目的:使用前节OCT分析高度近视植入虹膜夹型人工晶状体后眼内的结构变化。方法:植入前房晶状体矫正高度近视6眼(11.5D至22.0D),使用前节OCT采集前节图像测量术前前房深度,术后人工晶状体与角膜内皮间距离(内皮—晶状体距离),人工晶状体与正常晶状体间距离。结果:术前前房深度为3.27～3.91mm,术后内皮—晶状体距离为2.07～2.24mm。人工晶状体后表面与正常晶状体间的距离为0.82～1.32mm。图像显示虹膜色素层没有明显改变。结论:前房深度较术前减少36.1%～44.6%。前节OCT对于检测虹膜夹型前房晶状体的位置有帮助。
OBJECTIVE: To analyze the intraocular structural changes after anterior segment intraocular lens implantation in patients with iris-clamp intraocular lens implantation. Methods: Anterior chamber lenses were implanted in 6 eyes (11.5D to 22.0D). The anterior segment depth of anterior chamber, distance between intraocular lens and corneal endothelium (endothelium - lens distance) , Intraocular lens and normal lens distance. Results: The depth of anterior chamber was 3.27-3.91mm and the distance between endothelium and lens was 2.07-2.24mm. The distance between the posterior surface of the intraocular lens and the normal lens is 0.82 ~ 1.32mm. The image shows no significant change in the iris pigment layer. Conclusion: The depth of anterior chamber decreased 36.1% ~ 44.6% compared with that before operation. The anterior OCT helps detect the position of the iris-clip anterior chamber lens.
