We recently started performing radial keratotomy (RK) at Hyderabad, Sindh, Pakistan, and report here the results of RK on 52 eyes of 26 patients, 10 men and 16 women, ranging in age from 18 to 46. The follow-up period was two years for all the patients. Based on the refractive error, we divided the patients into two groups: Group A (30 eyes) with preoperative spherical equivalent myopia varying from -1.50 D. to -3.00 D. and Group B (22 eyes) with this amount varying from -3.25 D. to -7.00 D. In Group A, 20 eyes (66.6%) were corrected fully, eight eyes (26.6%) were slightly under corrected, and two eyes (6.6%) were over-corrected by +0.50 D. In Group B, all patients were left with residual myopia of -1.00 D. to 1.50 D. The change in astigmatism ranged from a decrease of -1.00 D. cylinder in the preexisting refractive error to to an appearance of new -0.50 D. cylinder. Although no serious complications occurred, in five eyes (9.6%) selfsealing microperforation occurred on the operating table. Interestingly, all of these were the eyes of contact lens wearers. The post-RK uncorrected visual acuity was 6/12 or better in 90.62% (47) of the eyes.
