Process for producing surface-treated intraocular lens and intraocular lens capable of inhibiting secondary cataract
Provided are a process for producing an intraocular lens capable of inhibiting secondary cataract that may occur after the insertion of an intraocular lens and a secondary-cataract-inhibiting intraocular lens obtained by the above process, and the process is for producing a surface-treated intraocular lens, which comprises irradiating the surface of an intraocular lens with active light that works to decompose oxygen molecules to generate ozone and that also works to decompose the ozone to generate active oxygen, in the presence of oxygen, and the lens is a secondary-cataract-inhibiting intraocular lens obtained by the above process.
1. A process for producing a surface-treated intraocular lens that inhibits secondary cataract, which comprises irradiating the surface of an intraocular lens with active light having emission peaks at a wavelength region of 185±5 nm and a wavelength region of 254±5 nm both at the same time that works to decompose oxygen molecules to generate ozone and that also works to decompose the ozone to generate active oxygen, in the presence of oxygen.
2. The process of claim 1 , wherein the intraocular lens is a soft lens.
3. The process of claim 2 , wherein the soft lens is formed of a soft acrylic material.
4. The process of claim 1 , wherein the intraocular lens has an optic portion formed of a hard lens.
