ABSTRACT:
The invention provides a sapphire surgical contact lens to view interior structures and regions of an eye as well as methods for making and using such a surgical contact lens. The surgical contact lens includes a transparent member comprising sapphire and having a first and a second surface. The first surface may be configured in a variety of ways, e.g. with a geometry that complements the curvature of a cornea, in particular the cornea's radius of curvature. More particularly the first surface is suitably configured so as to be generally concave so as to form a portion of a spherical surface. The second surface is configured with a geometry that, in cooperation with the first surface geometry, yields a given optical configuration for viewing the interior of the eye. In a preferred aspect, the transparent member is made from a single crystal of sapphire.
