摘要
目的评价硬性透氧性隐形眼镜(RGP)矫正不规则散光的疗效。方法对23例(34眼)做眼科检查,包括视力,裂隙灯检查及验光,角膜地形图检查,确诊为不规则散光,排除隐形眼镜佩戴禁忌证,进行硬性透氧性角膜接触镜验配,对其最佳框架矫正视力及RGP矫正视力进行统计学比较。结果硬性透氧性角膜接触镜矫正不规则散光的最佳矫正视力(0.73±0.31),显著高于框架镜矫正值(0.48±0.30)(P<0.01),随访观察6个月视力稳定,无明显不良并发症。结论 RGP是矫正不规则散光有效安全方法,能够提高矫正视力及视觉质量。
Objective To evaluate the clinical efficacy of rigid gas permeable contact lens （RGPCL） in the correction of mixed astigmatism. Methods Twenty- three patients （36 eyes） with irregular astigmatism confirmed by corneal topography were selected as subjects. Routine eye checks including slit lamp check, refractive error check and corneal topography were performed to exclude contraindications of RGPCL. Best corrective visual acuities with spectacles and with rigid gas per- meable contact lens were analyzed. Results Corrective visual acuity of patients with RGPCL was （0.73± 0.31） and that with spectacles was （0.48 ± 0.30）. The difference was statistically signifi- cant （P〈 0.01）. No lasting complications were observed during the six- month follow- up. Con- clusion RGPCL is an effective tool to correct irregular astigmatism and can improve corrected visu- al acuity.
