Device Description

The Clariti 1 day (somofilcon A) Soft (Hydrophilic) Daily Disposable Contact Lens with UV Blocker is available as sphere lens, toric lens, multifocal lens, and multifocal toric lens.

In its hydrated state, Clariti 1 day (somofilcon A) Soft (hydrophilic) Daily Disposable Contact Lens with UV Blocker when placed on the cornea acts as a refracting media to focus light rays on the retina.

Clariti 1 day (somofilcon A) Soft (hydrophilic) Contact Lenses for Daily Wear Single Use are a hydrophilic co-polymer of silicone containing monomers and hydrophilic monomers which is cross-linked with tetraethyleneglycol dimethacrylate and di-functional methacryloxypropyl-terminated poly(dimethylsiloxane).

When hydrated the lens consists of 44.0% somofilcon A and 56.0% water by weight of saline immersed in normal saline. A benzophenone UV absorbing monomer is used in the contact lens to help protect against transmission of harmful UV radiation and Clariti 1 day (somofilcon A) Soft contact lenses help protect against transmission of harmful UV radiation to the cornea and into the eye.

The average transmittance characteristics are less than 5% in the UVB range of 280 to 315nm and less than 50% in the UVA range of 316-380nm.

The lens has a hemispherical flexible shell, which covers the cornea and a portion of the adjacent sclera, with the following dimensions:

Chord Diameter: 13.0mm to 15.5mm
Centre Thickness: 0.03mm to 0.50mm
Base Curve: 7.5mm to 9.30mm
Powers: -20.00 DS to +20.00 DS
Toric Cylinder options: -0.75, -1.25, -1.75 and -2.25
Toric Axis options: 10° to 180° (10° steps)
Multifocal Add: Lens "LOW" = "low" for spectacle near ADD lens (Max +2.25 ADD) Lens "HIGH" = "high" for spectacle near ADD lens (+2.50 ADD or greater)

Key Differences Between Subject and Predicate Device:
There were two technological differences between the subject device (K181920) and the predicate device (K130331) that required performance data:

Addition of 4,4'-Diallyoxyl benzophenone (DAB): The subject device includes both UV416 and DAB as UV blockers, whereas the predicate only had UV416.
Change from borate to phosphate buffered packaging solution: The subject device uses Phosphate Buffered Saline Solution containing 0.020% w/v Poloxamer 407, while the predicate used Borate Buffered Saline Solution containing 0.005% w/v Poloxamer 407.

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

The document states that "Conclusive evidence was provided to demonstrate that the subject device lens material is equivalent to the currently marketed predicate device lens material through the statistical analysis of the physiochemical properties, especially water content, oxygen permeability, modulus, and toughness of the lens."

For the performance testing (bench testing), the document mentions that "Each test was conducted according to the ANSI, ISO, and/or ASTM standard indicated." However, specific sample sizes for the test set are not provided in the given text.

The data provenance is not explicitly stated as country of origin, but the testing was conducted in accordance with international standards (ISO, ANSI, ASTM) and FDA guidance documents (e.g., Use of International Standard ISO 10993-1, Premarket Notification [510(k)] Guidance Document for Daily Wear Contact Lenses). This implies that standard laboratory testing was performed, likely at the manufacturer's or a contract research organization's facilities. The studies appear to be prospective in nature, as they were conducted to support the substantial equivalence claim for the subject device.

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

This information is not applicable to this submission. The "ground truth" in this context refers to the defined physical, chemical, and optical properties of the contact lenses, as measured by standardized bench tests, and biocompatibility evaluations. These measurements do not rely on expert interpretation in the way that image-based diagnostic devices might.

4. Adjudication Method for the Test Set

This is not applicable. The performance testing involves direct physical, chemical, and optical measurements against established standards, not subjective assessments requiring adjudication.

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

An MRMC comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic devices where human readers interpret medical images. This submission is for a medical device (contact lens) where performance is assessed through bench and biocompatibility testing, not human interpretation of data. The document explicitly states: "clinical performance data was not required to be submitted in this 510(k)."

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

This is not applicable. This is not an algorithm or AI-powered device. The device's performance is assessed through its physical characteristics and biological safety.

7. The Type of Ground Truth Used

The "ground truth" for the performance criteria was established through:

Bench Testing: Measurements of physical, chemical, and optical properties (e.g., water content, oxygen permeability, refractive index, mechanical properties, light transmittance, specific gravity, contact angle, total extractables, non-polymeric residuals) using established ANSI, ISO, and ASTM standards.
Biocompatibility Testing: Evaluation according to ISO 10993 series for cytotoxicity, irritation, systemic toxicity, and sensitization.
Comparison to Predicate: The key ground truth was the established performance of the legally marketed predicate device (Clariti 1 day, K130331), demonstrating that the subject device's performance was "Same" or equivalent across all measured parameters despite minor material and packaging solution changes.

8. The Sample Size for the Training Set

This is not applicable. This submission is for a physical medical device (contact lens), not an AI algorithm. Therefore, there is no "training set" in the context of machine learning.

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

This is not applicable for the reasons stated above.

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE:

The technological principle for both the subject and predicate device somofilcon A soft (hydrophilic) contact lenses with UV blocker is identical. The subject and predicate device are based on the same technological elements. The two technological differences that exist between the subject and predicate device consist of the addition of 4,4'-Diallyoxyl benzophenone (DAB) and the change from borate to phosphate buffered packaging solution. A comparison of the technological characteristics of the subject device with the predicate device is provided in the table below.

For the technological difference of the addition of DAB, performance data was provided to demonstrate that the subject device lens material is equivalent to the currently marketed predicate device lens material. Additionally, there is no change to the USAN name of the device because additives such as UV absorbers are excluded for the purpose of nomenclature.

For the technological difference of the change from borate to phosphate buffered packaging solution, performance data was provided to ensure compatibility of the contact lens with the lens storage solution that comes into direct contact with the contact lens and to ensure that the changes in the packaging material has not compromised the sterility or stability of the contact lens for the labeled expiration date. Additionally, the requirements of the procedure for implementing changes in packaging materials, specifically the types of buffers utilized in lens packaging solutions or addition of buffers to saline solutions (e.g., borate to phosphate buffer), from the Premarket Notification [510(k)] Guidance Document for Daily Wear Contact Lenses, May 12, 1994 amended June 28, 1994 were met.

Clinical testing:

Data provided in this 510(k) is sufficient to adequately characterize the modified subject Clariti 1 day (somofilcon A) device in terms of its physical/chemical/optical, and toxicological performance characteristics when compared to the predicate. The results are equivalent determining that additional clinical performance data was not required to complete the substantial equivalent determination. Additionally, the technical characteristics and manufacturing and sterilization processes of the subject lens are equivalent to somofilcon A contact lens currently marketed by CooperVision; therefore, it was confirmed no clinical data is required.

CONCLUSIONS: VIII.

Conclusive evidence was provided to demonstrate that the subject device lens material is equivalent to the currently marketed predicate device lens material through the statistical analysis of the physiochemical properties, especially water content, oxygen permeability, modulus, and toughness of the lens. Therefore, there is no change to the USAN name of the device. Based on this performance testing and the fact that the subject device has the same manufacturing process as the marketed predicate device lens, clinical performance data was not required to be submitted in this 510(k). There were no differences in physiochemical properties, especially water content, oxygen permeability, modulus, and toughness of the lens. The performance testing demonstrates that the subject Clariti 1 day (somofilcon A) device performs comparably to the predicate Clariti 1 day (somofilcon A) device that is currently marketed for the same intended use.

{10}------------------------------------------------

The modifications made to the subject Clariti 1 day (somofilcon A) device did not have a significant impact on the performance characteristics of the 510(k) cleared predicate device. There is sufficient data provided in this 510(k) to adequately characterize the modified lens in terms of its physical/chemical/optical, and toxicological performance characteristics when compared to the previously cleared lens. Results of the pre-clinical testing (physical/chemical/optical and toxicological data) are sufficient to support the claim and clinical performance data are not needed to assess effects of the new characteristics.
