The Acuity 100 (hexafocon A), Acuity 85 (oprifocon A), Acuity 58 (enflufocon B) and Acuity 18 (enflufocon A) Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, hyperopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D to +20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lens may be disinfected using a chemical disinfection system only. The lenses may be stored in a multipurpose solution (BOSTON SIMPLUS or Menicon Unique pH) solution up to 30 days.

The Acuity Polymers Rigid Gas Permeable Contact Lenses are daily wear rigid gas permeable contact lenses comprised of fluoro-silicon acrylate copolymers wet shipped in Boston SIMPLUS Multi-Action Solution or Menicon Unique pH Multi-purpose solution.

The provided text describes the regulatory clearance of "The Acuity 100 (hexafocon A), Acuity 85 (oprifocon A), Acuity 58 (enflufocon B) and Acuity 18 (enflufocon A) Rigid Gas Permeable Contact Lenses." However, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with specific acceptance criteria and results.

Therefore, the requested information regarding acceptance criteria, reported device performance, sample sizes, ground truth establishment, expert qualifications, adjudication methods, multi-reader multi-case studies, or standalone performance studies is not found in the provided document.

The document explicitly states: "Clinical data is not necessary as the products, both RGP lenses and multi-purpose disinfection solutions are cleared for use as indicated."

Instead, the submission relies on:

• Substantial Equivalence: The primary method for demonstrating safety and effectiveness is by showing that the new device is substantially equivalent to a legally marketed predicate device (BOSTON RGP Lenses Wet Shipped in Boston SIMPLUS Multi-Action Solution, K073184).
• Prior Clearances for Materials and Solutions: The gas permeable lens materials themselves (Acuity 100, Acuity 18, Acuity 85, Acuity 58) were previously cleared under separate 510(k)s. The multi-action solutions (BOSTON SIMPLUS and Menicon Unique pH) were also previously cleared. The current submission bundles these cleared components.
• Biocompatibility Testing: The materials have been tested and found to meet biocompatibility requirements listed in the FDA Daily Wear Contact Lens Guidance Document, May 1994, and ISO 10993-1 (2009).
• Solution Compatibility Studies: Previous 510(k)s for the individual RGP lens materials included solution compatibility studies demonstrating stable lens parameters when using the specified solutions.
• Microbiological Methods (Bioburden Studies): Bioburden studies (in accordance with ISO 11737-1) were conducted to monitor lens manufacturing. These were extended to evaluate wet storage and shipping for up to 30 days, finding "no CFUs were found at any test point during the 30-day period." This represents a specific "performance" aspect, but not in the context of clinical efficacy.
• Conformance to Standards: The quality system conforms to ISO Standard 13485 (2003).

In summary, the document argues that the device meets regulatory requirements by demonstrating substantial equivalence to a predicate device and by referencing prior clearances and standard-based testing for its constituent materials and solutions, rather than presenting a new, dedicated study with specific performance acceptance criteria.

The Ampleye Scleral RGP Lens (roflufocon D, roflufocon E, hexafocon A, paflufocon D) for daily wear is indicated for use for the management of irregular astigmatism, corneal degeneration or dystrophy caused by keratoconus, keratoglobus, pellucid marginal degeneration (PMD), post corneal trauma/scaring, post keratoplasty, post K-Pro, post RK, post LASIK, Salzmann's nodular degeneration. Cogan's dystrophy, granular corneal dystrophy, lattice corneal dystrophy or Reis-Bucklers dystrophy.

The Ampleye Scleral RGP Lens (roflufocon D, roflufocon E, hexafocon A, paflufocon D) is also indicated for therapeutic management of ocular surface disease from dry eye including ocular pemphigoid, Stevens-Johnson syndrome, symblepharon formation, graft vs host disease, persistent epithelial defect, exposure keratitis, neurotrophic keratopathy( herpes zoster, familial dysautonomia), Sjogern's syndrome, filamentary keratitis, limbal stem cell deficiency, atopy, ectodermal dysplasia. When prescribed for therapeutic use for irregular astigmatism or ocular surface diseases, the Ampleye Scleral RGP Lens may also provide correction of refractive error including myopia, presbyopia and regular astigmatism.

Eye care 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 Ampleye Scleral RGP Lens (roflufocon D, roflufocon E, hexafocon A, paflufocon D) for daily wear is a large diameter rigid gas permeable contact lens design that vaults over the cornea and rests on the conjunctiva overlying the sclera. The Ampleye Scleral RGP Lens is lathe cut from one of the following hydrophobic, FDA Group #3 fluoro-silicone acrylate materials: roflufocon D, roflufocon E, hexafocon A, or paflufocon D.

The provided document is a 510(k) summary for a contact lens device, the Ampleye Scleral RGP Lens. This type of submission focuses on demonstrating substantial equivalence to a predicate device rather than undergoing a full clinical study with acceptance criteria in the way a novel therapeutic or diagnostic device would.

Therefore, the information typically requested in your prompt regarding acceptance criteria and detailed study results for device performance (e.g., accuracy, sensitivity, specificity, statistical significance with effect size) is not present for this contact lens device in this particular document.

Here's how to interpret the document in the context of your request:

1. Table of Acceptance Criteria and Reported Device Performance:

• No specific acceptance criteria for a "device performance" study (e.g., accuracy metrics) are provided.
• Instead, the "performance" demonstrated is the ability to manufacture lenses to established finished product specifications within ANSI Z80.20-2016 tolerance and bioburden levels within acceptance criteria. These are manufacturing and safety standards, not clinical performance metrics in the sense of predictive or diagnostic accuracy.
