摘要
目的分析准分子激光近视矫正术的远期疗效。方法选择2002年10月至2004年3月于荆州市中心医院行准分子激光近视矫正术治疗,且随诊10年、资料完整的近视患者136例(241眼)。将241眼分为中度近视组(近视度-3.00^-6.00D,48眼)、高度近视组(近视度-6.00^-10.00D,134眼)和超高度近视组(近视度-10.00^-16.00D,59眼)。术后随诊10年,观察并记录视力、屈光度、角膜前表面曲率和眼压。结果中度近视组术后10年裸眼视力大于0.5和1.0比例分别为100.00%、84.00%,高度近视组分别为100.00%、83.95%,超高度近视组分别为91.45%、33.33%。各研究组术后10年最佳矫正视力达到或超过术前最佳矫正视力的比例分别是98.21%、98.43%、92.34%。术后第1年屈光度回退明显,超高度近视组回退量最大,中度近视组回退量最小;术后第2~10年,超高度近视组屈光度回退最大,中度和高度近视组回退不明显。术后第1年角膜前表面曲率变化较之后更明显,超高度近视组角膜前表面曲率改变最多,中度近视组改变最少。术后10年随诊时,患者眼压均在正常范围内。结论准分子激光近视矫正术远期效果稳定,是治疗近视有效且安全的方法,但近视程度越大,手术效果的预测性及术后视力稳定性越小。
Objective To analyze the long-term efficacy of excimer laser refractive surgery（ELRS） .Methods A total of 136 pa-tients（241 eyes） ,receiving ELRS therapy from Oct .2002 to Mar .2004 ,were followed up for 10 years ,and divided into moderate myopia group（ - 3 .00 - 6 .00 D ,48 eyes） ,high myopia group（ - 6 .00 - 10 .00 D ,134 eyes） and ultra-high myopia group（ - 10 .00 -16 .00 D ,59 eyes） .Patients were followed up for 10 years to observe vision ,diopter ,anterior corneal surface curvature（ACSC） and intra-ocular tension .Results Ten years after treatment ,the proportion of uncorrected vision greater than 0 .5 and 1 .0 were 100 .00% and 84 .00% in moderate myopia group ,100 .00% and 83 .95% in high myopia group ,91 .45% and 33 .33% in ultra-high myopia group .Ten years after treatment ,the proportion of best corrected vision ,reaching or exceeding the preoperative best correc-ted vision were 98 .21% ,98 .43% and 92 .34% in the three groups .The amount of refraction of diopter in the first year was obvi-ous ,which of high myopia group was the largest ,and of moderate myopia group was the lowest .In the 2 - 10 years after treatment , the fallback of diopter in ultra-high myopia was the most obvious ,and those of the moderate and high myopia group were not obvi-ous .The change of ACSC in the first year after treatment was more abvious than that from the second year after treatment ,and the change of ACSC in ultra-high myopia group was the largest ,and that of moderate group was the lowest .During the 10 years of fol-low-up ,the intra-ocular pressure were within normal range .Conclusion ELRS could be with stable long-term efficacy for the treat-ment of myopia ,but with the increasing of the degree of myopia ,the predicted stability of the effect and post-operative stability of vision could be decreased .
