PURPOSE: 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.
