Paper Abstract

Up to now reading glasses are the conventional treatment of presbyopia, an age related effect for every human. According to the Helmholtz theory the reason for the development of accommodative loss is a decreasing elasticity of the lens due to the increasing sclerosis. Since the ciliary muscle and the lens capsule remain active and elastic the whole life, a possible treatment could be the increase of the flexibility by creating gliding planes with fs-laser pulses. flexibility of ex vivo porcine as well as human donor lenses with a laboratory laser system. We will present new results with a compact 100 kHz repetition rate turn key laser system which speeds up the treatment time by a factor of 10. This will offer the opportunity for future clinical trials. Furthermore first in-vivo results on rabbits are presented.
