Abstract
A direct view sclera contact lens suitable for use in direct selective laser trabeculoplasty (DSLT) procedures. With use of the direct view sclera contact lens, DSLT can be carried out with conventional SLT lasers that are commonly available. The direct view sclera contact lens comprises a lens body having an inferior end that defines a light exit surface. The light exit surface extends inwardly toward the optical axis and in a superior direction to form a compression annulus. The compression annulus contacts an eye of the patient during direct selective laser trabeculoplasty. The lens body includes a ring of evenly spaced alignment markers disposed in the light exit surface.
Claims9
A contact lens for use in direct selective laser trabeculoplasty, the contact lens comprising:
- a lens body having an optical axis and an inferior end that defines a light exit surface, the light exit surface extending inwardly toward the optical axis and in a superior direction to form a compression annulus, wherein the compression annulus contacts an eye of the patient during direct selective laser trabeculoplasty, and wherein the lens body includes a ring of evenly spaced alignment markers disposed in the light exit surface.
A contact lens for use in direct selective laser trabeculoplasty, the contact lens comprising:
- a lens body that includes a superior end that defines a light entry surface that is planar and is oriented orthogonally to an optical axis of the lens and an inferior end that defines a light exit surface, the light exit surface extending inwardly toward the optical axis and in a superior direction to form a compression annulus, wherein the lens body also includes a first cavity in the form of a spherical recess that extends in a superior direction from the inner rounded edge of the compression annulus, and wherein the lens body further includes a plurality of alignment markers formed into the light exit surface and are arranged in a ring-like pattern.
