RGPCL与框架眼镜对高度近视和散光的矫正效果

目的：探讨硬性透气性角膜接触镜（RGPCL）与框架眼镜对高度近视和散光的矫正效果。方法：回顾性自身对照研究。选择2017年1月至2018年12月在惠州爱尔眼科医院视光与小儿眼科门诊验配RGPCL且连续配戴1个月以上并在配戴RGPCL前连续配戴框架眼镜1个月以上的患者41例（75眼），其中高度近视眼38眼（高度近视组），高度散光眼37眼（高度散光组）。分别比较2组组内配戴框架眼镜和RGPCL的矫正效果。数据采用配对t检验进行比较。结果：41例（75眼）均成功验配RGPCL。高度近视组配戴RGPCL的最佳矫正视力（BCVA）为5.02±0.16，而配戴框架眼镜BCVA为4.91±0.16，差异有统计学意义（t=11.204，P=0.001），其中13眼BCVA在配戴RGPCL后提高2行至2行以上，1眼视力下降。高度散光组配戴RGPCL的BCVA为4.95±0.10，而配戴框架眼镜的BCVA为4.83±0.16，差异有统计学意义（t=8.431，P=0.001），其中12眼BCVA在RGPCL的配戴下提高2行至2行以上。结论：配戴RGPCL在矫正高度近视与散光的视力效果方面优于框架眼镜，具有临床优势。

The Effect of Refractive Correction with RGPCL Lenses and Frame Glasses in Patients with High Myopia and Astigmatism

Objective: To investigate the effect of rigid oxygen permeable contact lenses (RGPCLs) and frame glasses on high myopia and astigmatism. Methods: This was a retrospective self-controlled study. Patients were chosen to wear their habitual frame glasses for more than a month before wearing RGPCLs. Patients were recruited from January 2017 to December 2018 in the Optometry and Pediatric Ophthalmology Clinic of Huizhou Aier Eye Hospital. A total of 41 patients (75 eyes) participated in the study. Thirty-eight eyes had high myopia and 37 eyes had high astigmatism. The vision correction effects of wearing RGPCLs in the high myopia group and the high astigmatism group were compared to the original frame glasses. Data were analyzed by a paired t test. Results: Forty-one patients (75 eyes) successfully wore RGPCLs. The effect of wearing RGPCLs on the BCVA of the high myopia group was 5.02±0.16 and was 4.91±0.16 in the group that wore frame glasses; the difference was statistically significant (t=11.204, P=0.001). BCVA increased by 2 letters to more than 2 lines in 13 eyes when the wearing RGPCL, and visual acuity decreased in 1 eye. In addition, the BCVA of those wearing RGPCL in the high astigmatism group was 4.95±0.10, while the BCVA of those wearing glasses was 4.83±0.16. The difference was statistically significant (t=8.431, P=0.001). In addition, BCVA increased in 12 eyes by 2 lines or more with RGPCLs. Conclusions: The visual acuity effect of correcting high myopia and astigmatism after wearing RGPCLs is better than that for frame glasses, and has clinical advantages.
