Patent number: 6352343Abstract: Gas-permeable hard contact lenses are produced by hot press-stretching a crosslined gas-permeable hard contact lens material and then machining the press-stretched material. The gas-permeable hard contact lenses are formed from a crosslinked gas permeable hard contact lens material which is hot press-stretched to have a compression ration of 5 to 50% and a compression-flexure fracture strength of 300 to 1,500 g. Efficiently produced gas-permeable hard contact lenses are produced which are free of optical strains, excellent in transparency, small internal stress and comfortable to wear with improved durability strength.Type: GrantFiled: January 14, 2000Date of Patent: March 5, 2002Assignee: Hoya Healthcare CorporationInventors: Kikuo Mitomo, Tohru Shirafuji, Hideo Suda, Teruhisa Shimizu, Yuichi Yokoyama
