【摘要】：目的評估Toric硬性透氣性角膜接觸鏡(rigid gas-permeable contact lens,RGPCL)對高度散光眼的視力矯正作用。方法收集高度散光患者33例(62眼),單純角膜散光或眼內(nèi)散光1.00 DC驗配后環(huán)曲面RGPCL,眼內(nèi)散光≥1.00 DC驗配雙環(huán)曲面RGPCL。對高度散光眼配戴框架鏡及Toric RGPCL的視力矯正效果進行比較;對2.00~4.00 DC、4.00 DC散光眼配戴Toric RGPCL相對框架鏡的矯正幅度進行比較;對伴有高度近遠視、低中度近遠視的散光眼配戴Toric RGPCL的視力矯正效果進行比較。結(jié)果 53眼驗配后環(huán)曲面RGPCL,相對裸眼視力提高0.67±0.24,9眼驗配雙環(huán)曲面RGPCL,相對裸眼視力提高0.50±0.24,兩種Toric RGPCL對視力的矯正作用均明顯優(yōu)于框架鏡(t=9.21,P=0.00;t=6.49,P=0.00);2.00~4.00 DC、4.00 DC散光眼配戴Toric RGPCL后相對框架鏡矯正視力分別提高0.17±0.15、0.26±0.14,兩者比較差異有統(tǒng)計學(xué)意義(t=2.47,P=0.016);伴有不同球鏡度數(shù)的高度散光眼配戴Toric RGPCL后,視力矯正效果差異無統(tǒng)計學(xué)意義(t=0.47,P0.05)。結(jié)論 Toric RGPCL對高度散光眼有理想的矯正效果,且對于4.00 DC散光眼矯正效果更佳,其對散光的矯正作用與球鏡度無關(guān)。
[Abstract]:Objective to evaluate the effect of Toric rigid breathable contact lens (rigid gas-permeable contact lens,RGPCL) on visual acuity of high astigmatism. Methods 33 patients (62 eyes) with high astigmatism were collected. Corneal astigmatism or intraocular astigmatism was measured by 1. 00 DC or 1. 00 DC with posterior annular surface RGPCL, 鈮，
