Abstract
Excimer laser in situ keratomileusis was done in 97 eyes of 59 patients to correct moderate and high myopia. Mean follow-up was 150 days. Mean preoperative myopia was -10.75 diopters (D). Mean reduction in myopia was -11.281 D (106.98%) at 1 month and -10.37D (98.417%) at 3 months. At 1-month, 41 eyes (42.27%) had a refraction within -1.00 D and 70 teeyes (72.16%) had a refraction within -2.00 D. At 3 months, 41 eyes (46.59% of 88 eyes) had a refraction within -1.00 D and 66 eyes (75% of 88 eyes) had a refraction within -2.00 D. Mean preoperative keratometric power was 44.00 D; mean postoperative keratometric power was 36.39 D. The keratometric change in power was 7.61 D. Preoperatively, 73 eyes (75%) had a spectacle corrected visual acuity of 20/40 or better; postoperatively, 64 eyes (65.63%) at 1 month and 75 eyes (77.01%) at 3 months reached 20/40 or better. The uncorrected visual acuity was 20/40 or better in 33 eyes (33.72%) at 1 month and in 49 eyes (49.96%) at 3 months. Mean ablation zone diameter was 4.92 mm. Astigmatism was treated separately in 10 eyes. Complications included optical zone decentration (3 eyes with more than 1 mm, epithelial implantation (1 eye), incomplete resection of the disc (2 eyes), severe hypotension, and irregular astigmatism (1 eye).Keywords
