LASIK治疗远视的临床研究及疗效评价

Clinical study of laser in situ keratomileusis for treatment of hypermetropia

目的 探讨准分子激光角膜原位磨镶术治疗远视的疗效、治疗时机及存在问题。方法 采用美国 Novatec公司生产 2 0 7nm的固态准分子激光对 390只远视眼进行了L ASIK,并分别于 1、3、6、12 m o进行复查和随访。结果 L ASIK激光手术治疗 + 2 .0 0～ +10 .0 0 D远视及散光 ,术后均有明显疗效 ,且较继往几种术式稳定可靠 ,回退率低且幅度小。术后 6～ 12 mo疗效即已稳定。 87%屈光度稳定在 + 2 .0 0 D以内 ,6 2 %屈光度稳定在 +1.0 0 D以内。 L ASIK较其他术式恢复快 (平均 2 d)、反应轻 ,远视屈光度消减明显 ,视力提高显著 ,弱视患儿术后训练较未施术者视力提高快而显著。结论 L

Objective To evaluate therapeutic effect and opportunity of laser in situ keratomileusis(LASIK) for treatment of hypermetropia.Methods Three hundred and ninety hypermetropia eyes were treated with LASIK using solid excimer laser instrument(made in Novatec Corporation, USA),and were reexamined at 1,3,6 and 12 months after LASIK.Results Therapeutic effect of LASIK was more remarkable, stable and reliable, that of other methods in treating +2.00^+10.00D hypermetropia and astigmatism, and the rate and degree of refraction regression were small. The diopter has been stable in 6~12 months after LASIK. Diopter of 87 percentage of all eyes≤+2.00D, and 61 percentage≤+1.00D. LASIK had shorter recovery time, more gently operation reaction, more remarkable droping of diopter than other methods. Elevation of vision was remarkable after LASIK. Elevation of vision of amblyopia children who were treated with LASIK was quicker and more remarkable after treatment of amblyopia than that of other amblyopia children who were not treated with LASIK.Conclusion At present, LASIK is the best therapeutic method to treat hypermetropia.
