Abstract

This invention relates to comfortable ophthalmic devices and methods of producing such devices.

First claim

1 - 58 . (canceled)

59 . An ocular device prepared by treating a polymerized ophthalmic lens with a wetting agent, provided that the ophthalmic lens formulation does not comprise said wetting agent prior to its polymerizaiton.

60 . The device of claim 59 wherein treating comprises heating the polymerized ophthalmic lens in a packaging solution to a temperature of about greater than 50° C. to about 150° C.

61 . The device of claim 59 , wherein the wetting agent is selected from the group consisting of polyvinylpyrrolidone, graft co-polymers of polyvinylpyrrolidone, and co-polymers of polyvinylpyrrolidone.

62 . The device of claim 59 wherein the wetting agent is polyvinylpyrrolidone having a K-value of about K-60 to about K-90.

63 . The device claim 59 wherein the ophthalmic lens is selected from the group consisting of acofilcon A, alofilcon A, alphafilcon A, amifilcon A, astifilcon A, atalafilcon A, balafilcon A, bisfilcon A, bufilcon A, comfilcon, crofilcon A, cyclofilcon A, darfilcon A, deltafilcon A, deltafilcon B, dimefilcon A, drooxifilcon A, epsifilcon A, esterifilcon A, etafilcon A, focofilcon A, genfilcon A, govafilcon A, hefilcon A, hefilcon B, hefilcon D, hilafilcon A, hilafilcon B, hioxifilcon B, hioxifilcon C, hixoifilcon A, hydrofilcon A, lenefilcon A, licryfilcon A, licryfilcon B, lidofilcon A, lidofilcon B, lotrafilcon A, lotrafilcon B, mafilcon A, mesifilcon A, methafilcon B, mipafilcon A, nelfilcon A, netrafilcon A, ocufilcon A, ocufilcon B, ocufilcon C, ocufilcon D, ocufilcon E, ofilcon A, omafilcon A, oxyfilcon A, pentafilcon A, perfilcon A, pevafilcon A, phemfilcon A, polymacon, silafilcon A, siloxyfilcon A, tefilcon A, tetrafilcon A, trifilcon A, and xylofilcon A.

64 . The device of claim 59 wherein the ophthalmic lens is selected from the group consisting of genfilcon A, lenefilcon A, lotrafilcon A, lotrafilcon B, balifilcon A, comfilcon, etafilcon A, nelfilcon A, hilafilcon, and polymacon.

65 . The device of claim 59 wherein the ophthalmic lens is etafilcon A.
