We report a case of Ferrara intracorneal ring (Mediphacos) implantation and cataract surgery for the correction of pellucid marginal corneal degeneration. Preoperatively, the patient's uncorrected visual acuity (UCVA) was 0.05 in the right eye and 0.10 in the left eye. The best spectacle-corrected visual acuity (BSCVA) was 0.50 with -2.00 -11.25 x 80 in the right eye and 0.60 with -2.00 -5.50 x 95 in the left eye. One month postoperatively, the UCVA was 0.50 in the right eye and 0.30 in the left eye. The BSCVA was 0.80 with -1.00 in the right eye and 0.60 with -0.75 -1.25 x 160 in the left eye. Ferrara intrastromal rings and cataract surgery resulted in a more regular corneal shape with a reduction in astigmatism for good visual recovery.
我们报告了一例使用费拉拉角膜内环（Mediphacos）植入术和白内障手术来矫正透明边缘角膜变性的病例。术前，患者右眼的未矫正视力（UCVA）为0.05，左眼为0.10。最佳矫正视力（BSCVA）右眼为0.50，散光度数为-2.00 -11.25×80，左眼为0.60，散光度数为-2.00 -5.50×95。术后1个月，右眼UCVA为0.50，左眼为0.30。右眼BSCVA为0.80，散光度数为-1.00，左眼为0.60，散光度数为-0.75 -1.25×160。费拉拉基质内环和白内障手术使角膜形状更规则，散光减少，视力恢复良好。
