目的观察硬性透气性角膜接触镜(RGP隐形眼镜)对角膜外伤手术后不规则散光的矫治作用及视觉质量。方法对28例(28眼)近视<-8.50D,散光-6.50D~+4.00D者配戴RGP隐形眼镜,观察配适情况和矫正效果。结果配戴RGP隐形眼镜最佳矫正视力0.4~1.2,≥0.8者15眼(53.57%)。结论角膜外伤后造成不规则性散光者配戴RGP隐行眼镜后能达到最佳矫正视力和更好视觉质量。
Objective To observe the correction and visual quality of irregular astigmatism after corneal trauma with rigid gas permeable contact lens (RGP contact lens). Methods 28 cases (28 eyes) of myopia <-8.50D, astigmatism -6.50D ~ + 4.00D were wearing RGP contact lenses to observe the fit and the correction effect. Results The best corrected visual acuity of wearing RGP contact lenses was 0.4 ~ 1.2, and 15 eyes (53.57%) ≥0.8. Conclusion Irregular astigmatism caused by corneal trauma can achieve the best corrected visual acuity and better visual quality after wearing RGP stealth glasses.
