1522401 Pseudophakes L FLOM and K J RODGERSON 2 Feb 1976 [14 Feb 1975, 14 Jan 1976] 04045/76 Heading A5R A pseudophakos comprises a lens 10, a lens retaining member 30 and posts 12, 14 which extend between and connect the lens and retaining member. The retaining member may be a ring, a part ring, diametrically opposed arcuate members or buttons and may be snap-fitted or welded to the posts. In one embodiment of an instrument for placing the pseudophakos, Fig. 13, the retaining member 30 is releasably gripped between opposed grooves provided in a projecting finger 123 and a clamp 125 at the end of a manually reciprocable arm 131 attached to the instrument handle 121. The lens 10 is supported, e.g. by a generally triangular wire bridle 147, 148 at the end of a barrel 135 which is movable by adjusting nut 136. The lens can thereby be moved relative to the retaining member to snapfit the posts 13, 14 into the latter.
