Patent ID: 8444408

Claim:
A device for manufacturing an implantable planar/convex, biconvex, planar/concave or convex/concave lens made from a liquid polymer precursor, comprising: a one-piece, open mold, the mold comprising an open concave cavity, delineated by a functional shaping inner surface being unwettable or incompletely wettable by a liquid precursor and ending by a peripheral sharp edge having the shape of a circle which lies in the plane perpendicular to the vertical axis of the open concave cavity and has a diameter of 5 to 10 mm; wherein the radius of curvature of the open concave cavity increases from the lowest value in the proximity of the vertical axis of the open concave cavity in the direction towards the peripheral sharp edge of the open concave cavity; and wherein the open concave cavity passes in the top part of the open mold over an intermediate circular edge having the shape of a circle lying in the plane parallel to the plane of the peripheral sharp edge into a transitional open cylindrical or frustum-of-a-cone cavity delineated between the peripheral sharp edge and the intermediate circular edge, wherein the transitional open cylinder or frustrum-of-a-cone cavity defines a planar surface at an angle α2 less than or equal to 90°; and a means for rotating the mold.
