A contact lens comprising one or more microchannels for transport of liquid through the lens is provided. The contact lens can be made by contacting a curable composition with a microfiber that is insoluble in the curable composition; curing the curable composition to provide a polymeric lens body with the microfiber embedded therein; and contacting the polymeric lens body with a solvent to dissolve the microfiber.

Contact lenses with microchannels

A contact lens having dimples on a posterior surface is described as well as cast molds and injection molding inserts for manufacturing the same. The contact lens includes a posterior surface having an optic zone, a peripheral zone, and a circumferential edge, where dimples are located in the peripheral zone, and can include at least 1000 dimples.

Dimpled contact lens

Contact lens curing systems and methods are described. A contact lens curing system includes an oven that has a plurality of curing zones, a mold advancement system for moving contact lens mold assemblies between the plurality of zones, and a controlled atmosphere in the curing zones that provides a substantially chemically inert environment in which contact lens precursor materials can be polymerized in contact mold assemblies located in the curing zones. Methods of producing contact lenses include curing contact lens precursor materials in contact lens mold assemblies in the lens curing system.

Thermal curing methods and systems for forming contact lenses

Contact lens curing systems and methods are described. A contact lens curing system includes an oven that has a plurality of curing zones, a mold advancement system for moving the contact lens mold assemblies between the plurality of zones, and a controlled atmosphere within the curing zones that provides a substantially chemically inert environment in which contact lens precursor materials can be polymerized in contact lens mold assemblies located in the curing zones. Methods of producing contact lenses include curing contact lens precursor materials in contact lens mold assemblies in the lens curing system. As an example, an oven for curing contact precursor materials in molds, the curing process being done in an inert atmosphere, includes a plurality of heating zones, such as three heating zonesor two heating zonesand a mold advancement system for moving the molds between the plurality of zones, wherein a first zone and second zone of the plurality of zones are maintained at different temperaturesor

Methods of producing silicone hydrogel ophthalmic lenses include contacting one or more delensed silicone hydrogel ophthalmic lens with a liquid composition that contains alcohol, water, and a surfactant. The methods can be steps of an extraction/hydration procedure used in the production of silicone hydrogel contact lenses. In some examples, contacting silicone hydrogel ophthalmic lens products with a liquid composition that contains alcohol, water, and a surfactant can significantly reduce or prevent surface distortion of the ophthalmic lens resulting from the extraction procedure. Some methods include subsequently contacting the silicone hydrogel ophthalmic lens with a liquid composition consisting essentially of water and a surfactant.
