Intraocular Lenses come in a variety of materials and designs. Your surgeon generally chooses a lens made of a material that is best suited to your individual situation. All intraocular lenses used in our practice are coated with UV filters. Some lenses are yellow in color. These lenses are theoretically better at blocking the light rays in the blue spectrum which are thought to be related to the development of macular degeneration in some patients. Some intraocular lenses are designed to be multifocal in certain lighting circumstances, which may enable patients to see both at distance and near without the aid of spectacles.
This effect has been shown in all patients in whom the lens has been implanted, and it is once again important for patients to realize that while cataract surgerywith intraocular lens implantation frequently results in a reduced dependency on eye glasses it is never guaranteed to eliminate this need totally.
