Patent ID: 7138471

Claim:
A method of treating presbyopia by removing a patient's lens from the lens capsule bag via an incision in the cornea, injecting into the lens capsule bag a macromonomer of Formula I, and polymerising the macromonomer to a polymer, Formula I being: where: m=an integer≧1 n=an integer≧1 r=an integer≧1 A is a non-reacted moiety resulting from the addition polymerisation of ethylenically unsaturated monomers, B is a moiety resulting from the additional polymerisation of ethylenically unsaturated groups that possess hydroxyl or amino groups bound to the ethylenically unsaturated groups via a carbonyl group and has the following structure: C has the following structure: where: R=H, Me X=O, NH Z=is optional and is O, NH, NR, S, CO 2 where R is C 1 –C 8 alkyl, and W=is optional and is linear, branched cyclic hydrocarbyl chains, polyether chains or heterochains, linear or cyclic.
