Abstract: PURPOSE: To facilitate the insertion of an artificial intraocular lens through a small incision in the eye by forming the artificial intraocular lens from a shape memory polymer in which sight assist zone part has a softening temperature in a specific range, a damage temperature, refractive index and an elastically deforming temperature, and which is deformed by heating the same until one of dimensions decreases by a value larger than 20%, and which is returned to its original dimensions by reheating after cooling. CONSTITUTION: A polymer material has a softening temperature Ts of 0 to 42deg. C, a damage temperature Td higher than 42deg.C, and a refractive index higher than 1.39. It is not damaged in an elastic deforming temperature range which is higher than Ts but lower than Td, and accordingly, it can be heated. Butyl methacrylate is cross-linked and polymerized with a small quantity of ethylene glycol dimethacrylate, and the polymer thereof (Ts=20.75deg.C) is processed into a biconvex intraocular lens having a diameter of 6mm. This lens is inserted in a rubber tube having a diameter of 4mm, and is then heated to a temperature of about 60deg.C so that its length is extended to a value which is about 7 times as long as its original value, then the lens is cooled by directly dipping in ice water.  The diameter of the cylinder is about 1.6 mm, so that it can be easily inserted through an incision. When it is heated to 37deg.C in a saline solution, this lens can be returned to a lens having an inherent shape, dimensions and an optical index.
