眼科手术需要精细的影像辅助，而传统双目手术显微镜的成像视场局限在X-Y平面，无法提供Z方向的手术病灶区域图像信息。因此，为了进一步提高手术成功率、减小手术创伤、降低手术后并发症，申请人提出开展“基于SS-OCT的手术导航显微镜技术研究”。该新型的手术显微镜结合了1000nm波段超长成像深度（20mm）扫频光源光学相干层析成像装置（SS-OCT），能同时满足眼前段和眼后段的成像波长需求，获取从角膜和视网膜的高速全眼3D断层图像，从而实现从眼前段到眼后段的多种眼科手术引导。利用头戴式虚拟显示技术，将SS-OCT的3D图像与人眼自身视觉图像进行融合显示，并设计利用声控/触控技术，实现引导图像的各种显示操作。通过离体/活体动物眼球的手术应用实验，研究不同手术与所需图像导航信息之间的关联性，探索3D图像导航的眼科微创手术方法，丰富我国眼科显微外科手术技术，填补该领域的空白。

Ophthalmic surgery requires sophisticated image as auxiliary. However, due to the field of view is limited to X-Y plane, conventional binocular surgical microscope cannot provide information of lesion area through Z direction. Therefore, in order to improve the success rate, reduce surgical trauma, and decrease post-operative complications, the applicant proposed to carry out the research of “SS-OCT Navigating Surgical Microscopy”. The surgical microscope incorporates a 1000nm swept-source OCT with ultra-long image depth (20mm), which meets the imaging.wavelength need of both anterior segment and posterior segment. A high-speed 3D tomography from anterior segment to retina can be obtained, which boots a full-eye surgical navigation. A head-mounted virtual display technology is also implemented to the surgical microscope. The 3D OCT image is directly fused with the operator’s own visual image. Besides, the use of voice and touch technology can achieve a variety of boot image display operation. This study will combine in vitro and in vivo animal’s eye surgical experiments to access the relevance between different surgeries and the desired surgical navigation information. The research will form the methodology of minimally invasive ophthalmic surgery, improve ophthalmic microsurgery techniques, and fill in the blank of this field.
