PRESENT TREND OF HYDROGEL MATERALS AS INTRAOCULAR LENS.

The need for artificial intraocular lens to substitute the physiological lens removed due to cataract formation, has been recognized over thirty years. At present over 80% of cataract removal is accompanied with artificial lens implantation. PMMA was and is still the major plastic material used to make intraocular lens for implantation. A new approach using hydrogel material for an intraocular lens is presented, its qualities and advantages are documented by lab experiments and lately by human implantations. For fifteen months these lenses has been used in humans with excellent results. There were no eye reactions to the material using the standard measurement of Tyndall effect or synechiae formation. Visual results were good minus 20/20 to 20/30 in all cases. Due to low reflection factor of the lens surface, no glare was experienced by these patients. The diameter of the lens length would determine its location in the eye. The long-run experience proved, in the bag fixation, as safe and long standing with no movements or luxation of the lens.
