Claim:
A method for treating an ophthalmic disease, disorder, or injury in a mammal, the method comprising administering to the mammal in need of such treatment a matrix controlled diffusion drug delivery system comprising a therapeutically effective amount of one or more pharmaceutically active agents entrapped in a polymerization product of a monomeric mixture comprising one or more silicon-containing monomers of Formula I: wherein L can be the same or different and is selected from the group consisting of urethanes, carbonates, carbamates, carboxyl ureidos, sulfonyls, a straight or branched, substituted or unsubstituted C1-C30 alkyl group, a C1-C30 fluoroalkyl group, a substituted or unsubstituted C1-C20 ester group, an alkyl ether, cycloalkyl ether, cycloalkenyl ether, aryl ether, arylalkyl ether, a polyether containing group, an ureido group, an amide group, an amine group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C3-C30 cycloalkylalkyl group, a substituted or unsubstituted C3-C30 cycloalkenyl group, a substituted or unsubstituted C5-C30 aryl group, a substituted or unsubstituted C5-C30 arylalkyl group, a substituted or unsubstituted C5-C30 heteroaryl group, substituted or unsubstituted C3-C30 heterocyclic ring, a substituted or unsubstituted C4-C30 heterocyclolalkyl group, a substituted or unsubstituted C6-C30 heteroarylalkyl group, a C5-C30 fluoroaryl group, or a hydroxyl substituted alkyl ether and combinations thereof; X− is at least a single charged counter ion; n is an integer from 1 to about 300; R1, R2, R3, R4, R5, R6, R7 and R8 are independently hydrogen, a straight or branched, substituted or unsubstituted C1-C30 alkyl group, a C1-C30 fluoroalkyl group, a C1-C20 ester group, an alkyl ether, cycloalkyl ether, cycloalkenyl ether, aryl ether, arylalkyl ether, a polyether containing group, an ureido group, an amide group, an amine group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C3-C30 cycloalkylalkyl group, a substituted or unsubstituted C3-C30 cycloalkenyl group, a substituted or unsubstituted C5-C30 aryl group, a substituted or unsubstituted C5-C30 arylalkyl group, a substituted or unsubstituted C5-C30 heteroaryl group, a substituted or unsubstituted C3-C30 heterocyclic ring, a substituted or unsubstituted C4-C30 heterocyclolalkyl group, a substituted or unsubstituted C6-C30 heteroarylalkyl group, fluorine, a C5-C30 fluoroaryl group, or a hydroxyl group, and V is independently a polymerizable ethylenically unsaturated organic radical.
