The MIERU (etafilcon A) Multifocal Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and are presbyopic. The lens may be worn by persons who exhibit no more than 2.00 D of astigmatism and can obtain satisfactory visual acuity in a power range of +4.00D to =5.00D and have near add requirements up to 3.00D. 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.

Device Story

Hydrophilic soft contact lens; etafilcon A copolymer (42% polymer, 58% water). Available as spherical, aspherical multifocal, or back surface toric designs.

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.

## Device Classification: Class II Classification Number: LPL Classification Name: Lenses, Soft Contact, Daily Wear MIERU (etafilcon A) Daily Wear Contact Lens clear and Trade Name: visibility tint, with UV blocker.

{1}------------------------------------------------

#### Equivalent Predicate Devices:

The MIERU (etafilcon A) Soft Contact Lenses are substantially equivalent to the following predicate devices:

- 1. IGEL 55UV (methafilcon A), K020855, Manufactured by IGEL Visioncare Pte. Ltd.
- 2. Frequency 58 (etafilcon A), K980634, manufactured by Aspect Vision Care.
- 3. AcuVue 2 (etafilcon A), K962804, manufactured by Vistakon.

#### Device Description:

The MIERU (etafilcon A) Soft (hydrophilic) Contact Lens is available as a single vision spherical lens, aspherical multifocal lens and as a back surface astigmatic (toric) lens. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution.

The ionic lens material, (etafilcon A) is a co-polymer of 2- hydroxyethyl methacrylate and methacrylic acid cross-linked with 1,1,1 - trimethylol propane trimethacrylate glycol demethacrylate. It consists of 42% etafilcon A and 58% water by weight when immersed in buffered saline solution. The lens polymer contains a UV absorbing compound and is available clear or with a blue visibility-handling tint, color additive 'Reactive Blue 19', 21 CFR part 73.3121. The (etafilcon A) name has been adopted by the United States Adopted Names Council (USAN).

In the MIERU Contact Lens with UV Blocker, a Benzophenone UV absorbing monomer is used to block UV radiation. The UV blocking for MIERU averages > 99% in the UVB range of 280nm - 315nm and 83% in the UVA range of 316 - 380nm.

In the hydrated state, the lens conforms to the curvature of the eye covering the cornea and extending slightly bevond the limbus forming a colorless, transparent 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. 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.

The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 58% water by weight. The physical properties of the lens are:

| Refractive Index | 1.4050 (wet) |
|-----------------------------|-------------------------------------------------------------------------|
| Light Transmission (clear) | greater than 95% |
| Light Transmission (tinted) | greater than 91% |
| Water Content | 58 % |
| Specific Gravity | 1.017 (hydrated) |
| Oxygen Permeability | 19.9 X 10-11 (cm2/sec) (ml O2/ml x mm Hg @ 35°C), (revised Fatt method) |
