硬性透气性接触镜矫治高度近视合并角膜散光

Clinical evaluation of rigid gas permeable contact lens for high myopia with corneal astigmatism

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＆amp;nbsp;high myopia with corneal astigmatism, and has an excellent clinical result.
