准分子激光原位角膜磨镶术治疗-10D以上高度近视的疗效观察

Observation of Effect of Lasik in Correcting Myopia more than-10.00D

目的评价LASIK手术对-10．00D以上高度近视眼的疗效及安全性。方法67只-1000D以上高度近视眼接受LASIK手术，术前平均等值球镜度-15．18±485D（－10.00-－2900D），术后随访6个月。结果术后6个月，探眼视力≥0．5占83．58％（56／67），低于0．5占16．42％（11／67），达到或超过术前最好矫正视力的眼占48．39％（33／67），屈光度在±1．00D以内，占35．82％（24／67），其余均大于±1．00D，主要为欠矫，未发生严重损害视力的并发症。结论虽然LASIK术对-10．00D以上近视眼治疗的预测性不尽人意，但大多数限术后获得较满意的裸眼视力，并且手术比较安全，是一种可选择的高度近视治疗方法。

To evaluate the safety and effectiveness of Lasik in correcting myopia more than - 10. 00D. Method Lasik was applied to 67 eyes which the mean spherical equivalent refraction were - 15 - 18 ± 4.85D. (range10 .00to- 29.00D). Follow - up was 6 months. Resuls 6 months after Lasik, 56 eyes (83. 58 % ) had an uncorrected vishal acuity of 0. 5 or better. 33 eyes(49. 25 % )reached or over their best preoperation uncorrected visual acuity. The residual refraction of 24 eyes (35 .82% ) was within ± 1. 00D. No sight - threatening complication occurred. Conclusion Lasik is an efficient and relatively safe procedure for myOpia more than - 10. 00D, though its predictability is unsatisfied.
