To evaluate the refractive outcome and topographic changes after LASIK with femtosecond oval flaps.

Twenty eyes (10 patients) suffering from astigmatism/myopic astigmatism underwent femtosecond-assisted LASIK surgery using Alcon /Wavelight FS200 femtosecond laser system and Alcon /Wavelight EX500 excimer laser system. Customized oval flap shape was designed with hinge angle according to the ablation profile and astigmatic axes. Pre- and postoperative refractive outcome and topographic changes were assessed.

The procedure effectively corrected the refractive error with 0% of eyes lost any line. Follow-up mean was 6 months (3 to 12).

The idea of oval flap designs appears to be safe and effective alternative to rounded flaps.
