  • Flexible intraocular lenses made from high refractive index polymers
    Patent number: 5433746
    Abstract: High refractive index copolymers comprised of monomers having the formula: ##STR1## wherein X is H or CH.sub.3 ;m is 0-10;Y is nothing, O, S, or NR wherein R is H, CH.sub.3, C.sub.n H.sub.2n+1 (n=1-10) iso OC.sub.3 H.sub.7, C.sub.6 H.sub.5, or CH.sub.2 C.sub.6 H.sub.5 ;Ar is an aromatic ring which is unsubstituted or substituted with H, CH.sub.3, C.sub.2 H.sub.5, n--C.sub.3 H.sub.7, iso--C.sub.3 H.sub.7, OCH.sub.3, C.sub.6 H.sub.11, Cl Br, C.sub.6 H.sub.5 or CH.sub.2 C.sub.6 H.sub.5 ; and n is 1-5;a cross linking monomer having a plurality of polymerizable ethylenically unsaturated groups are disclosed. Intraocular lenses made of the copolymers which can be inserted into an aphakic eye through a relatively small incision are also disclosed.
