“…Chhaya et al recently demonstrated that the use of 3D visualization enhances the learning benefit of intraocular ophthalmic surgeries. [5] In our experience, with the NGENUITY 3D visualization system, the physicians in training were able to see exactly what the surgeon was seeing – at the same depth, with the same focus, and with excellent clarity, which was helpful for surgical training.…”

Purpose: To evaluate the feasibility and safety of heads-up three-dimensional (3D) vision system for phacoemulsification and intraocular lens (IOL) implantation surgery. Methods: In this prospective, randomized controlled study, 20 eyes with age-related cataract received phacoemulsification and IOL implantation and were randomly divided into “heads-up” 3D vision group and conventional surgery group. Ocular and surgical parameters such as surgery time, pre and postoperative best-corrected visual acuity (BCVA), and corneal endothelial cells density were recorded and statistically analyzed. Results: The result showed significant postoperative improvement of BCVA in both groups. There was no difference in either mean surgery time or postoperative mean endothelial cell density between the 3D group and the conventional group. No major complication occurred during surgery in either group. Conclusion: The heads-up 3D vision system is suitable and safe for cataract phacoemulsification and IOL implantation. This technique can be of widespread use.

Purpose:To compare clinical outcomes of patients undergoing macular hole surgery with heads-up three-dimensional (3D) viewing system and conventional microscope.Methods:In all, 50 eyes of 50 patients with stage 3 or 4 macular hole were randomized and macular hole surgery [inverted internal limiting membrane (ILM) flap technique] was performed in 25 eyes using 3D viewing system and 25 eyes using conventional microscope. All surgeries were performed by a single surgeon. Patients were followed up for a period of 3 months. Logarithm of the minimum angle of resolution (logMAR) visual acuity, macular hole index, intraoperative parameters such as total surgical time, total ILM peel time, number of flap initiations, duration of Brilliant Blue G dye exposure, illumination intensity, postoperative logMAR visual acuity, and macular hole closure rates were recorded and compared between the two groups.Results:The mean age was 67.92 ± 7.95 and 67.96 ± 4.78 years in both groups, respectively (P = 0.98). Gender (P = 0.38) and right versus left eye (P = 0.39) were also comparable. Preoperative and postoperative best-corrected visual acuity (P = 0.86, 0.92), macular hole index (P = 0.96), total surgical time (P = 0.56), total ILM peel time (P = 0.49), number of flap initiations (P = 0.11), and macular hole closure rates (P = 0.61) were not statistically significant when compared between the two groups. Illumination intensity of microscope (100% vs 45%) and endoillumination (40% vs 13%) were significantly less in the 3D viewing system.Conclusion:The clinical outcomes of macular hole surgery using 3D viewing system are not inferior to that of conventional microscopes, and it has the added advantages of better ergonomics, reduced phototoxicity, peripheral visualization, magnification, and less asthenopia, and it serves as a good educational tool.

“…The 3D visualization system has many benefits over the traditional optical microscope. The most significant benefits particular to this procedure are the use of lower illumination levels [ 12 ], improved depth of field [ 13 ], excellent trainee and staff viewing [ 14 ], ergonomics [ 15 ], high recording quality, and more efficient and shorter cases compared to using an indirect ophthalmoscope [ 10 ].…”

Background Visualization during scleral buckling is traditionally achieved via indirect ophthalmoscopy. Recent advances have utilized the surgical microscope and a 25 gauge cannula-based endoillumination system, also known as a Chandelier lighting system. This report details an improved approach using a guarded 25 or 27 gauge light pipe and the Ngenuity digital three dimensional platform. Methods A standard Alcon light pipe is modified with a silicone guard to expose only 5 mm of the tip of the light pipe. The guard is created from the silicone that is already opened to secure the ends of the encircling band most often employed sleeve (e.g. 70, 270). This guarded light pipe is then inserted into the cannula as an alternative to a Chandelier lighting system. Results This is a technical report of a surgical visualization technique using a three dimensional digital visualization platform with a modified handheld vitrectomy light pipe. Conclusion The utilization of a guarded light pipe for visualization during primary scleral buckling is a promising, effective, and efficient technique. The three dimensional digital display allows for better educational impact and surgical communication with trainees and ancillary members of the surgical team.
