ABSTRACT
Wavefront measurement is a new tool for determination of the visual performance of the eye and for developing a treatment plan to abolish higher-order aberrations to provide supervision for the patient. It is known that laser in situ keratomileusis (LASIK) treatment causes significant increase in higher-order aberrations because of the corneal cut (Krueger RR. Wavefront technology. 1st International LASEK Congress, March 2123,2002, Houston, TX); therefore, attention of the refractive surgeons focuses again to advanced surface ablation techniques such as photorefractive keratectomy (PRK) with sophisticated flying spot laser beam delivery technology and laser intraepithelial keratomileusis (LASEK) (1-5), which seems to be a viable alternative to LASIK technology.
