Abstract：
OBJECTIVE: To describe the advantages of Ngenuity 3D digital filters for enhancing visualization during cataract and corneal transplant surgery.
METHODS: All surgeries were performed by the same experienced surgeon (L.M.) using the Ngenuity 3D heads-up visualization system connected to a microscope. Images were simultaneously captured with and without the filter in each of the following phases: endothelial evaluation, capsulorhexis, capsule rupture, vitreous leak, cortex removal, visco removal, corneal suture, descemetorhexis, DMEK graft preparation and insertion.
RESULTS: In cataract surgery, green and monochrome filters facilitate capsulorhexis in difficult situations by highlighting the anterior capsule and can improve visualization of a posterior capsular tear. The enhanced contrast of the monochrome filter is also useful for cortex and viscoelastic removal. In corneal surgery, the green filter highlights the rim of the DMEK graft during tissue preparation, the yellow filter enhances the contrast of the stained DMEK graft in the anterior chamber, the monochrome filter simplifies descemetorhexis by improving visualization of the Descemet/endothelial layer and allows a better view in red saturated images while performing sutures.
CONCLUSIONS: Ngenuity digital filters have the potential to enhance tissue visualization during cataract and corneal surgeries, especially in poor visibility conditions.

摘要：
目的：描述Ngenuity3D数字滤波器在白内障和角膜移植手术中增强可视化的优势。
方法：所有手术均由同一经验丰富的外科医生（L.M.）使用连接到显微镜的Ngenuity3D抬头可视化系统进行。在以下每个阶段，使用和不使用过滤器同时捕获图像：内皮评估，撕囊术,胶囊破裂，玻璃体渗漏,去皮层,粘度去除，角膜缝合线,式修辞学，DMEK移植物准备和插入。
结果：在白内障手术中，绿色和单色过滤器通过突出前囊来促进困难情况下的撕囊术，并可以改善后囊撕裂的可视化。单色滤光片的增强的对比度对于皮质和粘弹性去除也是有用的。在角膜手术中，绿色滤光片在组织制备过程中突出显示DMEK移植物的边缘，黄色滤光片增强了前房中染色的DMEK移植物的对比度，单色滤镜通过改善Descemet/内皮层的可视化简化了desemetorexis，并在执行缝合时允许在红色饱和图像中更好地查看。
结论：Ngenuity数字滤波器有可能增强白内障和角膜手术期间的组织可视化，尤其是在能见度差的情况下。
