The present invention provides a material for intraocular lens which has improved hydrolysis resistance. The material for intraocular lens according to the present invention is obtained by polymerizing a monomer composition comprising: a base monomer, a hydrophilic monomer, and a cross-likable monomer, wherein the base monomer comprises an aromatic ring-containing acrylate monomer and an alkoxyalkyl methacrylate monomer having an alkoxyalkyl group having four or less carbon atoms. A blending ratio on a molar basis of the methacrylate monomer with respect to the acrylate monomer in all the monomer components contained in the monomer composition is 0.25 to 1.00.

Fouling on the surface of biomaterials and medical devices by proteins and microorganisms in the body severely hinders device functionality and drastically shortens lifetime. Currently, there is high demand for coatings that mitigate this biofouling. In this invention, the use of polyacrylamides has been explored in hydrogel coatings by building the largest library of acrylamide-based copolymer anti-biofouling hydrogels (>160 combinations) to date. A combinatorial approach was used, exploiting the ease of hydrogel synthesis to examine a high-throughput screening of platelet adhesion, precursor to thrombosis and a common culprit in biofouling. Applicability has been demonstrated of top-performing polyacrylamide-based hydrogel by (i) coating affinity-based electrochemical biosensors in vitro in a whole blood assay, and (ii) through coating an electrochemical aptamer-based device for real-time monitoring of analytes in an in vivo closed-loop system.

An intraluminal endoprosthesis such as a stent has a metallic supporting structure and a sleeve surrounding the supporting structure. The sleeve can include fibres which are applied to an outer side of the supporting structure. The fibres each have a polymer core and a hydrogel casing connected thereto. The sleeve can also be formed from a fibre mixture of polymer and hydrogel fibres.

Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
