摘要 |
A soft and elastic intracameral lens, the back surface of which is formed by a continuous rotation-symmetric convex surface and the front surface comprises a central convex surface of sphere or quadric rotation-symmetric body linked on the diameter of 4 to 8 mm, preferably through a rounded transition, to a concave ring surface of a sphere or a toroid, whereas the distance between the concave ring surface and the back surface is 0.05 to 1.5 mm. The intracameral lens according to the invention is manufactured by charging a mold, which has the negative shape of the required front surface of the lens and is provided at the periphery with a sharp edge protruding by 0.05 to 1.5 mm above the end of the peripheral ring surface, with a monomer mixture as high as above the sharp edge to form a continuous convex meniscus and the mold with the monomer mixture is then exposed to polymerization conditions. |
