Abstract:
An ophthalmoscopic surgical contact lens for placement on an eye of a patient is disclosed. The surgical contact lens includes an optic surrounded by a rim and at least one flange. The optic includes an aspheric anterior surface and a posterior surface having a shape substantially corresponding to the shape of a human cornea. The rim, comprising an edge surrounding the optic, provides the user with a gripping surface conducive to manual positioning and repositioning of the lens against a human eye. The flange may include a plurality of tabs extending from a periphery of the flange, wherein each tab is shaped and configured to conform to the curvature of a human sclera. Various embodiments of the contact lenses disclosed herein facilitate the visualization of structures within the interior of an eye, such as may be necessary during vitreoretinal surgical procedures.
