Abstract: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.
