1、固體激光治療高度近視的療效分析作者：宋玉英楊冠尹茶仙單位：上海市第六人民醫(yī)院眼科(200233)關(guān)鍵詞：固體激光：高度近視：光學(xué)角膜切削術(shù)摘要目的：評價(jià)固體激光光學(xué)角膜切削術(shù)治療高度近視的療效。方法：應(yīng)用LightBlade?IIp.
2、體激光手術(shù)系統(tǒng)進(jìn)行光學(xué)角膜切削術(shù)治療高度近視-6?12?-16.00D106例180眼，隨訪12?24月，回顧性評價(jià)療效和并發(fā)癥。結(jié)果：180眼術(shù)前平均球鏡屈光度-8.19±0.53D,術(shù)后1年-0.47±0.42D。術(shù)前平均角膜屈光力43.24±0.26D,術(shù)后39.89±0.50Do在12個月時(shí)，試矯和實(shí)矯屈光
3、度相差0.50D內(nèi)58.95%,1.00D內(nèi)93.33%,2.00D內(nèi)98.33%。術(shù)后1年裸視力1.0占57.22%,裸視力0?5占95%,最好矯正視力達(dá)到術(shù)前水平80%,超過1行6.67%,超過2行3.33%,下降1行8.89%,t降2行1.11%。術(shù)后角膜I級haze1,3,6,12月分別是52.22%,42.78%,45%,45.56%,II級haze分別是19.44%、15%、12.78%、8.33%,III級haze1眼0.56%o10眼屈光回退6?17月再手術(shù)。4眼激素性眼壓升高，用藥后恢復(fù)。結(jié)論：固體激光治療高度近視安全有效，沒有
