Abstract

To compare the clinical results of LASIK with that of PRK in moderate myopia, we reviewed clinical outcome of LASIK and PRK for postoperative six months.In the LASIK, the manual microkeratome produced by SCMD and the VISX STAR model laser were used.In the PRK, the same model laser by the same company was used.The number of patients receiving the LASIK was 41 (75 eyes)and that of the PRK was 36 (68 eyes).In a week following the surgery the mean uncorrected visual acuity was 0.8 or better 36 eyes (52%)in the PRK and 54 eyes (70%)in the LASIK respectively (p<0.05).At postoperative three months and six month, the uncorrected visual acuity become stable showing 61 eyes (89%)and 65 eyes (94%)in the PRK and 66 eyes (88%)and 70 eyes (93%)in the LASIK respectively.At postoperative 1 month, the average corneal haziness was grade 1.7 and at postoperative six month, it reduced considerably to 0.6 in average in PRK group but no haziness was detected in the LASIK group.In both groups, the uncorrected visual acuity improved, however the best corrective visual acuity were reduced in four eyes of the PRK group and nine eyes of the LASIK group.From the above results, it is concluded that there is no significant difference between the outcome of PRK and LASIK in moderate myopia.
