硬性透氧性角膜接触镜矫正特殊类型屈光不正的效果观察

The rigid gas permeable contact lens for the correction of special ametropia

目的 观察硬性透氧性角膜接触镜（rigidgas permeable contactlens,RGPCL）矫正特殊类型屈光不正的临床疗效及安全性.方法 收集验配RGPCL的患者61例（98只眼）,包括高度近视29例（55只眼）、高度散光9例（18只眼）、无晶状体高度远视20例（20只眼）、屈光参差3例（5只眼）.在裂隙灯下进行荧光素染色配戴评估后确定处方,定期复查随访6～12个月.结果 98眼均一次配适成功.高度近视组佩戴框架眼镜和RGPCL后矫正视力≥4.9分别为37眼（67.27%）、47只眼（85.46%）,平均最佳矫正视力RGPCL好于框架眼镜（P〈0.05）;无晶状体眼高度远视组佩戴框架眼镜和RGPCL后矫正视力≥4.9分别为7眼（38.9%）、6只眼（33.3%）,平均最佳矫正视力两者间无差异（P〉0.05）;高度散光组佩戴框架眼镜和RGPCL后矫正视力≥4.9分别为15只眼（75%）、20只眼（100%）,平均最佳矫正视力RGPCL好于框架眼镜（P〈0.05）;屈光参差者佩戴RGP后达到双眼平衡.随访未发现明显眼部并发症.结论 对于特殊类型屈光不正,RGPCL的视觉效果明显优于框架眼镜,并有较高地安全性,无明显并发症发生.

Objective To evaluate the effectiveness and safety of rigid gas permeable contact lenses （RGPCL） for special ametropia. Methods Of 61 patients （98 eyes）, including high myopia 29 （55 eyes）, high degree of astigmatism 9 （18 eyes）, 20 non-lens high hyperopia （20 eyes）, anisometropia 3 （5 eyes）, were fitted with RGPCLs. They were followed up for 6 to 12 months. Results High myopia to wear spectacles and RGPCLs, Best corrected visual acuity （BCVA） ≥ 4.9 were 37 eyes （67.27%） and 47 （85.46%） respectively, the average BCVA RGPCLs better than spectacles （P 〈0.05）. Non-lens high hyperopia group after wearing spectacles and RGPCLs BCVA ≥ 4.9 were 7 eyes （38.9%） and 6 eyes （33.3%） respectively. There was no difference between them （P〉0.05）. In the high astigmatism group, BCVA was better than 4.9 in 20 eyes （100%） with RGPCLs and in 15 eyes （75%） with spectacles. The average BCVA, RGPCLs were better than spectacles （P 〈0.05）.Anisometropia patients obtained binocular balance with RGPCLs. No serious complications occurred within follow-up period. Conclusions RGPCL is safe and more effective than with spectacles for special ametropia significantly.
