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 Description:

The QUASAR® - QUASAR PLUS® - QUASAR TORIC® Contact Lenses are fabricated from the hydrophobic contact lens materials (hybufocon A, paflufocon B). When placed on the human cornea, the QUASAR® - QUASAR PLUS® - QUASAR TORIC® rigid gas permeable contact lenses act as a refracting medium to focus light rays upon the retina.

The QUASAR® and QUASAR TORIC® series of contact lenses are aspheric from center to edge. The QUASAR® and QUASAR TORIC® are designed with the central area consisting of a modified conic profile, which is designed to flatten at a much slower rate than a fixed elliptical curve. (see figure below). This improves centration characteristics and eliminates any significant positive/astigmatic aberration over the central 7mm. This aspheric geometry results in slight apical clearance and close alignment over the mid-peripheral cornea. Edge clearance is achieved by the addition of a second aspheric edge band resulting in the optimal final tear lens profile as shown in the figure below. Constant apical and edge clearance are maintained independent of base curve and the total diameter of the lens.

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

Image /page/2/Figure/0 description: The image contains two figures. Figure 1 shows a graph of the Quasar curve, with the x-axis labeled as "Primary sag (u) (x coordinates) not drawn to scale" and the y-axis labeled as "Semi-diameter y (mm)". The graph shows three curves: Quasar curve, Elliptical curve, and Spherical curve, with an axial lift at approximately 5. Figure 2 shows the back surface profile of the Quasar lens, with labels indicating the edge radius, axial edge lift, peripheral aspheric "ski-bever" (0.6mm), semi-diameter 4.8mm, spherical curve, and central progressive aspheric zone (8.40mm).

The QUASAR PLUS® multifocal design cleverly utilizes the eyes' own tears to provide precise vision at distance, intermediate and near. The QUASAR PLUS® is a distance center multifocal with a graduated annulus of near vision where the progressive power is incorporated into the optics back surface of the The aspheric design of the optical zone is based upon the patient's degree of ametropia and the lens. reading addition required. By incorporating the asphericity into the back surface, the profile of the tear film will be altered resulting in a fluorescein pattern different than that of a single vision lens.

#### Substantial Equivalence:

The new device will be manufactured according to specified process controls and a Quality Management System certified to QSR guidelines. The new device will undergo manufacturing, packaging and other process procedures similar to RGP devices currently marketed and distributed by No 7 Contact Lens Laboratory Ltd. The established safety profile (pre-clinical toxicology and manufacturing/chemistry data) of the device was established in the following referenced FDA approvals:

| (hybufocon A) | 510(k), K021977 |
