The New Vision SC Daily Wear Ortho-K (tisilfocon A) Corneo-Scleral Lens is indicated for daily wear in an orthokeratology fitting program for the temporary reduction of myopia of up to 5.00 diopters in non-diseased eyes. To maintain the orthokeratology effect of myopia reduction, lens wear must be continued on a prescribed wearing schedule.
Eyes suffering from certain ocular surface disorders may benefit from the physical protection, aqueous hydrated environment and the saline bath provided by scleral lens designs. The New Vision SC (tisilfocon A) Scleral Lens is indicated for therapeutic use for the management of irregular and distorted corneal surfaces where the subject:
- cannot be adequately corrected with spectacle lenses
- requires a rigid gas permeable contact lens surface to improve vision
- is unable to wear a corneal rigid gas permeable lens due to corneal distortion or surface irregularities
Common causes of corneal distortion include but are not limited to corneal infections, tractions as a result of scar formation secondary to refractive surgery (e.g. LASIK or radial keratotomy) or corneal transplantation. Causes may also include corneal degeneration (e.g. keratoconus, keratoglobus, pellucid marginal degeneration, Salzmam's nodular degeneration) and corneal dystrophy (e.g., lattice dystrophy, granular corneal dystrophy, Reis-Bucklers dystrophy, Cogan's dystrophy).
The New Vision SC (tisilfocon A) Scleral Lens is indicated for therapeutic use in eyes with ocular surface disease (e.g. ocular Graft-versus-Host disease, Sjögren's syndrome and Filamentary Keratitis), limbal stem cell deficiency (e.g. Stevens-Johnson syndrome, chemical radiation and thermal burns), disorders of the skin (e.g. atopy. ectodermal dysplasia), neurotrophic keratiis (e.g. Herpes simplex, Herpes zoster, Familial Dysautonomia), and corneal exposure (e.g. anatomic, paralytic) that might benefit from the presence of an expanded tear reservoir and protection against an adverse environment. When prescribed for therapeutic use for a distorted cornea or ocular surface disease, the New Vision SC (tisilfocon A) Scleral Lens may concurrently provide correction of up refractive error.
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.
The NewVision SC (tisilfocon A) Scleral Lens is a large diameter rigid gas permeable lens designed to vault over the cornea and rest on the conjunctiva overlying the sclera. The New Vision SC Daily Wear Ortho-K (tisilfocon A) Corneo-Scleral Lens partly rests on the cornea, centrally or peripherally, and partly on the limbus or conjunctiva over the sclera. The NewVision SC and New Vision SC Daily Wear Ortho-K (tisilfocon A) Lenses are lathe cut from tisilfocon A, which is an FDA Group #3 fluoro-silicone acrylate material.
The provided document is a 510(k) premarket notification for a medical device (contact lenses) and does not contain information about an AI/ML-based device or a study involving AI/ML performance. Therefore, I cannot extract the required details such as acceptance criteria, performance metrics, sample sizes for test and training sets, expert qualifications, ground truth establishment, or MRMC studies, as these concepts are not applicable to the content of this document.
The document discusses the substantial equivalence of the NewVision SC and NewVision SC Daily Wear Ortho-K (tisilfocon A) Lenses to a legally marketed predicate device (Optimum Infinite (tisilfocon A) Daily Wear Contact Lenses). The performance data cited are "Non-Clinical Studies" (bench testing and bioburden testing) and "Clinical Studies" based on previous 510(k) clearances, rather than a new clinical study.
Therefore, I cannot provide the requested table or answer the specific questions related to an AI/ML device study.

Dear Bret Andre:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

VII. PERFORMANCE DATA
~ Non-Clinical Studies ~
Non-clinical testing to demonstrate the safety and effectiveness of contact lenses manufactured from tisilfocon A has been addressed by reference to previous 510(k) clearances.
Additionally, the following testing was performed on finished NewVision SC and NewVision SC Daily Wear Ortho-K (tisilfocon A) Lenses:
Bench Testing-manufacturing verification testing was conducted to demonstrate the ability of Acculens, Inc. to manufacture lenses, on a repeatable basis, from supplied lens blanks to a variety of prescribed parameters. All lenses were manufactured to established finished product specifications within the ANSI Z80.20 tolerance.
Bioburden Testing-bioburden testing conducted on rigid gas permeable lenses manufactured at Acculens, Inc. demonstrated that the colony forming units (CFU) per lens was within the established acceptance criteria of less than 100 CFU per lens.
~ Clinical Studies ~
Clinical testing to demonstrate the safety and effectiveness of contact lenses manufactured from tisilfocon A with the labeled indications for use has been addressed through previous 510(k) clearances.
- ~ Conclusions Drawn from Testing ~
Results from testing and other information presented in this premarket notification supports the substantial equivalence claim by demonstrating no relevant differences regarding the safety and effectiveness of the NewVision SC and NewVision SC Daily Wear Ortho-K (tisilfocon A) Lenses compared to the predicate devices.
VIII. CONCLUSIONS
Substantial Equivalence
Information presented in this premarket notification establishes that New Vision SC and New Vision SC Daily Wear Ortho-K (tisilfocon A) Lenses for daily wear are as safe and effective as the predicate device when used in accordance with the labeled directions for use and for the proposed indications.
Risks and Benefits
The risks of the subject device are the same as those normally attributed to the wearing of rigid gas permeable (RGP) daily wear contact lenses. The benefits to the patient are the same as those for other RGP contact lenses.
§ 886.5916 Rigid gas permeable contact lens.
(a)
Identification. A rigid gas permeable contact lens is a device intended to be worn directly against the cornea of the eye to correct vision conditions. The device is made of various materials, such as cellulose acetate butyrate, polyacrylate-silicone, or silicone elastomers, whose main polymer molecules generally do not absorb or attract water.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
