Abstract

Uneventful myopic laser in situ keratomileusis (LASIK) was performed in both eyes of a 33-year-old woman. Two weeks after LASIK, examination of the left eye revealed flap striae radiating inferonasally from the superior hinge. The flap was relifted and repositioned to remove the irregular astigmatism and reduce the striae. Before the flap was relifted, Fourier-domain optical coherence tomography (FD-OCT) showed the gap at the temporal flap, which had not been detected by biomicroscopy. After the flap was relifted, FD-OCT documented that the gap was closed. High-resolution FD-OCT was helpful in the visualization and management of flap displacement.

摘要

一名33岁女性双眼均接受了顺利的准分子激光原位角膜磨镶术(LASIK)。LASIK术后两周,左眼检查发现瓣状条纹从上方铰链处向下鼻侧放射状分布。将瓣重新掀起并重新定位,以消除不规则散光并减少条纹。在瓣重新掀起之前,傅里叶域光学相干断层扫描(FD-OCT)显示颞侧瓣处有间隙,这是生物显微镜检查未检测到的。瓣重新掀起后,FD-OCT记录显示间隙已闭合。高分辨率FD-OCT有助于瓣移位的可视化和处理。
