Official title
Changes of Corneal and Total Ocular Higher-Order Aberrations After Conventional LASIK, Femto-LASIK and PRK in Low and Moderate Myopia
Overview
This prospective comparative interventional study will enroll patients with low and moderate myopia who seek laser vision correction at Sohag Center for LASIK and Corneal Surgeries, Sohag, Egypt. Eyes included will be divided into 3 groups according to the type of refractive surgery used (conventional LASIK, Femto-LASIK and PRK) and each group will be subdivided into 2 groups according to the degree of myopia (low and moderate).
