Abstract

The polymer material is a mixture, consisting substantially of: oligourethanemethacrylate having the following structural formula: ##STR1## taken in ratio that ensure the ability of the mixture to light curing under the effect of UV radiation. The intraocular lens comprises an optic and a supporting portion, both made substantially of the mentioned polymer material. The method for making the mentioned lens consists in that the liquid mentioned polymer material is filled in the half-molds of a casting mold and the half-molds themselves are shaped as cylinders provided with recesses made on the inner end surfaces thereof, which recesses form the lens optic portion after joining the two half-molds together; a pattern is provided on the inner surface of one of the half-molds, including areas transparent to UV radiation and those opaque thereto, a negative image of the pattern corresponding to a two-dimensional image of the lens optic portion and of its supporting portion; a similar pattern is provided on the inner surface of the other half-mold, a negative image of the pattern corresponding to the image of the lens optic portion alone; the casting mold is irradiated with a focused UV radiation in two stages.
