RESUMEN

Regression is one of the complications, which may occur following LASIK eye surgery in high myopic patients. To determine the degree of regression after LASIK in high myopic eyes. This interventional longitudinal study was performed on 34 eyes in 20 patients who underwent LASIK. The range of preoperative refraction errors was -6.12 to -22.00 Diopter. LASIK was performed using Moria microkeratome to create a 9 mm diameter, 160 microns thick flap. Preoperative and four consecutive cycloplegic refractions were carried out using recommended standards. The maximum follow up was after 6 months. Considering all patients, mean preoperative refraction was -10.58 D which decreased to -0.51 +/- 1.33 D a week following surgery. Mean cycloplegic refraction was - 0.98 +/- 1.33 D, -1.21 +/- 1.81 D and -1.42 +/- 1.87 D, respectively, which was recorded at 1,3 and 6 months postoperatively. Maximum regression occurred 6 months after the surgery [0.9 +/- 0.8 D [8.5%]]. Factors associated with regression included preoperative keratometry [P=0.013] and correction rate [P<0.001]. The degree of regression after LASIK in high myopia was related to preoperative keratometry and correction rate
