• Attributes: Therapeutic

Intended Use

The OPTIMUM GP OK contact lenses are 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. Eyecare practitioners may prescribe the lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent wear, the lens may be cleaned and disinfected using a chemical (not heat) lens care system.

Device Story

Rigid gas permeable contact lens; material: roflufocon D & E (fluoro silicone acrylate copolymer); lathe-cut manufacturing. Used in orthokeratology fitting programs for temporary myopia reduction. Prescribed by eyecare practitioners for daily wear; frequent/planned replacement. Patient wears lens to reshape cornea; effect maintained through consistent wear schedule. Shipped wet or dry in polypropylene cases; wet shipping uses Optimum CDS solution. Includes visibility tint and optional UV-blocking monomer (benzophenone). Benefits patient by providing temporary vision correction without surgery.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on the established safety profile of the roflufocon D & E material (previously cleared under K033594) and comparison of physical/mechanical properties to predicate orthokeratology lenses.

Technological Characteristics

Rigid gas permeable contact lens; material: fluoro silicone acrylate (roflufocon D & E); water content <1%; Dk 100-125 x 10^-11 (ISO/FATT); refractive index 1.433; UV blocker (2,2-Dihydroxy-4,4'dimethoxybenzophenone) available; lathe-cut production; visibility tint (D&C Green No. 6, FD&C Red No. 17, CI Solvent Yellow 18).

Indications for Use

Indicated for daily wear in an orthokeratology fitting program for temporary reduction of myopia up to 5.00 diopters in non-diseased eyes. Requires continued wear on a prescribed schedule to maintain effect.

Regulatory Classification

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.

The OPTIMUM GP OK Daily Wear Contact Lens (roflufocon D & E) is a rigid gas permeable methacrylate copolymer of Methyl methacrylate, 1,1,1,3,3 - Hexafluoroisopropy] Methacrylate, Methacryloxypropyl Tris(trimethylsiloxy) silane, 1,3-bis(methacryloxypropyl)-1,1,3,3-tetrakis(trimethyl siloxy)disiloxane, 2-Hydroxyethyl Methacrylate, and Methacrylic acid cross-linked with Ethylene Glycol Dimethacrylate.

The OPTIMUM GP OK Daily Wear Contact Lens (roflufocon D & E) may be packaged and shipped "dry" or "wet" in a polypropylene contact lens case. The primary container for shipping the OPTIMUM GP OK lenses is the PolyVial /PolyPack Contact Lens Case. When shipped "wet", the OPTIMUM GP OK lenses may be packaged and shipped in the Optimum Cleaning, Disinfecting and Storage (CDS) GP solution. The active ingredients in Optimum GP Cleaning Disinfecting and Storage solution are Lauryl salt of imidazoline, octylphenoxypolyethoxyethanol, and preserved with benzyl alcohol 0.3% and disodium edetate 0.5%.

The OPTIMUM GP OK Daily Wear Contact Lens (roflufocon D & E) is substantially equivalent to the OPTIMUM GP (Oxygen Permeable) Daily Wear Contact Lenses (roflufocon A, B, C, D, & E)cleared under K033594-in terms of the following:

- · contact lens material (roflufocon D. & E)—including physicochemical and mechanical properties of finished lenses
- · lathe cut manufacturing process
- manufacturing facility
- · final packaging and wet shipping procedures

The OPTIMUM GP OK Daily Wear Contact Lens (roflufocon D & E) is substantially equivalent to the Boston X02 (hexafocon B) Daily Wear Contact Lens and CONTEX OK-cleared under K071266 and K973697, respectively-in terms of the following:

- · indications for use (daily wear orthokeratology)
- orthokeratology lens design

The OPTIMUM GP OK Daily Wear Contact Lens (roflufocon D & E) are substantially equivalent to the predicate device as depicted in the following table, and do not raise different questions of safety and effectiveness than the predicate device identified previously.
