IntelliWave3, Silicone Hydrogel Daily Wear Soft Contact Lens (efrofilcon A)
The IntelliWave3 sphere (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic persons with non-diseased eyes. The lens may be worn by persons who exhibit refractive astigmatism of .75 diopters or less where the astigmatism does not interfere with visual acuity.
The IntelliWave3 toric (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding 12 diopters.
The IntelliWave3 multifocal (efrofilcone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding .75 diopters and are presbyopic requiring add power of up to +4.00 diopters.
The IntelliWave3 multifocal-toric (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding 4 diopters and are presbyopic requiring add power of up to +4.00 diopters.
The IntelliWave3 irregular cornea (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons and may be prescribed in otherwise non-diseased eves that require a Soft Contact Lens for the management of irregular corneal conditions such as keratoconus and post graft fitting.
Eyecare practitioners may prescribe the lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be cleaned and disinfected using a chemical (not heat) lens care system or hydrogen peroxide disinfection systems.
The IntelliWave3 Silicone Hydrogel Daily Wear Soft Contact Lenses are fabricated from efrofilcon A, which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to became soft and pliable when immersed in an aqueous solution.
The non-ionic lens material, (efrofilcon A) is a group 2, daily wear silicone hydrogel contact lens that is not surface treated and characterized by a high water content. The lens material is composed of silicone monomers cross linked with other monomers. The lenses are made by lathe-cut for custom RX. It consists of 26% efrofilcon A and 74% water by weight when immersed in a buffered saline solution. The (efrofilcon A) name has been adopted by the United States Adopted Names Council (USAN).
In the hydrated state, the lens conforms to the curvature of the eye covering the cornea and extending slightly beyond the limbus forming a colorless, transparent optical surface. The (efrofilcon A) soft hydrophilic contact lens has a spherical back surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye. If the lens dries out, it will become hard and appear somewhat warped however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
This document describes a 510(k) premarket notification for the IntelliWave3 Silicone Hydrogel Daily Wear Soft Contact Lens. It does not present acceptance criteria or a study proving that the device meets them in the traditional sense of a performance study with defined metrics and a test set.
Instead, the submission aims to demonstrate substantial equivalence to a previously cleared predicate device (also named IntelliWave3, K100221) by showing that it has:
- Similar technological characteristics.
- Similar indications for use.
- No new questions of safety or effectiveness.
Therefore, many of the requested items in your prompt are not applicable to this type of submission. Below is a breakdown based on the provided text, indicating where information is present or absent:
Acceptance Criteria and Device Performance
The concept of "acceptance criteria" in this document is primarily focused on demonstrating substantial equivalence to a predicate device, rather than meeting specific performance metrics against a predefined threshold. The "reported device performance" refers to its measured physical properties and the results of non-clinical bench testing and biocompatibility studies, which are compared against those of the predicate device.

Detailed breakdown of your requested information:
-
A table of acceptance criteria and the reported device performance:
- See table above. The "acceptance criteria" are implied by demonstrating substantial equivalence, meaning the new device performs similarly to or better than the predicate, and meets relevant safety standards. For internal manufacturing parameters, specific tolerances are listed.
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- This submission does not involve a clinical test set or patient data in the way a diagnostic AI device might. The "testing" refers primarily to non-clinical bench testing of the physical contact lenses and material properties. The sample sizes for these tests (e.g., number of lenses tested for Dk, water content, tensile strength, or in toxicology studies) are not specified in this summary.
- The provenance (country of origin, retrospective/prospective) is not applicable as there are no clinical studies on human subjects described in this 510(k) summary.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
- Not applicable. This submission is for a medical device (contact lens), not an AI/ML diagnostic or image analysis device that would require expert-established ground truth on a test set. The ground truth for performance is established through standardized physical, chemical, and biological testing methods.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. There is no clinical test set requiring adjudication in this submission.
-
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 and does not involve AI assistance or human readers.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This device is a physical contact lens; there is no algorithm involved.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the physical and chemical properties, the "ground truth" is based on measurements obtained using standardized laboratory methods (e.g., ISO standards for Dk, preservative uptake/release).
- For biocompatibility, the "ground truth" is established by results from validated biological tests (e.g., ISO 10993 series for cytotoxicity, systemic toxicity, irritation, sensitization).
- There is no "expert consensus" or "pathology" in the context of clinical disease for this submission, as clinical studies were deemed unnecessary.
-
The sample size for the training set:
- Not applicable. This submission does not involve machine learning or a "training set."
-
How the ground truth for the training set was established:
- Not applicable. There is no "training set" in this submission.
