Paper Abstract

Refractive changes can be induced through modification of the anterior corneal surface. A method using an ultrashort pulsed infrared laser (Nd:YLF) and resulting in an intrastromal photoablation has been reported for that purpose. In this concept a well defined stromal volume is ablated or vaporized. After collapse of the bubbles that have been produced, the anterior surface of the cornea should flatten, leading to a lower myopic refraction of the eye. It has already been shown that there is less collateral tissue damage associated with picosecond than with nanosecond laser pulses. In this study, the acute and long term morphological as well as thermal effects of intrastromally applied picosecond laser pulses are investigated.
