Two-year Follow-up of Eyes Without Topical Corticosteroid Treatment After Photorefractive Keratectomy (PRK)

This study was performed to evaluate the result of photorefractive keratectomy (PRK) without topical corticosteroid treatment at postoperative two years. PRK was performed by Summit OmniMed™ excimer laser, using a 5.0 mm ablation zone in 51 eyes of 29 patients who were then followed up for more than 2 years. During this period, patients who showed myopic regression of less than 1.5 diopters(D) or corneal haze less than grade 2, were regarded as the favorable result group and those who showed myopic regression equal to or greater than 1.5 D or corneal haze greater than grade 1 were regarded as the unfavorable result group.
