Abstract
A polymeric composite including (1) a substrate formed of a moldable polymer; (2) a first polymeric layer containing a base polymer, the first layer adhering to a surface of the substrate by physical entrapment of at least some molecules of the base polymer in the substrate; and (3) a second polymeric layer containing a hydrophilic polymer, the second layer adhering to a surface of the first layer by physical entrapment of at least some molecules of the hydrophilic polymer in the first layer. Also disclosed is a device including such a composite for delivering an intraocular lens.
