Abstract
Disclosed herein are surface treatments for soft silicone gel materials such as silicone intraocular lenses.
Claims33
A surface treated intraocular lens, comprising:
- a) the product of a reaction mixture comprising a platinum catalyst, a silicon-hydride cross-linker, and a polymer having formula (I):
- wherein:
- the sum of m and n is x;
- x is from 0 to about 5000;
- y is from 0 to about 500;
- z is from 0 to about 500;
- the sum of x, y, and z is at least 1;
- R1-R8 are each independently selected from the group consisting of hydrogen, —CH3, —C6H5 and —CH═CH2;
- wherein at least one of R1, R2 and R3 is —CH═CH2;
- wherein at least one of R6, R7, or R8 is —CH═CH2;
- and
- b) a surface treatment consisting essentially of a compound comprising at least one Si—H bond.

A method for manufacturing a surface treated intraocular lens, comprising:
- a) providing a reaction mixture comprising:
- (i) a polymer having formula (I):
- wherein:
- the sum of m and n is x;
- x is from 0 to about 5000;
- y is from 0 to about 500;
- z is from 0 to about 500;
- the sum of x, y, and z is at least 1;

- wherein at least one of R1, R2 and R3 is —CH═CH2;
- wherein at least one of R6, R7, or R8 is —CH═CH2;
- (ii) a silicon hydride cross-linker;
- and
- (iii) a platinum catalyst;
- b) curing the reaction mixture to provide a cured silicone material;
- c) surface treating the cured silicone material with a surface treatment composition consisting essentially of a compound comprising at least one Si—H bond to provide a surface treated silicone material;
- and
- d) drying the surface treated silicone material to provide the surface treated intraocular lens.
