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.

Abstract: A method of coating a polymeric substrate with a hydrophilic polymer, including (1) applying a base polymer dispersed in a first solvent onto a surface of a substrate formed of a moldable polymer, the first solvent being capable of penetrating into the substrate; (2) removing the first solvent to leave behind on the surface a first polymeric layer, wherein the first layer is formed of the base polymer, at least some molecules of which are partially entrapped in the substrate; (3) applying a hydrophilic polymer dispersed in a second solvent onto the first layer, the second solvent being capable of penetrating into the first layer; and (4) removing the second solvent to leave behind on the first layer a second polymeric layer, wherein the second layer is formed of the hydrophilic polymer, at least some molecules of which are partially entrapped in the first layer. Also disclosed is a coated polymeric substrate prepared by this method.
