摘要
目的评价准分子激光原位角膜磨镶术矫正高度近视术后5年的效果和安全性。方法对接受准分子激光原位角膜磨镶术矫正近视术后5年的高度近视患者80例（136只眼）进行裸眼远视力、屈光度及矫正远视力的随访，被随访眼按屈光度数分为2组：A组：-6．00D-8．00D（93只眼），B组：〉-8．00D（43只眼）。结果术后5年裸眼远视力≥0．5、≥1．0分别为96％、68％，术后矫正远视力不变及上升1行比率为50％。术后A组、B组裸眼远视力1〉0．5所占比率分别为98．9％、88．4％，差异有统计学意义（P〈0．05），≥1．0所占比率分别为73．1％、55．8％，差异有统计学意义（P〈0．05）。术后5年屈光度平均（-0131±O．57）D，稳定在±O．50D、±1．00D及±2．00D以下的比率分别是70．59％（96只眼）、83．09％（113只眼）、97．79％（133只眼），A组、B组屈光回退≥1．0D比率分别为11．8％、21．9％，差异有统计学意义（P〈0．05）。术后5年散光平均（-0．07±0．22）13。术后并发症少。结论准分子激光原位角膜磨镶术矫正高度近视是安全有效地手术方式之一，术后远期视力及屈光度稳定，手术安全性好。
Objective To evaluate the effect and safety of laser in situ keratomileusis （LASIK） in treating high myopia at 5 years after surgery. Methods LASIK was performed on 136 eyes of 80 patients who were followed up for five years. The patients were divided into two groups accord- ing to their degree of preoperative myopia according to diopter （group A： -6.00D--8.00D, 93 eyes; group B： 〉-8.00D, 43 eyes）. Results Among 80 patients with high myopia, uncorrected distance visual acuity （UDVA） at five years was 0.5 or better in 96%, 1.0 or better in 68%. Compared with preoperative corrected distance visual acuity （CDVA）, the percentage of CDVA remaining and gained one line was 50%. The percentage of UDVA ≥0.5 in group A and B was 98.9%, 88.4%, respectively, there was significant different between them （P 〈0.05）. The percentage of UDVA ≥1.0 in group A and B was 73.1%, 55.8%, respectively, there was significant different between them （P 〈0.05）. The mean spherical equivalent was （-0.31±0.57）D with 70.59% ±0.50D, 83.09% ±1.00D and 97.79% ±2.00D of intended refraction. The percentage of regressive degree ≥1.0D in group A and B was 11.8%, 21.9%, respectively, there was significant different between them （P 〈0.05）. The mean refractive astigmatism was （-0.07±0.22）D. The complications were few. Conclusions LASIK for high myopia is an effective and safe procedure with vision acuity and refractive power stable in the long-term.
