Abstract Details


To assess the efficacy and stability after Laser-Assisted Subepithelial Keratomileusis (LASEK) in patient with preceded Radial Keratotomy (RK) .


St. Petka Eye Clinic ,Varna, Bulgaria 01.2003 – 12.2015


A retrospective study was performed. The analysis includes 22 patients ( 37 eyes) , 11 women and 11 men (age 42 to 64) . Non of them had any other ocular pathology. The LASEK procedure was performed with Schwind Amaris Ecximer laser. Corneal shape was evaluated with Orbscan Corneal Topographer estimating average keratometry values before and on the 1st, 3th and the 6th month following the procedure. Distance UCVA and BCVA before and after LASEK was measured with the Snellen Chart .


Efficacy of the refractive procedure is measured with the difference in preoperative and postoperative UCVA, as well as the change in the keratometry .Mean preoperative Visual acuity is 0,20 (Ranging from 0,01 to 0.8) .Mean postoperative Visual acuity is 0,83 ( Ranging from 0.2 to 1.0 ) .Stability is measured by difference in average K readings postoperatively in the 1st , 3th and 6th month following the procedure. The change of mean postoperative K in 3th month is about 0.22 D. The change of mean postoperative K in 6th month is about 0.21 D . As a measure of clinical significant regress we assume change of postoperative K >0,80.40 % of patients have refractive regress


LASEK after RK is effective and stable (improvement in postoperative UCVA is up to 0.50). Mean postoperative Keratometry change is less than 1 D at 6th month (0,20). The precise interpretation of the data shows a big amount of patients with refractive regress (average K change >0,80 in 40% percent of researched eyes)
