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)
The physical/optical properties of the lenses are:
• Refractive Index: 1.4003
• %Transmittance @ 590nm: 98.13
• %Transmittance @ 280-315nm: 0.71
• %Transmittance @ 316-380nm: 20.62
• Surface Character: Hydrophilic
• Water Content: 56%
• Oxygen Permeability (DK): 60 x 10-11 (cm²/sec)(ml O2/ml x mmHg) at 35°C (Fatt Method for determination of oxygen permeability)
• Specific Gravity: 1.17
The provided document describes a 510(k) premarket notification for a contact lens, Clariti 1 day (somofilcon A) Soft (Hydrophilic) Daily Disposable Contact Lens with UV Blocker. The submission asserts substantial equivalence to a predicate device and does not involve performance testing to support this claim, but rather a change from biological release to parametric release of the finished product. Therefore, the document does not describe a study testing the acceptance criteria of the device.
However, it does list several performance specifications/parameters for the device, which can be interpreted as acceptance criteria based on its equivalence to the predicate device.
Here's the information derived from the document, with explanations for aspects not explicitly stated:
1. A table of acceptance criteria and the reported device performance (based on the predicate device's performance properties):
| Acceptance Criteria (Performance Specifications/Parameters) | Reported Device Performance (Subject Device) | Comments |
|---|---|---|
| Water Content (%) | 56 | Same as predicate |
| Refractive Index | 1.401 | Same as predicate |
| Oxygen Permeability (Dk @ 35°C) | $60 x 10^{-11} [(cm^2/sec) x (ml O_2)/(ml x mm Hg)]$ | Same as predicate |
| Base Curve (mm) | 8.6 | Same as predicate |
| Diameter (mm) | 14.0 | Same as predicate |
| Light Transmittance (%) | >95 | Same as predicate |
| Modulus (MPa) | ≥0.3 | Same as predicate |
| Tensile Strength (MPa) | ≥0.4 | Same as predicate |
| Elongation to Break (%) | ≥100 | Same as predicate |
| Surface Treatment | No | Same as predicate |
| Center Thickness (mm) | Varies with power | Same as predicate |
| Power Range (D) | -20.00 to + 20.00 | Same as predicate |
| UV Blocker Transmittance (UVB range of 280 to 315nm) | < 5% | Based on description of UV absorbing monomer |
| UV Blocker Transmittance (UVA range of 316-380nm) | < 50% | Based on description of UV absorbing monomer |
2. Sample size used for the test set and the data provenance:
- Not applicable. The document explicitly states: "The modification does not warrant performance testing to support substantial equivalence." This means a new performance study to test acceptance criteria was not conducted for this submission. The equivalence is based on a change in manufacturing release method (from biological to parametric).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. No new performance study was conducted.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. No new performance study was conducted.
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:
- Not applicable. This device is a contact lens, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This device is a contact lens, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable. No new performance study was conducted. The "ground truth" for the device's properties is established through the physical/optical properties of the lens material and design, which are stated to be identical to the predicate device.
8. The sample size for the training set:
- Not applicable. No new performance study was conducted.
9. How the ground truth for the training set was established:
- Not applicable. No new performance study was conducted.
