To examine the use of optical coherence tomography (OCT) in evaluating anatomical changes after laser in situ keratomileusis (LASIK) and complications related to the interface and corneal flap.
Istanbul University Eye Research Center and Department of Ophthalmology, Cerrahpasa Medical School, Istanbul, Turkey.
Eleven eyes of 11 patients who had myopic LASIK were included in the study. Mean age of the 7 men and 4 women was 29.4 years +/- 6.9 (SD). Cases analyzed included uneventful LASIK (4 eyes), epithelial ingrowth (5 eyes), and flap striae (2 eyes). Corneas were examined by OCT (Humphrey Systems).
Optical coherence tomography resolved corneal flap and residual stromal layers in all cases. The mean thickness of the corneal flap and residual stroma was 138.2 +/- 16.5 microm and 321.7 +/- 32.1 microm, respectively. Interface between the corneal flap and residual stroma was shown by OCT. Optical coherence tomography revealed that the eye with flap striae had flap displacement undetected by biomicroscopy. Epithelial ingrowth was shown as a highly reflective area.
Optical coherence tomography appears to be a promising method for evaluating anatomical changes in the cornea after LASIK.
研究光学相干断层扫描（OCT）在评估准分子原位角膜磨镶术（LASIK）后解剖结构变化以及与界面和角膜瓣相关并发症方面的应用。
土耳其伊斯坦布尔伊斯坦布尔大学眼科研究中心及切拉皮帕萨医学院眼科。
本研究纳入了11例行近视LASIK手术患者的11只眼。7名男性和4名女性的平均年龄为29.4岁±6.9（标准差）。分析的病例包括无并发症的LASIK（4只眼）、上皮内生（5只眼）和瓣条纹（2只眼）。使用OCT（汉弗莱系统）检查角膜。
在所有病例中，光学相干断层扫描均能分辨角膜瓣和剩余基质层。角膜瓣和剩余基质的平均厚度分别为138.2±16.5微米和321.7±32.1微米。OCT显示了角膜瓣与剩余基质之间的界面。光学相干断层扫描显示，有瓣条纹的眼睛存在生物显微镜未检测到的瓣移位。上皮内生表现为高反射区。
光学相干断层扫描似乎是评估LASIK术后角膜解剖结构变化的一种有前景的方法。
