A method of designing a fluid-filled contact lens () is described. The method involves generating a computational model that includes a fluid-filled lens () and the shape of a cornea causes deformation of an internal structure of the fluid-filled lens () to generate a deformed, fluid-filled lens () with altered optical properties. The method also includes modelling () the optical properties of the deformed, fluid-filled lens (). The shape of the fluid-filled lens () is then adjusted () to reduce the effects of the deformation on the optical properties. This is referred to as an adjusted fluid-filled lens (). A corresponding off-eye lens design is generated (based on the adjusted fluid-filled lens design.

The present disclosure concerns a tuneable ophthalmic lens. The tuneable ophthalmic lens comprises an activated state and a deactivated state. The ophthalmic lens further comprises a central chamber. The ophthalmic lens also comprises a fluid reservoir, the fluid reservoir being in fluid communication with the central chamber. The fluid reservoir comprises a pump for pumping fluid between the fluid reservoir and the central chamber. In the deactivated state the central chamber is substantially empty of fluid. In the activated state the central chamber is not substantially empty of fluid.

A medical device including a pre-defined space such as a geometric shape or void. In one approach, the pre-defined space provides desired rigidity and more comfort for a user. There is also provided an approach which enables engravings and accommodates electronics, mechanical objects, or other rigid or unique shapes to be embedded within a medical device such as a contact lens. When adapted to swellable substrates, the resulting swelled material can leave a gap around a perimeter of embedded structure.

A silicone elastomer-hydrogel hybrid contact lens includes a silicone elastomer layer and a hydrogel layer adhered to the silicone elastomer layer by a delamination-resistant bond that is formed by an elastomer-swellable monomer that is included in the polymerizable composition used to form the hydrogel layer.

A silicone elastomer-silicone hydrogel hybrid contact lens comprises a silicone elastomer layer adhered to silicone hydrogel layer by a delamination-resistant bond. The silicone hydrogel layer has a percent swell of about &#x2212;5% up to about 20%. The silicone elastomer layer may have one or more objects embedded within it or adhered to its surface. Such objects may include variable-focus lenses and/or electronic components.

A method for manufacturing a silicone hydrogel contact lens is described that comprises curing a polymerizable composition comprising at least one siloxane monomer and at least one hydrophilic vinyl-containing monomer in a contact lens mold comprising a molding surface having a coating comprising a hydrophilic polymer. The hydrophilic coating is not solubilized by the polymerizable composition during the curing step. The resulting polymeric lens body is removed from the mold, washed to remove any of the hydrophilic polymer that may have transferred from the mold surface to the lens during the curing or lens removal process, and packaged to provide a silicone hydrogel contact lens having a contact angle that is lower than what it would otherwise be had the lens been cured in the same contact lens mold lacking the hydrophilic coating.
