We focus on bioanalogic functional replacements of human eye structures or tissues, such as the crystalline lens or the vitreous body. We develop new hydrogel technologies to produce bioanalogic implants, which are very similar to native structures and tissues in their shape, optical qualities and material properties. We also investigate topics in visual and physiological optics (e.g., accommodation, polyfocality, contrast sensitivity, natural crystalline lens properties, etc.), biocompatibility of materials (cytotoxicity, cell growth, calcification) and transport processes within the eye. We take particular interest in intraocular lens (IOL) design, where we follow the bioanalogic approach.
