Intended Use

The Benz-G 4X 54% (Hioxifilcon D) Multifocal Lathed soft contact lens for daily wear is indicated for the correction of visual acuity in aphakic or non-aphakic persons with non-diseased eyes that are myopic, hyperopic, possess astigmatism of 10.0 diopters or less and are presbyopic. The spherical lens may be worn by persons who exhibit astigmatism of 0.75 Diopter or less that does not interfere with visual acuity. The toric lens may be worn by persons who exhibit astigmatism of up to 10 Diopters. Eye care practitioners may prescribe the lens for frequent/planned replacement wear, with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfection system.

Device Story

Benz-G 4X Multifocal Lathed soft contact lens is a hemispherical shell fabricated from Hioxifilcon D (non-ionic copolymer of 2-HEMA and GMA, cross-linked with EGDMA). Device contains 54% water by weight when hydrated. Lens features blue visibility tint (phthalocyanato (2) - (copper)). Designed for daily wear to correct visual acuity in aphakic/non-aphakic patients with myopia, hyperopia, presbyopia, and astigmatism. Prescribed by eye care practitioners for frequent/planned replacement. Lens conforms to corneal curvature, extending beyond limbus to provide transparent optical surface. Multifocal design achieved via addition of specific optical zones (OZ1: 1.8-6.2; OZ2: 6.2-1.8). Benefits include vision correction for presbyopic patients. Requires maintenance in hydrated state using compatible chemical disinfection systems.

Clinical Evidence

No clinical data. Safety and effectiveness established through bench testing and comparison of material, physical, and manufacturing characteristics to the predicate device.

Regulatory Classification

Identification

A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.

### Purpose of the 510(k) Submission:

Benz Research & Development is requesting clearance from the FDA to manufacture and market Benz-G 4X (Hioxifilcon D) Multifocal Lathed Lenses.

## Predicate Devices:

The Benz-G 4X (Hioxifilcon D) Multifocal Lathed soft contact lens is substantially equivalent to the Benz-G 4X (Hioxifilcon D) Lathed Lens already cleared under 510(k) K062854.

#### Device Description:

The Benz-G 4X (Hioxifilcon D) Multifocal Lathed soft contact lenses are hemispherical shells and are available as multifocal lens designs. The Benz-G 4X (Hioxifilcon D) Multifocal Lathed soft contact lens is fabricated from Hioxifilcon D, which is a non-ionic copolymer of 2-hydroxyethyl methacrylate (2-HEMA) and 2,3-, Dihydroxypropyl Methacrylate (Glycerol Methacrylate, GMA) and cross-linkned with ethylene glycol dimethacrylate (EGDMA). It consists of 46% Hioxifilcon Datod 54% water by weight when immersed in normal buffered saline solution buffered. The lens is available with a blue visibility handling tint, phthalocyanato (2) - (copper).

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, rransparent optical surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye.

#### Intended Use (Indications):

The Benz-G 4X 54% (Hioxifilcon D) Multifocal Lathed soft contact lens for daily wear is indicated for the correction of visual acuity in aphakic or non-aphakic persons with non-diseased eyes that are myopic, hyperopic, possess astigmatism of 10 0 diopters or less and are presbyopic. The spherical lens may be worn by persons who exhibit astigmatism of 0.75 Diopters or less that does not interfere with visual acuity. The toric lens may be worn by persons who exhibit astigmatism of up to 10.0 Diopters.

Eye care practitioners may prescribe the lens for frequent/planned replacement wear. with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfection system.

{2}------------------------------------------------

#### Comparison to Predicate Device:

Side by side comparison testing was conducted on the Benz-G 4X (Hioxifilcon D) Lathed Lens already cleared under 510(k) K062854, and Multifocal Lenses manufactured by Benz Research & Development from Hioxifilcon D material.

#### Clinical Data:

It was determined that clinical studies were not necessary to establish the safety and effectiveness of the Benz-G 4X (Hioxifilcon D) Multifocal Lathed lenses.

This Benz-G 4X (Hioxifilcon D) material is identical to the previously cleared Benz-G 4X (Hioxifilcon D) under K062854.

The Benz-G 4X (Hioxifilcon D) Multifocal Lathed lenses have the identical manufacturing process (lathe-cut versus lathed-cut) as the marketed lens Benz-G 4X (Hioxifilcon D) Lathed.

#### Conclusion:

The information provided in this premarket submission establishes that the Benz-G 4X (Hioxifilcon D) Multifocal Lathed lenses is substantially equivalent in terms of intended use, materials, toxicological and physiochemical properties to the predicate device, Benz-G 4X (Hioxifileon D) Lathed Lens. This change is to correct the visual acuity in aphakic and nonaphakic persons with non-diseased eyes that are myopic, hyperopic, possess astigmatism of 10.0 diopters or less and are presbyopic. This visual acuity correction is achieved with the addition of another optical zone.
