LASIK Flap Thickness Accuracy after Using Femtosecond Laser, AYA H. FARAG, RANIA M. SOBHY, MOHAMED H. HOSNY and MAHMOUD H. ABOSTEIT
Abstract
Aim of Work: Was to measure the flap thickness accuracy after using the femtosecond laser in LASIK surgery.
Setting: Tertiary Ophthalmic Referral Centre, Cairo, Egypt.
Design: This prospective study was carried out in a private hospital for 20 eyes of 10 myopic patients with a refractive error ranging from –1D to –9D, with astigmatism up to 4D.
Method: All patients underwent surgery under topical anaesthesia, all surgeries were done by the same surgeon, and the flap thickness was measured in the center, and 2mm nasal and temporal to the center, 1 month after surgery using anterior segment OCT.
Result: In our study the predictability of flap thickness was significantly high in the femtosecond created flaps, the mean central flap thickness was 101mm±1.2SD (ranging from 100mm to 104mm), the mean flap thickness at 2mm nasal to the center was 105.27mm±2.7 (ranging from 101mm to 109mm), the mean flap thickness 2mm temporal to the center was 104.56m±1.98 (ranging from 101mm to 107mm), the mean flap thickness was 103.63mm±1.77SD (ranging from 101mm to 106mm).
Conclusion: Lasik flaps created with femtosecond are predictable, accurate and uniform.
