我们描述了硬性透气性（RGP）接触镜辅助的白内障手术在严重圆锥角膜患者。严重圆锥角膜患者行白内障手术时，由于角膜散光的不规则性，导致眼内图像失真，视觉透视丧失。视力差可导致并发症，包括后囊膜破裂和角膜内皮细胞损伤。为了克服这些问题，在2例患者中将RGP接触透镜放置在角膜上。图像失真明显减少，视觉透视得到改善。安全地进行了眼内操作，如冲洗/抽吸。透照的改善导致前囊和后囊膜的良好可视化。两例患者均未发生术中或术后并发症。该技术在严重圆锥角膜患者的白内障手术中提供了极好的可视化。
We describe rigid gas-permeable (RGP) contact lens–assisted cataract surgery in patients with severe keratoconus. During cataract surgery in cases with severe keratoconus, the intraocular images are distorted and visual perspective is lost because of irregular corneal astigmatism. Poor visibility can lead to complications, including posterior capsule rupture and corneal endothelial cell damage. To overcome these problems, an RGP contact lens was placed on the cornea in 2 cases. The image distortion decreased markedly, and the visual perspective improved. Intraocular manipulations such as irrigation/aspiration were performed safely. Improvement in transillumination led to good visualization of the anterior and posterior capsules. No intraoperative or postoperative complications developed in either case. This technique provided excellent visualization during cataract surgery in patients with severe keratoconus.
