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

The document does not explicitly state numerical sample sizes for most non-clinical tests.

Solution Compatibility: Tested with "conventional Group 1 and Group 4 soft (hydrophilic) contact lenses" and "four (4) representative marketed silicone hydrogel lenses."
Protein Removal: Tested using AMO Brand MPDS and the predicate device.
Wettability: Tested using "four (4) representative silicone hydrogel contact lenses and FDA Group IV contact lenses."
Microbiological Studies:
- Disinfection: Evaluation against "bacteria, yeast, and mold." The specific number of organisms or replicates is not stated.
- Sterility: No specific sample size given for USP <71> test.
Biocompatibility:
- Cytotoxicity: Mouse fibroblasts (number not specified).
- Sensitization: Dermal reactions (number of subjects/animals not specified).
- Ocular Irritation: Rabbits (number not specified, but typically 3-6 per group for acute irritation).
- 22-day Ocular Safety: Rabbits (number not specified, but uses "control" and "test formulation" with two lens types: PureVision™ or Acuvue® 2).
- Acute Oral Toxicity: Rats (number not specified).
- Cytotoxicity with pre-soaked contact lenses: Mouse fibroblasts (number not specified).
Clinical Trials:
- Multi-center clinical trial: "Soft contact lenses, including silicone hydrogel lens wearers." No specific number of participants.
- Single-center clinical trial: Used "PureVision™ lenses at specified time points over a period of four days." No specific number of participants.

Data Provenance: The studies appear to be prospective as they were conducted to test the specific device for regulatory submission. The country of origin is not explicitly stated for the test data, but the submitter (Abbott Medical Optics) is based in Santa Ana, CA, USA, and the submission is to the US FDA, implying the studies were conducted to US regulatory standards, likely within the US or by internationally recognized laboratories.

3. Number of Experts and Qualifications for Ground Truth

This information is not provided in the document. For laboratory-based non-clinical studies, "ground truth" is typically established by laboratory standards and protocols, not expert consensus in the same way it would be for clinical image interpretation. Clinical trials would involve ophthalmologists or optometrists for evaluations (e.g., corneal staining, adverse events), but their specific qualifications and number are not detailed.

4. Adjudication Method

This information is not applicable to most of the non-clinical tests described (e.g., microbiological, chemical analysis, animal studies) where results are quantitative or based on defined criteria. For the clinical trials, the document does not specify any adjudication method (e.g., 2+1, 3+1) for participant observations or outcomes.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, a MRMC comparative effectiveness study was not done. This type of study (comparing human readers with and without AI assistance) is relevant for diagnostic imaging devices. The AMO Brand Multi-Purpose Disinfecting Solution is a contact lens care product, not a diagnostic imaging device.

6. Standalone (Algorithm Only) Performance Study

No, a standalone (algorithm only) performance study was not done. This concept is also primarily relevant for AI/ML-based diagnostic devices. The device described is a chemical solution; its "performance" is assessed through its physical, chemical, and biological interactions, not by an algorithm's output.

7. Type of Ground Truth Used

The "ground truth" for the various tests was established through:

Laboratory Standards and Protocols:
- Microbiological: Quantitative measurements of microbial kill (against specific bacteria, yeast, mold) as per FDA guidelines and USP <71> for sterility.
- Chemical/Physical: Measurement of protein removal, contact angles for wettability, stability metrics.
- Biocompatibility: Observation of cytotoxicity, dermal reactions, ocular irritation, oral toxicity in animal models against defined endpoints (e.g., cell viability, irritation scale).
Clinical Observations: For the clinical trials, the "ground truth" for safety and performance (e.g., patient acceptability, comfort, corneal staining, adverse events) would be based on direct patient feedback and objective examinations by trained healthcare professionals (e.g., ophthalmologists, optometrists).

8. Sample Size for the Training Set

Not applicable. The device is a chemical solution, not an AI/ML algorithm that requires a training set.

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

Not applicable. There is no training set for this type of device.

Solution Compatibility: AMO Brand Multi-Purpose Disinfecting Solution was tested for compatibility with conventional Group 1 and Group 4 soft (hydrophilic) contact lenses, and with four (4) representative marketed silicone hydrogel lenses. The results demonstrate the product is compatible with soft contact lenses, including silicone hydrogel lenses. The tests were primarily carried out in accordance with the FDA Guidelines, Premarket Notification (510(k)) Guidance Documents for Contact Lens Care Products, May 1, 1997.

Protein Removal: AMO Brand Multi-Purpose Disinfecting Solution and the predicate device were tested for their abilities to remove lysozvme protein on contact lens surfaces. AMO® Brand Multi-Purpose Disinfecting Solution demonstrated its ability to passively and effectively remove protein from soft (hydrophilic) contact lenses, including silicone hydrogels, which is comparable to the predicate device.

Wettability of Contact Lenses: The contact angles of water drops on contact lenses were measured using the sessile drop method. Contact lenses, including four (4) representative silicone hydrogel contact lenses and FDA Group IV contact lenses, were presoaked in MPDS 9608X, or the predicate device, Opti-Free® RepleniSH®. The results demonstrate AMO® Brand Multi-Purpose Disinfecting Solution and Opti-Free® RepleniSH® are equivalent in soft (hydrophilic) contact lens, including silicone hydrogels, wettability, conditioning, and moisturizing.

Microbiological Studies: The product was evaluated for microbiological efficacy using studies outlined in FDA's Premarket Notification (510(k)) Guidance Documents for Contact Lens Care Products, May 1, 1997, modified to include organic soil in the stand alone test and test solution formulated to the low specification of the disinfectants / preservatives.

The product meets current FDA requirements for disinfection of contact ● lenses against bacteria, yeast, and mold at low shelf specifications for the disinfectant / preservative system.
AMO brand Multi-Purpose Disinfecting Solution is formulated with dualdisinfection technology designed specifically for soft contact lenses, including silicone hydrogel lenses. Dual disinfectants work to destroy microbes on the surface of the lens and provide safe contact lens storage up to 30-days. All
