Ultra-short pulse (femtosecond) laser surgery: initial use in LASIK flap creation.

Abstract

The highly localized tissue effects of low energy femtosecond duration (ultrashort) laser pulses may be used to create three-dimensional intrastromal resections with micron precision and minimized collateral tissue damage. A surgical laser system that produces and delivers such pulses has been developed and tested clinically for creation of a corneal flap in LASIK. Expanded evaluation of this technology in this and additional keratorefractive applications is currently underway.
