ABSTRACT:
An optical section of an intraocular lens has a pair of spaced apart threaded recesses which are threadingly locked to threaded shank sections of an iris retention loop. The shank sections are integrally joined to such loop so each shank section acts as an anchor preventing a screwing movement of the other shank relative to the optical section. A method is described of expanding a shank section of a lens retention member in situ within a threaded or other undercut recess of an optical section of an intraocular lens.
