The Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, bresbyopia and/or astigmatism) in aphakic and non-aphakic persons with nondiseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lens may be disinfected using a chemical disinfection system only.
The Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lenses are daily wear rigid gas permeable contact lenses:
- in the power range of -20.00 to +20.00 diopters for sphere
- with base curves of 4.0 mm to 11.50 mm
- with base curve chord of 6.0 mm to 6.5 mm
- with diameter of 7.0 to 21.0 mm
The lens material (oprifocon A) incorporates an ultraviolet light absorber and lenses are lathe cut contact lenses in the following designs: spherical, toric, multifocal, and aspheric surfaces in visibility tinted material.
The provided document is a 510(k) Summary for the Acuity 85 (Oprifocon A) Rigid Gas Permeable Contact Lens, which seeks to establish substantial equivalence to a predicate device. As such, it does not detail a study involving AI or human readers, or clinical trials with acceptance criteria for device performance in the way a new medical device would typically be evaluated for accuracy or diagnostic capability.
Instead, the "acceptance criteria" here refers to demonstrating that the new device's material properties and design are substantially equivalent to a legally marketed predicate device, as per FDA guidelines for daily wear contact lenses. The "study" mentioned is primarily non-clinical testing of the material properties.
Here's a breakdown based on the information provided, framed to address your specific questions where applicable, and noting where information is not relevant to this type of submission:
1. Table of Acceptance Criteria and Reported Device Performance
For this 510(k) submission, the "acceptance criteria" are implied by the properties of the predicate device (Boston Equalens II) and the "performance" is the new device's (Acuity 85) equivalent properties. The goal is to show the new device meets or is comparable to the predicate's established properties.
| Characteristic | Acceptance Criteria (Predicate: Boston Equalens II) | Reported Device Performance (Acuity 85) |
|---|---|---|
| Lens Characteristics | ||
| Material | oprifocon A | oprifocon A |
| Production method | Lathe Cut | Lathe Cut |
| UV Blocking | Yes | Yes |
| Base Curves | 4.0 mm to 11.5 mm | 4.0 mm to 11.5 mm |
| Base Curve Chord | 6.0 mm to 6.5 mm | 6.0 mm to 6.5 mm |
| Design | Standard & reverse geometry with anterior aspheric surface | Standard & reverse geometry with anterior aspheric surface |
| Diameters | 7.0-21.0 mm | 7.0-21.0 mm |
| Power Range | -20.00D to +20.00D | -20.00D to +20.00D |
| Astigmatism range corrected | Up to 9.00 D | Up to 9.00 D |
| Add Powers (for multifocal) | +1.00 D to +4.00 D | +1.00 D to +4.00 D |
| Indications for Use | See detailed description in document | See detailed description in document |
| Refractive Index (RGP) | 1.423 | 1.422 ± 0.002 |
| Oxygen Permeability (RGP Center) | 85 | 115 ± 24 |
| Specific Gravity (RGP) | 1.24 | 1.23 ± 0.02 |
| Hardness (Shore D) | 80 | 81 |
| Modulus (MPa) | 1300 | 1378 |
| Tint | Visibility Tints – various | Visibility Tints – various |
| Water Content | <1% | <1% |
| Lens Type | RGP | RGP |
Note: The differences in Refractive Index, Oxygen Permeability, Specific Gravity, Hardness, and Modulus between the new and predicate device are considered acceptable for demonstrating substantial equivalence for this type of device, falling within expected manufacturing variations or improvements that do not raise new questions of safety or effectiveness. For example, a higher oxygen permeability is generally considered an improvement for contact lenses.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This submission relies on non-clinical testing of the lens material. The sample size for material testing is not explicitly stated in the document, but it would typically involve multiple batches or samples of the material to ensure consistency. The provenance is internal to Acuity Polymers, Inc., where the oprifocon A lens material is manufactured. This is laboratory testing, not human subject data, so "retrospective" or "prospective" as applied to clinical studies is not relevant here.
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 type of submission does not involve "experts" establishing ground truth in the context of diagnostic interpretation. The "ground truth" for material properties is established by standardized laboratory testing methods and measurements (e.g., ISO standards or internal validated methods). The document states the material testing meets ISO 10993-1 (2009) for biocompatibility and FDA Daily Wear Contact Lens Guidance Document standards. The staff performing these tests would be qualified laboratory technicians and scientists, but their number and specific qualifications are not detailed in this summary.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Adjudication methods like 2+1 or 3+1 are typically used in clinical studies for resolving discrepancies in expert interpretations of medical images or patient outcomes. This is not relevant to the non-clinical material testing conducted for this 510(k) submission.
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
No MRMC comparative effectiveness study was done, as this submission is for a contact lens material and design, not an AI-powered diagnostic device. The concept of "human readers improve with AI" is not applicable here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No standalone algorithm performance study was done. This device is a physical contact lens, not a software algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" in this context refers to the objectively measured chemical, mechanical, and optical characteristics of the oprifocon A material and the finished lens, obtained through established laboratory testing protocols. These metrics are then compared to the established properties of the predicate device material and design, as well as relevant guidance documents (e.g., FDA Daily Wear Contact Lens Guidance Document, May 1994, and ISO 10993-1 (2009)).
8. The sample size for the training set
This submission did not involve a "training set" in the context of machine learning or deep learning algorithms. It concerns the substantial equivalence of a medical device (contact lens) based on material properties and design.
9. How the ground truth for the training set was established
As there was no training set for an algorithm, this question is not applicable. The "ground truth" for the material characteristics was established through laboratory testing and conformity to existing standards and predicate device properties.

with base curve chord of 6.0 mm to 6.5 mm ●
-
with diameter of 7.0 to 21.0 mm
The lens material (oprifocon A) incorporates an ultraviolet light absorber and lenses are lathe cut contact lenses in the following designs: spherical, toric, multifocal, and aspheric surfaces in visibility tinted material. The material from which these lenses are made and the contact lenses described herein are substantially equivalent to the Boston Equalens II Material and Contact Lenses (oprifocon A) as described in K022128.
{4}------------------------------------------------
These devices will not be marketed with multiple components or any required accessories.
9. Intended Use
The Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lens are indicated for daily wear for the correction of refractive error (myopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D to +20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lens may be disinfected using a chemical disinfection system only.
10. Predicate Devices:
The Acuity 85™ (oprifocon A) RGP contact lenses for daily wear are substantially equivalent to the Boston Equalens II (oprifocon A) Daily Wear Contact Lens (K022128). This lens was selected because it is made from an identical material and has optics designed to address the same Indications for Use.
11. Substantial Equivalence
Substantial equivalence is based on:
For design: The predicate lenses, the Boston Equalens II RGP lenses for daily wear, have a standard or reverse lens geometry with an anterior aspheric optic surface. The new lenses, the Acuity 85™ RGP lenses for daily wear have the same substantially equivalent standard or reverse geometry with an anterior optic surface design.
For material: The predicate lens materials are comprised of a siloxanyl fluoroitaconate copolymer (oprifocon A). The new lens material also is comprised of a siloxanyl fluoroitaconate copolymer (oprifocon A).
The new lenses in this submission therefore are substantially equivalent to the lenses cleared under K022128.
12. Non-Clinical Studies
The oprifocon A lens material manufactured by Acuity Polymers, Inc. has been tested and found to meet the biocompatibility requirements listed in the FDA Daily Wear Contact Lens Guidance Document, May 1994 and ISO 10993-1 (2009) for a surface device, limited contact. The chemical, mechanical and optical characteristics of the new lens have been shown to be equivalent to the predicate lenses.
{5}------------------------------------------------
13. Clinical Studies
Clinical studies for the Acuity 85™ (oprifocon A) material have been deemed as not necessary in support of clearance of this premarket notification as no new or additional questions of safety or effectiveness have been raised as a result of the preclinical testing and evaluation of the material.
14. Packaging
The primary lens container for shipping is a flat pack card. The lenses will not be sterilized by Acuity Polymers, Inc. prior to shipment to customers.
15. Relationship to Special Controls (Guidance)
This submission requires reliance upon a guidance document to describe the change and its relevance to current guidance. The FDA Daily Wear Contact Lens Guidance Document, May 1994, is the relevant document to which this submission is based. Clinical performance data is not necessary since the material and optical design of the new lenses is substantially equivalent to the material and optical design of the predicate lenses in K022128. Both the new lenses and the predicate lens feature identical aspheric anterior optics.

Conclusions
In the evaluation of RGP materials, various properties are measured to ascertain the material's ability to meet the intended application requirements. The properties which characterize the materials classification and use are refractive index, oxygen permeability, specific gravity, hardness, modulus and water content. Those properties are described in the above comparison table. These properties or characteristics are important to the final lens and form the basis for the determination of use. These material values meet the minimum values required for use in the manufacture (lathing) of RGP lenses.
Based on the data generated from the chemical/physical testing (See Side by Side Comparison) of Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lens, it is concluded that the material and contact lens made thereof meet the requirements of a daily wear rigid contact lens and is substantially equivalent to Boston Equalens II (oprifocon A) Daily Wear Contact Lens.
