The aim of the study is to evaluate the severity of dry eye syndrome following excimer laser vision correction using no-touch all-laser photorefractive keratectomy in comparison to conventional lasik
Prospective interventional clinical study 2 groups: Group A : 20 eyes of 10 patients undergoing transepithelial PRK Group B: 20 eyes of 10 patients undergoing LASIK using mechanical microkeratome Tear Break Up Time and Schirmer 2 tests are used to evaluate severity of dry eye before surgery and 1 , 3 and 6 months postoperative Follow up period : 6 months
