Patent number: 8870371Abstract: Provided is a colored contact lens in which a colored band is disposed at a boundary part between a dark part and a white part of an eye, and a density is gradually changed from the dark part to the white part of the eye such that the density of this colored band decreases from an inner circumference side to an outer circumference side. As a result, a novel colored contact lens is provided with which it is possible to bring out beauty of the white part of the eye, which has been ignored by conventional technology, while an impression is maintained that is as natural and elegant as possible by avoiding an artificial impression such as that found in conventional technology.Type: GrantFiled: June 17, 2011Date of Patent: October 28, 2014Assignee: Menicon Co., Ltd.Inventors: Ichiro Ando, Yuji Goto, Ryo Matsushita, Kazuharu Niwa

Patent number: 8662663Abstract: The present invention provides a hybrid soft contact lens including a central portion formed with a first hydrous soft material, and a peripheral portion formed with a second hydrous soft material, in which the first hydrous soft material is obtained by curing a first curable composition including a silicone-containing monomer. Preferably, the first hydrous soft material has a Young's modulus of no less than 3.0 MPa and no greater than 100 MPa, and the second hydrous soft material has a Young's modulus of no less than 0.20 MPa and less than 3.0 MPa.Type: GrantFiled: July 5, 2010Date of Patent: March 4, 2014Assignee: Menicon Co., Ltd.Inventors: Ryo Matsushita, Koji Otani, Kazuharu Niwa, Kazuhiko Nakada

Patent number: 8523878Abstract: A method of producing a medical instrument whereby a highly hydrophilic and lubricant coating layer having a high durability can be formed by a simple technique and thus highly hydrophilic and lubricant properties can be imparted to a surface of a medical instrument. An intraocular lens insertion instrument having been subjected to a surface treatment as described above is also provided. The method includes preparing a coating solution by mixing at least a water-insoluble polymer having carboxyl group and a polyfunctional reactive compound with an organic solvent; applying this solution on the surface of the medical instrument; conducting crosslinking; and performing a chemical reaction process. The coating layer is made hydrophilic. The intraocular lens insertion instrument is made hydrophilic by forming the coating layer as described above on an inner surface of an insertion tube portion, crosslinking and then performing the chemical reaction process.Type: GrantFiled: December 17, 2008Date of Patent: September 3, 2013Assignee: Kowa Company, Ltd.Inventors: Kohsuke Satake, Kazuharu Niwa, Ryo Matsushita, Yasuhiko Suzuki, Hiroko Nomura, Kazuhiko Nakada
