Abstract

A 39-year-old woman developed corneal ectasia after laser in situ keratomileusis. Intracorneal ring segments (Intacs, Addition Technology, Inc.) were placed in the left eye in November 2004. Postoperatively, inferior topographic steepening decreased significantly and a rigid gas-permeable lens yielded 20/25 visual acuity. However, the patient reported persistent discomfort that did not improve with topical medications or a bandage contact lens. In May 2005, confocal microscopy demonstrated a corneal nerve in direct contact with the inferior segment. Both segments were removed, and after removal, the patient reported complete resolution of the pain.

摘要

一名39岁女性在准分子原位角膜磨镶术后出现角膜扩张。2004年11月，在其左眼植入了角膜内环片（Intacs，Addition Technology公司）。术后，下方地形变陡明显减轻，佩戴硬性透气性角膜接触镜后视力达到20/25。然而，患者报告持续不适，局部用药或佩戴绷带式隐形眼镜均无法改善。2005年5月，共焦显微镜检查显示一条角膜神经与下方环片直接接触。随后取出了两片环片，取出后患者报告疼痛完全缓解。
