ABSTRACT
To prospectively examine the predictability of excimer laser photorefractive keratectomy for compound myopic astigmatism, we treated 107 eyes of 70 patients with a VisX Twenty/Twenty excimer laser and followed them up for 12 months. Patients were divided into three groups with preoperative myopia group 1 with diopters of -6.00 or less, group 2 with diopters between -6.01 and -10.00, and group 3 with diopters greater than -10.00. Also, two groups of patients were evaluated with preoperative astigmatism group I with -2.00 diopters or less and group II with greater than -2.00 diopters. At 12 months group1, with amean preoperative refractive error of -4.332D, changed to -0.19D, group 2 changed from -7.35D to -0.66D, and group 3 changed from -11.72D to -1.23D. Group I with a mean preoperative refractive error of -1.22D changed to -0.55D, while group II changed from -2.63D to -0.77D. Finally, 85% of eyes with preoperative spherical equivalent diopters of -6.00 or less, 65% of eyes between -6.01 and -10.00D, and 42% of eyes greater than -10.00D were corrected within 1D of intended refraction, respectively.
