It consists of a copolymer of 2-hydroxyethyl methacrylate and N-vinyl pyrrolidinone, and is 70% water by weight when immersed in a sterile saline solution. This lens is tinted blue with either D&C Green #6 or Reactive Blue Dye 246 ((1,4-Bis[4-(2-methacryloxyethyl)phenylamino]anthraquinone). The color additives conform with 21 CFR Part 74.3206 and 21 CFR Part 73.3106, respectively. The lens may also be supplied clear (no tint).

AI/ML Overview

Here's a breakdown of the acceptance criteria and study details for the BAUSCH & LOMB® SofLens™ one day disposable (hilafilcon A) Visibility Tinted Contact Lens, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criterion (Primary Endpoints)Reported Device Performance
Safety: A difference of 10% in the proportions of total grade 2 or greater positive slit lamp findings, between the Test and Control lenses was considered significant.No significant differences were seen between either Test lens modalities (daily and monthly replacement schedule) and the Control lens with respect to physiological response as determined by slit lamp examination. Therefore, the Safety endpoint of the study was achieved.
Efficacy: Test lens is not significantly different from the Control lens in the proportions of lens visual acuities at the level of 20/40 or better.On eye, measured Snellen visual acuity data showed no difference between the Test and Control lenses, attaining the Efficacy endpoint.
Substantial Equivalence to Predicate Device (General)Both the safety and efficacy endpoints were achieved. Almost all differences between the Test and Control lenses for other parameters were attributed to inadequate lens fit due to a lack of base curve choices with the Test lens. The Sponsor concluded substantial equivalence in safety and efficacy.

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

  • Test Set Sample Size: 242 eyes (121 patients).
  • Data Provenance: The document does not explicitly state the country of origin. The study was a "three month clinical study," implying a prospective design.

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

The document does not specify the number of experts used to establish ground truth or their qualifications beyond stating that "10 investigators" participated in the study. These investigators would have performed the slit lamp examinations and visual acuity measurements.

4. Adjudication Method for the Test Set

The document does not describe a specific adjudication method like 2+1 or 3+1. The assessment of safety (slit lamp findings) and efficacy (visual acuity) was likely performed directly by the investigators during patient visits.

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

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This study compared a new medical device (contact lens) to a predicate device, focusing on safety and efficacy in patients, rather than the performance of human readers with or without AI assistance.

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

No, this is a medical device, not an AI algorithm. The concept of "standalone performance" for an algorithm is not applicable here. The study assessed the performance of the contact lens itself when worn by patients.

7. The Type of Ground Truth Used

The ground truth for the clinical study was established through:

  • Clinical Observation/Assessment: Slit lamp examination findings (for safety) and Snellen visual acuity measurements (for efficacy) performed by clinical investigators. This represents a form of expert assessment based on established clinical practices.

8. The Sample Size for the Training Set

This information is not applicable. The study is a clinical trial for a physical medical device (contact lens), not an AI algorithm that requires a training set.

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

This information is not applicable, as there was no AI algorithm with a training set.

The lens is to be prescribed for single-use disposable wear, and is to be discarded after each removal.

DESCRIPTION OF SAFETY AND SUBSTANTIAL EQUIVALENCE 6.

A series of preclinical and clinical testing was performed to demonstrate the safety and effectiveness of the BAUSCH & LOMB SofLens™ one day disposable (hilafilcon A) Contact Lens. A summary of results from the preclinical and clinical tests is provided below.

Preclinical Testing:

A series of in vitro and in vivo preclinical toxicology and biocompatibility testing was performed to assess the safety and effectiveness of the contact lens device. Testing was performed in accordance with FDA guideline titled Premarket Notification (510(k)) Guidance Document for Daily Wear Contact Lenses, May 1994. All non-clinical laboratory studies were conducted in compliance with the GLP regulation.

The results of the preclinical testing on the BAUSCH & LOMB® SofLens™ one day disposable (hilafilcon A) Visibility Tinted Contact Lens demonstrate that:

The physicochemical properties of the BAUSCH & LOMB® SofLens™ (hilafilcon A) one day disposable Visibility Tinted Contact Lens are equivalent to the predicate device, BAUSCH & LOMB® Soft ens66™ (alphafilcon A) Visibility Tinted Contact Lens . The slight differences in the water content of the lens materials accounts for the measured variations in the physicochemical properties between the two lens types.

The extracts of the lens material do not show any significant quantities of monomer components and toxicity testing results of lens extracts and lens material demonstrated no toxicity or irritation.

{3}------------------------------------------------

Clinical Testing:

A three month clinical study was completed to demonstrate that the BAUSCH & LOMB® SofLens™ one day disposable (hilafilcon A) Visibility Tinted Contact Lens (Test) is substantially equivalent in safety and efficacy to the currently marketed BAUSCH & LOMB® SofLens66™ (alphafilcon A) Visibility Tinted Contact Lens (Control), when worn by myopic phakic patients on a daily wear basis. The study was carried out in accordance with the Premarket Notification (510(k)) Guidance Document for Daily Wear Contact Lenses, May 1994.

A total of 242 eyes (121 patients) were entered into the study by 10 investigators. This was a randomized three cell study design. Patients in one cell wore a pair of the Test Lenses with daily replacement schedule (58 patients), patients in the second cell wore a pair of the Test Lenses with monthly replacement schedule (29 patients), while patients in the third cell wore a pair of Control Lenses with no scheduled replacement of lenses (30 patients). Prior to entry into the study, each patient was required to read and sign a Statement of Informed Consent. Study lenses could not be placed on a patient's eye until the Statement of Informed Consent had been completed by the patient and Investigator.

The primary endpoints for this study were:

Safety: A difference of 10% in the proportions of total grade 2 or greater positive slit . lamp findings, between the Test and Control lenses was considered significant.

. Efficacy: Test lens is not significantly different from the Control lens is the proportions of lens visual acuities at the level of 20/40 or better.

There were no significant differences seen between either Test lens modalities (daily and monthly replacement schedule) and the Control lens with respect to physiological response as determined by slit lamp examination. Therefore, the Safety endpoint of the study was achieved.

On eye, measured Snellen visual acuity data showed no difference between the Test and Control lenses, attaining the Efficacy endpoint.

Both the safety and efficacy endpoints, as defined in the study protocol, were achieved, and almost all differences between the Test and Control lenses, for other parameters can be attributed to inadequate lens fit, due to a lack of base curve choices with the Test lens. Based on these data, the Sponsor concludes that the Test lens, is substantially equivalent in both safety and efficacy to the Control lens, when used on a daily wear basis, for both daily and monthly replacement schedules.

{4}------------------------------------------------

Substantial Equivalence

The BAUSCH & LOMB® SofLens™ one day disposable (hilafilcon A) Visibility Tinted Contact Lens is similar to the BAUSCH & LOMB® SofLens66™ (alphafilcon A) Visibility Tinted Contact Lens, in that both fall into the same FDA material classification grouping (Group II) and both are manufactured by the same manufacturing process (cast molding). The BAUSCH & LOMB® Soft ens™ one day disposable (hilafilcon A) Visibility Tinted Contact Lens is different from the BAUSCH & LOMB® SofLens66™ (alphafilcon A) Visibility Tinted Contact Lens in that it has a different USAN name (hilafilcon A vs. alphafilcon A). The differences between these two lenses will not have any negative effect on the safety and effectiveness of the device.

All product will be sold as sterile medical devices.
