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.

Medical device with pre-defined space and related methods

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.

Silicone elastomer-hydrogel hybrid contact lenses

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.

Silicone elastomer-silicone hydrogel hybrid contact lenses

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.
