Research Article: The Accuracy of Flap Thickness and Diameter in LASIK Using a Femtosecond Laser
Introduction:
Laser in situ keratomileusis (LASIK) is one of the most common refractive procedures performed worldwide. By reshaping the cornea, it can be used to correct myopia, hyperopia, and astigmatism. However, for successful LASIK outcomes, the flap must be created in a safe and predictable manner. First, the achieved flap thickness must be very close to target thickness. A flap that is too thick may compromise the residual stroma and increase the risk for corneal ectasia. A flap that is too thin may lead to corneal haze,…
