1、固体激光治疗高度近视的疗效分析作者：宋玉英杨冠尹茶仙单位：上海市第六人民医院眼科(200233)关键词：固体激光：高度近视：光学角膜切削术摘要目的：评价固体激光光学角膜切削术治疗高度近视的疗效。方法：应用LightBlade™IIp.
2、体激光手术系统进行光学角膜切削术治疗高度近视-6・12〜-16.00D106例180眼，随访12〜24月，回顾性评价疗效和并发症。结果：180眼术前平均球镜屈光度-8.19±0.53D,术后1年-0.47±0.42D。术前平均角膜屈光力43.24±0.26D,术后39.89±0.50Do在12个月时，试矫和实矫屈光
3、度相差0.50D内58.95%,1.00D内93.33%,2.00D内98.33%。术后1年裸视力1.0占57.22%,裸视力0・5占95%,最好矫正视力达到术前水平80%,超过1行6.67%,超过2行3.33%,下降1行8.89%,t降2行1.11%。术后角膜I级haze1,3,6,12月分别是52.22%,42.78%,45%,45.56%,II级haze分别是19.44%、15%、12.78%、8.33%,III级haze1眼0.56%o10眼屈光回退6〜17月再手术。4眼激素性眼压升高，用药后恢复。结论：固体激光治疗高度近视安全有效，没有
