Abstract

The most probable reason for presbyopia, the age-related loss of the accomodation-ability of the eye, is an age-related loss of the elasticity of the lens. To increase the elasticity, resp. regain elasticity we performed different fs-laser-induced cuts with an near-infrared 5 kHz femtosecond laser inside ex-vivo and in-vivo rabbit lenses. Sagittal and annulus cutting patterns in the lens were produced by focusing the laser beam through the cornea inside the lens and creating a laser induced optical breakdown. The cutting results were recorded with light microscopy and finally, after euthanization, changes in the optical fibers of the lens tissue were described.
