatibilityAll contact materials tested; all results satisfactory and considered equivalent to the predicate device.
    Functional Suction Power over TimePerformance equivalence established using a side-by-side comparison; all results satisfactory and considered equivalent to the predicate device.

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

    The document does not explicitly state a specific "test set" sample size in the context of clinical or in-vivo testing. The performance data presented are from non-clinical bench testing for functional suction power and biocompatibility.

    Data Provenance: The studies were non-clinical (bench tests) and were performed by Lenstec Inc. No country of origin for a clinical test set is relevant here, nor is it retrospective or prospective in the clinical sense.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

    Not applicable. The performance testing was non-clinical (biocompatibility and functional suction power). "Ground truth" in the sense of expert clinical diagnosis or interpretation is not relevant for these types of tests.

    4. Adjudication Method for the Test Set

    Not applicable, as the tests were non-clinical bench tests.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    No. The document explicitly states: "Clinical tests: Not required." Therefore, no MRMC study comparing human readers with or without AI assistance was conducted.

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

    Not applicable. The Fluid Isolation Device (FID) is a medical device, not an AI algorithm. Its performance is directly dependent on user interaction (ophthalmic surgeon drawing back the syringe plunger to create suction).

    7. The Type of Ground Truth Used

    For the non-clinical tests:

    • Biocompatibility: Likely based on standardized assays and comparison to established biological safety limits for medical device materials.
    • Functional Suction Power over Time: Likely based on objective measurements of pressure/vacuum and seal integrity, with "ground truth" being the measurements themselves and the comparison to the predicate device's measured performance.

    8. The Sample Size for the Training Set

    Not applicable. This device is not an AI algorithm, so there is no "training set."

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

    Not applicable, as this device is not an AI algorithm.


    Summary of the Study Proving Device Meets Acceptance Criteria:

    The Lenstec Fluid Isolation Device (FID) was determined to be substantially equivalent to its predicate device, the Milvella Perfect Capsule (K030957), based on non-clinical performance data.

    The studies conducted were:

    • Biocompatibility Testing: All contact materials were tested, and the results were deemed "satisfactory" and "equivalent to the predicate device" (Section 16 of the submission). This addresses the biological safety of the materials used in the device.
    • Functional Suction Power over Time Testing (Bench Test): A "side-by-side comparison" of the FID's functional suction power over time was performed against the predicate device. All results were found to be "satisfactory" and "equivalent to the predicate device" (Section 19 of the submission). This test aimed to demonstrate that the FID could achieve and maintain the necessary seal and suction performance comparable to the legally marketed predicate.

    No clinical studies were required or performed for this 510(k) submission, as the device's technological characteristics and intended use were considered substantially equivalent to a predicate device already on the market. The equivalence was established through material testing and bench performance comparisons.

    Intended Use

    The Lenstec LC Injection System is intended for use in the implantation of STAAR Collamer Intraocular Lens model CC4204BF into the capsular bag following extracapsular extraction.

    Device Description

    The system consists of the following components: Cartridge (LC-16 w/ Silicone Cushion (SIC-01-02) or LC-24 w/ Silicone Cushion (SIC-01-02)) and Injector (I-9011). One type of injector is provided: it is syringe based and is reusable and autoclavable. The cartridges/silicone cushion is single-use and provided sterile.

    AI/ML Overview

    The provided document, K063802, does not include detailed acceptance criteria or a study proving the device meets specific performance metrics in the way that would typically be described for software or AI/ML-based medical devices.

    This device, the Lenstec LC Injection System, is an intraocular lens (IOL) guide and injector system. The submission focuses on demonstrating substantial equivalence to existing predicate devices, a common pathway for Class I and II medical devices that do not involve complex software or AI.

    Here's an analysis based on the document, addressing the prompt's questions where applicable, and noting where information is not present due to the nature of the device and submission:


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

    The document does not specify quantitative acceptance criteria in terms of performance metrics (e.g., accuracy, sensitivity, specificity, or error rates for an AI system). Instead, its "performance data" section is very brief and focuses on:

    • Biocompatibility: "All contact materials have been tested for biocompatibility." This implies meeting regulatory standards for material safety.
    • System Functionality: "The system was tested with STAAR Collamer Intraocular Lens model CC4204BF." This broadly suggests it was confirmed to function with its intended IOL, likely encompassing aspects like smooth delivery and lack of damage to the IOL.

    Given the device type (an injector system), acceptance criteria would likely revolve around mechanical integrity, successful IOL delivery without damage, and material biocompatibility. These are implicitly assumed to be met for substantial equivalence, but explicit metrics are not provided.

    Acceptance Criteria (Inferred from device type)Reported Device Performance
    Materials are biocompatible.All contact materials have been tested for biocompatibility.
    System functions with intended IOL (STAAR Collamer Intraocular Lens model CC4204BF).The system was tested with STAAR Collamer Intraocular Lens model CC4204BF.
    IOL is successfully implanted without damage.(Implicitly assumed through testing with IOL)

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

    • Sample Size: Not specified. The document only states "The system was tested with STAAR Collamer Intraocular Lens model CC4204BF." There is no mention of a specific number of tests or samples.
    • Data Provenance: Not specified. Given the lack of clinical trials, the testing would likely have been bench testing or preclinical, presumably conducted by the manufacturer, Lenstec Inc., based in St. Petersburg, FL, USA.
    • Retrospective or Prospective: Not applicable. The testing described is non-clinical/bench testing, not clinical data collection.

    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)

    Not applicable. This device is an injector system, not a diagnostic or AI device that requires expert-established ground truth for its performance evaluation (e.g., image interpretation). Performance would be assessed through objective measurements during bench testing (e.g., successful ejection, force required, IOL integrity).

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

    Not applicable. There is no expert adjudication process described or required for this type of device's performance evaluation.

    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

    Not applicable. This is not an AI/ML device or a diagnostic device that involves human readers or interpretation.

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

    Not applicable. This is a mechanical device, not an algorithm.

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

    For the "testing" mentioned, the ground truth would likely be objective physical criteria (e.g., visual inspection of IOL for damage, measurement of injection force, successful deployment, material analysis for biocompatibility). These are fundamental engineering and biocompatibility benchmarks, not clinical ground truth in the sense of disease diagnosis or prognosis.

    8. The sample size for the training set

    Not applicable. This is not an AI/ML device that requires a training set.

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

    Not applicable. This is not an AI/ML device that requires a training set.


    Summary regarding the device and approval:

    The K063802 submission for the Lenstec LC Injection System is a 510(k) premarket notification. The core of this submission is to demonstrate substantial equivalence to legally marketed predicate devices, specifically:

    • Lenstec Injection System for Tetraflex Intraocular lenses (K050638)
    • Lenstec Injection System for Softec Injection System (K060533)

    The "study that proves the device meets the acceptance criteria" is implicitly the set of non-clinical tests mentioned (biocompatibility, system testing with the specific IOL). For this class and type of device, substantial equivalence often relies on demonstrating that the new device has the same intended use, similar technological characteristics, and that any differences do not raise new questions of safety or effectiveness compared to the predicate. The FDA concluded that clinical tests were "Not required" for this submission, indicating that the non-clinical data and comparison to predicates were deemed sufficient to establish substantial equivalence.

    The provided document is a 510(k) summary for the Lenstec Injector System for Softec Intraocular Lenses. It does not contain information about acceptance criteria or a study proving the device meets specific acceptance criteria related to its performance metrics as an AI/ML powered medical device.

    Instead, this document focuses on demonstrating substantial equivalence to legally marketed predicate devices, which is a regulatory pathway for certain medical devices in the US. The "performance data" section explicitly states "Non-clinical tests: All contact materials have been tested for biocompatibility. The system was tested with Softec intraocular lenses." and "Clinical tests: Not required."

    Therefore, I cannot fulfill your request for:

    • A table of acceptance criteria and reported device performance.
    • Sample size for the test set or data provenance.
    • Number and qualifications of experts for ground truth.
    • Adjudication method.
    • MRMC comparative effectiveness study results.
    • Standalone performance.
    • Type of ground truth used.
    • Sample size for the training set.
    • How ground truth for the training set was established.

    This document pertains to a physical medical device (an injector system for intraocular lenses) and its regulatory clearance based on substantial equivalence, not an AI/ML powered medical device with performance metrics related to diagnostic accuracy, sensitivity, specificity, etc. The "performance data" refers to biocompatibility and physical compatibility with the lenses, not algorithmic performance.
