目的: 评价硬性透气性隐形眼镜( RGP) 矫正圆锥角膜屈光异常的疗效。方法: 选择我院 2004- 05/2005- 12 收治的 25 例( 43 眼) 圆锥角膜患者配戴 RGP, 观察视力、角膜曲率、配适状况、舒适度及并发症。结果: RGP矫正视力均好于或等于框架球柱面联合镜。其中优于框架球柱面联合镜片者 37 眼( 86.0%) , 二者视力相等者 6 眼( 14.0 %) , 矫正视力低于框架球柱面联合镜者 0眼, 经统计学处理, 两者有显著性差异( P< 0.01) 。配戴RGP 6mo 时角膜曲率值没有明显变化。本组病例配适良好, 合并症少而轻。结论: 经 6mo 随访观察, RGP 对圆锥角膜的视力矫正明显优于框架眼镜, 是目前矫正圆锥角膜的非手术治疗的有效方法。
Objective: To evaluate the curative effect of rigid gas permeable contact lens (RGP) for correction of keratoconus refractive errors. Methods: Forty-five patients (43 eyes) with keratoconus admitted to our hospital from 2004 to 2005/2005 were enrolled in the study. The visual acuity, corneal curvature, fit status, comfort and complications were observed. Results: RGP corrected visual acuity were better than or equal to the framework of the spherical cylindrical mirror. Among them, 37 eyes (86.0%) were better than those with spherical lens, 6 eyes (14.0%) had equal vision, and corrected visual acuity was lower than 0 There was significant difference (P <0.01). There was no significant change in corneal curvature value when wearing RGP for 6 months. This group of patients well-fitted, less complicated and light. Conclusion: After 6mo follow-up observation, RGP visual acuity of keratoconus is obviously better than that of frame glasses, which is an effective method for non-surgical treatment of keratoconus.
