Abstract
AIM: To observe and compare the effectiveness of excimer laser photorefreactive keratectomy(PRK) and excimer laser in situ keratomeleusis(LASIK) united with PMMA disk in the treatment of hyperopia.METHODS: Forty eyes with hyperopia in 25 patients(16 eyes treated by PRK and 24 eyes treated by LASIK) were corrected by PMMA disk united with bevelled mirror polishing techniques. Dioptry before sursery was from +1.62 to + 6. 25D. The dioptry and visual acuity were compared between both techniques.RESULTS: A 12-month follow-up was performed. There were 2 eyes (12. 5% ) in PRK and 3 eyes(12.5% ) in LASIK group lost above 2 lines of the optimized corrected distance visual acuity. There were 1 eye(6.3% ) in PRK and 2 eyes(8.3% ) in LASIK group lost above 2 lines of the optimized corrected visual acuity at reading distance. The mean uncorrected distance visual acuity of PRK group was 0. 55, and LASIK group was 0. 68; and the mean uncorrected visual acuity at reading distance of PRK group was 0.66and LASIK group was 0. 85. There were 12 eyes(75% ) in PRK group and 20 eyes(83.3% ) in LASIK group have a residual dioptry between-1.00 Dand + 1. 00 D. The mean receding after 1 to 3-month surgery was 0.95 D in PRK group and 0. 76 D in LASIK group, and 0. 35 D and 0. 08 D respectively in two groups after 3 to 6-month surgery, and-0. 22 D and 0.00 Drespectively in two groups after 6 to 12-month surgery. There were significant differences in each phase between two techniques.CONCLUSION: It is safe to introduce PMMA disk united with bevelled mirror to correct hyperopia. Both PRK and LASIK can obtain satisfied long-term effectiveness, but LASIK with more stability and effectiveness as well as prediction.关键词
