目的：评估硬性透气性接触镜(rigid gas permeable contact lens，RGPCL)对高度近视合并角膜散光的矫治效果。
方法：对高度近视合并角膜散光患者72例118眼验配RGPCL，1mo后复诊记录戴镜矫正视力。综合验光记录的最正之最佳矫正视力为对照。将RGPCL的最佳矫正视力与最正之最佳矫正视力比较。
结果：综合验光最正之最佳矫正视力情况，其中4.7共17眼(14.4%)，4.8共52眼(44.1%)，4.9～5.0共49眼(41.5%)。RGPCL最佳矫正视力情况，其中4.7共6眼(5.1%)，4.8共21眼(17.8%)，4.9～5.0共91眼(77.1%)。RGPCL矫正视力4.9～5.0提高了42眼(35.6%)，差异有统计学意义。
结论：RGPCL对高度近视合并角膜散光患者的矫治效果好。

AIM: To evaluate the effect of rigid gas permeable contact lens(RGPCL)for high myopia with corneal astigmatism.
METHODS: Totally 72 patients(118 eyes)with high myopia with corneal astigmatism were fitted with RGPCL, and the corrected visual acuity were recorded after one month. The MPMVA(maximum plus to maximum visual acuity)were recorded by comprehensive refraction. The corrected visual acuity of RGPCL was compared with the MPMVA.
RESULTS: There were 17 eyes of 4.7(14.4%), 52 eyes of 4.8(44.1%)and 49 eyes of 4.9-5.0(41.5%)in comprehensive refraction. There were 6 eyes of 4.7(5.1%), 21 eyes of 4.8(17.8%)and 91 eyes of 4.9-5.0(77.1%)in RGPCL corrected visual acuity. RGPCL corrected visual acuity of(4.9-5.0)improved in 42 eyes(35.6%), and the difference was statistically significant.
CONCLUSION: The application of RGPCL can correct high myopia with corneal astigmatism, and has an excellent clinical result.
