Assessment of Refractive and Topographic Outcome of LASIK Using Customized Femtosecond Flap for Astigmatic Patients
Purpose
To evaluate the refractive outcome and topographic changes after LASIK with femtosecond oval flaps.
Methods
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.
Results
The procedure effectively corrected the refractive error with 0% of eyes lost any line. Follow-up mean was 6 months (3 to 12).
Conclusion
The idea of oval flap designs appears to be safe and effective alternative to rounded flaps.
