Nano Laser Photofragmentation
The use of lasers for the fragmentation of the lens in cataract surgery is an interesting alternative to traditional ultrasonic phacoemulsification. Since the beginning of phacoemulsification it has been a constant ambition to reduce the operative trauma and collateral damage of intraocular tissue during phacoemulsification. Parameters to be changed are operating time, total intraocular energy used, incision size, tissue heating, corneal endothelial cell loss and induced corneal astigmatism. During the last years different laser systems have been developed to minimize thermal and mechanical damage of the intraocular tissue [1–3].
