Abstract
The femtosecond laser has potentially improved the safety and precision of creating corneal flaps in laser in situ keratomileusis (LASIK). This review focuses on recent advances in applying femtosecond laser technology to other corneal procedures. The femtosecond laser is capable of cutting tissue at various depths and patterns with minimal collateral tissue injury. The laser can now be used to perform corneal pockets for ring segments, arcuate wedge-shaped resection in correction of high astigmatism, lamellar dissections in anterior lamellar keratoplasty, donor tissue preparation in Descemet's stripping endothelial keratoplasty, and shaped full-thickness keratoplasty. Femtosecond laser-assisted corneal surgery may provide a more precise and safer approach to corneal surgery.
