groups of 20, were retrospectively reviewed. All patients had RK using the American technique. Emmetropia was the goal in all patients. Groups were compared with respect to preoperative refractive status, age, sex, and outcome. Outcomes analysis included visual acuity, refractive error, complications, and enhancement rates. Data were reviewed preoperatively and 1 and 3 months postoperatively. The outcomes of this surgery probably are documented best by the Prospective Evaluation of Radial Keratotomy (PERK) study and its follow-up papers over the years. The year follow-up PERK study results confirmed that RK reduced myopia but that the effectiveness of the outcome varied among patients.
