目的 观察RoseK硬性透气性角膜接触镜 (RoseKRGP)矫治圆锥角膜的临床应用效果。方法 在角膜地形图指导下 ,为 12 6人 2 18眼圆锥角膜验配RoseKRGP ,评估镜片配适状态 ,比较最佳框架眼镜和RoseKRGP矫正视力 ,随访 6～ 2 7个月 ,观察并发症的发生情况。结果 所有病例均能通过RoseKRGP获得满意的矫正视力 ,RoseKRGP与框架眼镜矫正视力比较差别有显著意义 (t=10 90 ,P <0 0 0 0 1)。 16 9眼 (77 5 2 % )为三点接触配适状态 ,38眼 (17 4 3% )为顶点离开的配适状态 ,11眼 (5 0 5 % )为可接受的顶点接触配适状态。结论 在角膜地形图指导下 ,圆锥角膜患者验配RoseKRGP成功率高 ,容易达到比较好的配适状态 ,获得满意的矫正视力 ,且无严重并发症发生 ,值得在临床上推广应用。
Objective To observe the clinical effect of RoseK rigid grafts (RoseKRGP) in the treatment of keratoconus. Methods Under the guidance of corneal topography, 12 6 eyes with 18 keratoconus keratoses were assigned to RoseKRGP to assess the state of lens fitting. The best glasses and RoseKRGP were used to correct eyesight. The patients were followed up for 6 to 27 months to observe the complications Happening. Results All cases were able to obtain satisfactory corrected visual acuity through RoseKRGP. There was significant difference between RoseKRGP and frame glasses corrected visual acuity (t = 10 90, P 0 01 0 1). Sixteen eyes (77 5 2%) were fit for the three-point contact, 38 (17.43%) were for the one-sided fit, and 11 (55%) were for the one-touch fitting . Conclusion Under the guidance of corneal topography, the success rate of RoseKRGP in patients with keratoconus is easy to reach a good state of fit, to obtain satisfactory corrected visual acuity, and no serious complications, worthy of clinical application.
