Paper Abstract

Transparency of the lens is essential to optimal visual acuity. About 90% of people above 65 years of age have some degree of lens opacity. Many of them have sufficiently dense opacities to necessitate a cataract extraction. With age the lens nucleus becomes increasingly yellow and the lens color may even become brown. Scattering within the nucleus also decreases the transparency of the lens , thereby disturbing vision (cataract) . The removal of the cataractous lens is often performed using ultrasounds (phacoemulsification) , providedthe lens is not too hard. The use of lasers can also be considered. The ability of the picosecond Nd:YLF laser is investigated with an eye model dedicated to this purpose.
