【摘要】：目的评估Toric硬性透气性角膜接触镜(rigid gas-permeable contact lens,RGPCL)对高度散光眼的视力矫正作用。方法收集高度散光患者33例(62眼),单纯角膜散光或眼内散光1.00 DC验配后环曲面RGPCL,眼内散光≥1.00 DC验配双环曲面RGPCL。对高度散光眼配戴框架镜及Toric RGPCL的视力矫正效果进行比较;对2.00~4.00 DC、4.00 DC散光眼配戴Toric RGPCL相对框架镜的矫正幅度进行比较;对伴有高度近远视、低中度近远视的散光眼配戴Toric RGPCL的视力矫正效果进行比较。结果 53眼验配后环曲面RGPCL,相对裸眼视力提高0.67±0.24,9眼验配双环曲面RGPCL,相对裸眼视力提高0.50±0.24,两种Toric RGPCL对视力的矫正作用均明显优于框架镜(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后相对框架镜矫正视力分别提高0.17±0.15、0.26±0.14,两者比较差异有统计学意义(t=2.47,P=0.016);伴有不同球镜度数的高度散光眼配戴Toric RGPCL后,视力矫正效果差异无统计学意义(t=0.47,P0.05)。结论 Toric RGPCL对高度散光眼有理想的矫正效果,且对于4.00 DC散光眼矫正效果更佳,其对散光的矫正作用与球镜度无关。
[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，
