We have combined an anterior segment (AS) optical coherence tomography (OCT) system and a wavefront-based aberrometer with an approach that senses ocular wavefront aberrations using the OCT beam. Temporal interlacing of the OCT and aberrometer channels allows for OCT images and refractive error measurements to be acquired continuously and in real-time. The system measures refractive error with accuracy and precision comparable to that of clinical autorefractors. The proposed approach provides a compact modular design that is suitable for integrating OCT and wavefront-based autorefraction within the optical head of the ophthalmic surgical microscope for guiding cataract surgery or table-top devices for simultaneous autorefraction and ocular biometry.
我们将前段（AS）光学相干断层扫描（OCT）系统和基于波前的像差仪相结合，采用一种利用OCT光束感测眼波前像差的方法。OCT通道和像差仪通道的时间交织允许连续实时获取OCT图像和屈光不正测量值。该系统测量屈光不正的准确性和精度与临床自动验光仪相当。所提出的方法提供了一种紧凑的模块化设计，适用于将OCT和基于波前的自动验光功能集成到眼科手术显微镜的光学头内，以指导白内障手术，或集成到台式设备中以同时进行自动验光和眼部生物测量。
