Abstract: A contact lens having a rotational stabilization mechanism thereon, such as prism ballast, and a thickness profile that reduces the torque imparted on the lens by the action of the eyelids, especially for stabilizing toric lenses. The prism ballast is provided on one or more portions of the anterior face of the lens such that the lens body has a uniform thickness of within 10% along horizontal cross-sections. The anterior face of the lens may be segregated into a peripheral zone, an inner zone circumscribed by the peripheral zone, and a central optic zone. The prism ballast portion is provided within the inner zone, which may be further subdivided into a superior portion, an intermediate portion proximate the optic zone, and an inferior portion. The ballast portion increases in thickness along a superior-inferior line parallel to a vertical meridian, and has a substantially uniform thickness perpendicular thereto. The peripheral zone may be tapered, and have a rounded edge. The rate of thickness change across any portion of the peripheral zone is less than about 250 μm/mm.

Abstract: Corneal onlays and corneal onlay production methods are described. The present corneal onlays include a lens body. An example of a corneal onlay includes a lens body that includes a corneal epithelium-contactable anterior surface and a Bowman's membrane-contactable posterior surface. The lens body has an optical power from about −10 diopters to about +10 diopters, an optic zone diameter from about 5 mm to about 11 mm, a base curve from about 5 mm to about 12 mm, a center thickness from about 10 micrometers to about 300 micrometers, and an edge thickness from about 0 micrometers to about 120 micrometers. Methods include forming the present corneal onlays from polymeric materials.

Abstract: Ophthalmically compatible contact lenses include lens bodies configured for placement on a cornea of an animal or human eye. The lens bodies are made of a hydrophilic silicon-containing polymeric material. The lens bodies have oxygen permeabilities, water content, surface wettabilities, flexibilities, and/or designs to be worn by a lens wearer even during sleep. The present lenses can be worn on a daily basis, including overnight, or can be worn for several days, such as about thirty days, without requiring removal or cleaning.
