Abstract

Claims (22)

1 . A method of manufacturing at least one of a haptic and an optic portion of an intraocular lens, comprising:

combining a plurality of monomers with an additional monomer comprising a hydroxyl moiety so as to create a pre-polymer, wherein the plurality of monomers comprise butyl acrylate, trifluoroethyl methacrylate, and phenylethyl acrylate;

creating a cross-linkable polymer from the pre-polymer by converting the hydroxyl moiety into a cross-linkable methacrylate; and

curing the cross-linkable polymer to form at least one of the haptic and the optic portion of the intraocular lens.

2 . The method of claim 1 , wherein the additional monomer comprising the hydroxyl moiety is hydroxyethyl acrylate (HEA).

3 . The method of claim 1 , wherein the additional monomer comprising the hydroxyl moiety is hydroxyethyl methacrylate (HEMA).

4 . The method of claim 1 , wherein the additional monomer comprising the hydroxyl moiety is hydroxybutyl acrylate (HBA).

5 . The method of claim 1 , wherein the additional monomer comprising the hydroxyl moiety is added to reduce water-induced haze or glistening.

6 . The method of claim 1 , wherein the curing involves UV curing in the presence of a photoinitiator.

7 . A method of manufacturing an intraocular lens, comprising:

forming a first body and a second body of the intraocular lens;

applying an adhesive between the first body and the second body, wherein the adhesive comprises:

a first primary component present in the adhesive in an amount between 55% to 75%, wherein the first primary component comprises:

trifluoroethyl methacrylate;

at least one of butyl acrylate and n-butyl methacrylate; and

at least one of phenylethyl acrylate and phenylethyl methacrylate, and

a second primary component present in the adhesive in an amount between 23% to 43%, wherein the second primary component is a reactive acrylic monomer diluent; and

adhering the first body to the second body by curing the adhesive.

8 . The method of claim 7 , wherein applying the adhesive further comprises applying the adhesive along a circular raised periphery of a posterior element of the intraocular lens, and wherein the adhesive is used to adhere the posterior element to an anterior element of the intraocular lens.

9 . The method of claim 7 , wherein the first primary component is a cross-linkable polymer that is not yet cross-linked, and wherein the cross-linkable polymer is too bulky to migrate into either the first body or the second body.

10 . The method of claim 7 , wherein the reactive acrylic monomer diluent is 1-adamantyl methacrylate (ADMA).

11 . The method of claim 7 , wherein the butyl acrylate or the n-butyl methacrylate is between 35% to 45% of the first component, wherein the phenylethyl acrylate or the phenylethyl methacrylate is between 20% to 40% of the first component, and wherein the trifluoroethyl methacrylate is between 15% to 30% of the first component.
