摘要： 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 comprises the steps of: 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 whereby 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.

摘要： 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.
