An optical switch was implemented in the reference arm of an extended depth SD-OCT system to sequentially acquire OCT images at different depths into the eye ranging from the cornea to the retina. A custom-made accommodation module was coupled with the delivery of the OCT system to provide controlled step stimuli of accommodation and disaccommodation that preserve ocular alignment. The changes in the lens shape were imaged and ocular distances were dynamically measured during accommodation and disaccommodation. The system is capable of dynamic in vivo imaging of the entire anterior segment and eye-length measurement during accommodation in real-time.
在扩展深度的频域光学相干断层扫描(SD - OCT)系统的参考臂中安装了一个光开关,以便在从角膜到视网膜的不同眼内深度依次采集OCT图像。一个定制的调节模块与OCT系统相连,以提供可控的调节和放松的步进刺激,同时保持眼部对准。在调节和放松过程中,对晶状体形状的变化进行成像,并动态测量眼轴长度。该系统能够在调节过程中对整个眼前节进行动态活体成像,并实时测量眼轴长度。
