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

The document provides information on clinical studies but does not explicitly define a "test set" in the context of an algorithm's performance evaluation as might be expected for an AI device. Instead, it describes clinical trials.

Clinical Studies (Safety and Efficacy):
- One three-month clinical study with asymptomatic soft (hydrophilic) lens wearers.
- One one-month study with silicone hydrogel lens wearers.
- One one-month study with symptomatic soft (hydrophilic) lens wearers.
- An additional clinical study for wettability evaluation (also cited in wettability studies section).
Sample Size: The exact number of subjects in each clinical study is not provided.
Data Provenance: The document does not specify the country of origin for the clinical study data or explicitly state whether they were retrospective or prospective. Given they are described as "clinical studies" and compare "regimens," they are inherently prospective.

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

This information is not provided in the document. The studies described are clinical trials evaluating the product's performance in human subjects, not a diagnostic algorithm where expert consensus might establish a "ground truth" for a specific condition. Evaluations would likely be conducted by optometrists or ophthalmologists, but their number and specific qualifications are not detailed.

4. Adjudication Method for the Test Set

This information is not provided. As detailed above, the context is not an algorithm performance evaluation where expert adjudication of results would be typical. Clinical trial outcomes would be assessed based on established clinical endpoints and measurements.

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 Multi-Reader Multi-Case (MRMC) Study was done. The device is a contact lens care solution, not an AI-powered diagnostic tool.
No AI assistance is involved. Therefore, there is no effect size related to human reader improvement with or without AI.

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

No standalone algorithm performance was done. The device is a physical product (contact lens solution), not an algorithm.

7. The Type of Ground Truth Used

For this type of device (contact lens solution):

Clinical Ground Truth: Clinical studies assessed various parameters like comfort levels, lens deposits, corneal staining, and wettability. These are direct measurements of physiological responses or visual assessments made by clinicians.
Microbiological Ground Truth: For efficacy, laboratory standards (e.g., FDA Guidance, EN ISO 14729) define target log reductions for specific microorganisms, which serve as the "ground truth" for antimicrobial activity.
Chemical/Physical Ground Truth: Cleaning efficacy (CMC), compatibility, and wettability studies use scientific measurements and established physical/chemical principles.

8. The Sample Size for the Training Set

Not applicable. The device is a contact lens solution, not an AI model. Therefore, there is no "training set." The product's formulation and associated laboratory testing could be considered its developmental "training," but not in the context of machine learning.

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

Not applicable. As there is no training set for an AI model, this question does not apply. The "ground truth" for the product's development and pre-clinical testing would be established through established scientific methods, chemical analysis, in vitro microbiological assays, and compatibility testing with known lens materials.

Compatibility Studies

Lens compatibility studies performed with silicone hydrogel and FDA Groups I and IV contact lenses show that ALCON® Multi-Purpose Disinfecting Solution is compatible with all soft contact lenses including silicone hydrogels.

Wettability Studies

In vitro and ex vivo wettability studies were carried out on ALCON® Multi-Purpose Disinfecting Solution versus Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution marketed disinfection product. The in vitro study results correlated with the ex vivo study data where the ALCON® Multi-Purpose Disinfecting Solution formulation showed significantly lower wetting angles indicating excellent wettability. Comparatively, the Bausch & Lomb ReNu Multi-Purpose Solution product showed high contact angles in the plateau region of the in vitro wetting data and this correlated with the ex vivo data where high wetting angles were observed. All of the ex vivo wetting angles were observed after eight hours of contact lens wear.

Microbiology Studies

A series of studies based on the FDA's May 1, 1997 Guidance for Industry; Premarket Notification 510(k) Guidance Document for Contact Lens Care Products, EN ISO 14729:2001 Ophthalmic optics – Contact lens care products – Microbiological requirements and test methods for products and regimens for hygienic management of contact lenses, the ANSI Contact Lens Care Products Standard, and EN ISO 14730:2000 Ophthalmic optics -Contact lens care products - Antimicrobial preservative efficacy testing and guidance on determining discard date were completed to demonstrate the microbiological efficacy of ALCON® Multi-Purpose Disinfecting Solution.

The product meets the Stand Alone Antimicrobial Activity of the above standards both in the presence and absence of organic soil. The product passes the Regimen Criteria in the presence of soil when tested according to the directions for use. In addition, results showed that the combination of ALCON® Multi-Purpose Disinfecting Solution with OPTI-FREE® SUPRACLENS® Daily Protein Remover meets the primary criteria of the Stand Alone test.

A series of clinical studies was conducted using ALCON® Multi-Purpose Disinfecting Solution. A three-month clinical study with asymptomatic soft (hydrophilic) lens wearers, a one-month study with silicone hydrogel lens wearers and a one-month study with symptomatic soft (hydrophilic) lens wearers were conducted to demonstrate the safety and efficacy of the ALCON® Multi-Purpose Disinfecting Solution regimen with silicone hydrogel and soft (hydrophilic) contact lenses. The control products were the Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution regimen and the Advanced Medical Optics Complete MoisturePLUS Multi-Purpose Solution regimen used according to the current approved label. The safety and efficacy of the ALCON® Multi-Purpose Disinfecting Solution regimen were clinically acceptable and similar to the marketed comparator regimens when used according to the approved label. Lenses cared for with the ALCON® Multi-Purpose Disinfecting Solution regimen had statistically lower levels of lens deposits than the control regimens. In at least one of the three studies, subjects assigned to the ALCON® Multi-Purpose Disinfecting Solution regimen had statistically lower corneal staining and significantly improved comfort (on some measures of comfort) compared to one of the predicate product regimens. An additional clinical study was conducted to evaluate the effect of the ALCON® Multi-Purpose Disinfecting Solution regimen on the wetting characteristics of soft (hydrophilic) contact lenses. (This study is also cited above in the Wettability Studies section.) The control product was Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution regimen used according to the current approved label. Lenses were rinsed and disinfected overnight in the assigned multi-purpose solution. The differences in lens wettability after wear between ALCON® Multi-Purpose Disinfecting Solution and Bausch & Lomb ReNu Multi-Purpose Solution were statistically significant (p ≤ 0.0001) in favor of ALCON® Multi-Purpose Disinfecting Solution.
