Applanation-free femtosecond laser processing of the cornea.

A novel approach for applanation-free femtosecond refractive surgery with the help of a contact liquid layer is presented. A laboratory device for performing corneal procedures is described based on a femtosecond-laser system which has been tested and evaluated by processing ex vivo pig eyes. With its help, flap cuttings for different flap thicknesses were performed.

Laser Vitreolysis. A review.

Strands and vitreous adhesion bands can either be dissected noninvasively, transpupillarily by photodisruptive pulses of a Nd:YAG laser, operated in the photodisruptive mode, or invasively using an Er:YAG laser and specialized fibers. The previously used CO(2), Ho:YAG, and ultraviolet lasers have become less popular in the recent past. When using the transpupillary method, specialized contact lenses are required.
