Device Description

The AQUAIR (enfilcon A) soft contact lens is a Group I, daily wear silicone hydrogel contact lens that is not surface treated and is characterized by a high oxygen permeability (Dk). The lens material, enfilcon A, is composed of silicone macromers cross linked with other monomers, incorporating phthalocyanine blue as an integrated, handling tint. A UV blocker is added to reduce the amount of ultraviolet light transmitted into the eye. The lens will be manufactured in spherical, aspherical, toric and multifocal configurations with the following features and properties:

• Chord Diameter 13.5 mm to 15.0 mm
• Center Thickness 0.05 mm to 0.60 mm
• Base Curve 8.2 mm to 9.2 mm
• Power Range -20.00D to +20.00D in 0.25 steps
• Cylinder Power (Toric) -0.25 to -10.00 D
• Add Power (Multifocal) +0.50 to +4.00 D
• Refractive Index (hydrated) 1.40
• Water Content 46% by weight in normal saline
• Oxygen permeability 100 x 10-11 [(cm²/sec)(ml O₂)/ml*mmHg]], 34°C, Polarographic method (corrected)

The lens is supplied sterile in blister packs containing a buffered saline solution. Labeling is printed with appropriate lot numbering, expiration dating and lens parameter identification. Expiration dating is established based on studies of product stability, package integrity, and sterility.

AI/ML Overview

The CooperVision AQUAIR (enfilcon A) Soft Contact Lens's acceptance criteria and the study proving it meets them are described in the provided document.

1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly define numerical "acceptance criteria" but rather demonstrates substantial equivalence to predicate devices for various physical, optical, chemical, and clinical performance parameters. The table below summarizes these comparative characteristics, with the "Reported Device Performance" for AQUAIR indicating how it compares to the predicate devices.

Characteristic	Predicate Device (BIOFINITY) Performance	Predicate Device (O2 OPTIX™) Performance	AQUAIR (enfilcon A) Reported Performance	Acceptance Criteria (Implicit: Substantial Equivalence to Predicates)
Material	comfilcon A (silicone hydrogel)	lotrafilcon B (silicone hydrogel)	enfilcon A (silicone hydrogel)	Similar material type (silicone hydrogel)
Category (Group)	Group I (low water, nonionic)	Group I (low water, nonionic)	Group I (low water, nonionic)	Same Group Classification
Manufacturing Method	Cast Molded	Cast Molded	Cast Molded	Same manufacturing method
Indication	Daily Wear	Daily Wear	Daily Wear	Same intended wear schedule
Water Content (%)	48	33	46	Within acceptable range for soft contact lenses
Oxygen Permeability - Dk	$128 \times 10^{-11}$	$110 \times 10^{-11}$	$100 \times 10^{-11}$	High oxygen permeability, comparable to silicone hydrogels
Refractive Index	1.40	1.42	1.40	Similar refractive index
Light Transmittance (%)	> 97	> 96	> 97	High light transmittance, comparable to clear lenses
Chord Diameter Range (mm)	13.5 to 15.0	13.0 to 15.0	13.5 to 15.0	Within comparable ranges
Base Curve Range (mm)	8.0 to 9.5	8.0 to 9.2	8.2 to 9.2	Within comparable ranges
Center Thickness (mm)	0.08 @ -3.00D	0.08 @ -3.00D	0.08 @ -3.00D	Similar center thickness
Powers	-20.00D to +20.00D	-1.00 to -6.00D	-20.00D to +20.00D	Broad power range, comparable to full-range lenses
Biocompatibility	(Implicitly passed)	(Implicitly passed)	Passed	No evidence of adverse clinical effects
Visual Acuity Performance	(Historical data)	(Historical data)	No significant difference from predicate	No significant difference
Clinical Adverse Events	(Historical data)	(Historical data)	No significant difference from predicate	No significant difference

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

The document does not explicitly state a numerical sample size for the "test set" in the context of device performance testing. Instead, it refers to "Human Clinical Studies" that compared the AQUAIR lens to historical data of the COOPERVISION BIOFINITY lens. This implies that the 'test set' for clinical performance was the group of participants in the clinical study of AQUAIR.

Sample Size: Not explicitly stated for the clinical study.
Data Provenance: The document does not explicitly state the country of origin. It indicates the study was a "clinical study" and referenced "historical data" for the predicate device, suggesting a prospective study for AQUAIR's clinical evaluation.

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

This information is not provided in the document. The clinical study assessed "visual acuity performance" and "patient complaints or/and slit lamp observations" for safety, but no details are given about the number or qualifications of experts involved in establishing ground truth or evaluating these outcomes.

4. Adjudication Method for the Test Set

This information is not provided in the document.

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

No, an MRMC comparative effectiveness study was not done in the context of comparing human readers' performance with and without AI assistance. This device is a contact lens, and its evaluation focuses on its physical properties, biocompatibility, and direct clinical effects on patients, not on aiding human interpretation of medical images.

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

No, a standalone algorithm-only performance study was not done. This device is a physical contact lens, not an algorithm or AI system.

7. The Type of Ground Truth Used

For the clinical study, the ground truth was established by:

Visual acuity performance: This would be assessed using standard ophthalmic measurements, comparing to the predicate.
Patient complaints: Direct subjective feedback from patients.
Slit lamp observations: Objective clinical observations by practitioners (presumably an optometrist or ophthalmologist) regarding ocular health and adverse events.
These assessments were compared against historical data for the predicate device.

For toxicology studies, the ground truth was based on:

ISO 10993 standards: These provide established benchmarks and methods for assessing cytotoxicity, maximization sensitization, ocular irritation, and systemic toxicity. Animal GLP studies were conducted based on these standards.

8. The Sample Size for the Training Set

This information is not applicable/not provided. The device is a contact lens, not an AI model, so there is no "training set" in the AI sense. The "training" in manufacturing (e.g., initial production runs, quality control) is implicitly covered by standard manufacturing practices, but no specific "training set" data is discussed.

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

This information is not applicable/not provided as there is no "training set" in the context of AI development for this medical device.

8. Physicochemical Studies

The physical, optical and chemical properties of the lenses as assessed by various test methods show substantial equivalency with the predicate devices as illustrated in the preceding table. Additional studies were conducted to verify that leachable substances were either low or below measurable levels to assuage any concerns for its intended use.

9. Toxicology Studies

Animal GLP studies were conducted and determined that AQUAIR (enfilcon A) lenses were biocompatible for the intended use as assessed using ISO 10993 standards for cytotoxicity, maximization sensitization, ocular irritation, and systemic toxicity. All results passed with no evidence of adverse clinical effects caused by the AQUAIR lens.

10. Human Clinical Studies

Clinical studies were conducted to demonstrate substantial equivalence of the AQUAIR (enfilcon A) lens as compared with historical data of the COOPERVISION BIOFINTY lens based on performance and safety. In a study of daily wear, assessment of visual acuity performance showed no significant difference between the two products. Safety as assessed by patient complaints or/and slit lamp observations showed no significant difference of clinical adverse events between the two products. There were no serious or significant adverse events attributable to the device during the study.

11. Conclusions

Based on evaluations of material, manufacturing methods, lens parameters and indicated use, the AQUAR (enfilcon A) lens is substantially equivalent with the predicate, marketed lenses. Based on evaluation of chemical properties, biocompatibility and clinical studies, the AQUAIR (enfilcon A) lens has been shown to be safe and effective for its indicated use.
