FLAK Instrument: The Femtosecond Laser (IntraLase Corporation, Irvine, CA) is a focusable infrared laser, similar to the more familiar neodymium-yttrium-aluminum-garnet (YAG) laser, but uses shorter pulses in the hundred-femtosecond (100 X 10-15 seconds) duration range. There is minimal postoperative inflammation and collateral tissue damage.
Subjects: We will be enrolling subjects 18 years or older that need keratoplasty based on clinical findings. Subjects will be enrolled regardless of race or gender on a first come first serve basis. Subjects will be recruited from the physicians own clinic.
PKP Subjects: We will do a retrospective chart review on subjects who have undergone traditional PKP. FLAK eyes will be age and gender matched to these PKP eyes to compare visual outcomes, wound healing and complications.
