Three-dimensional digital visualization of phacoemulsification and intraocular lens implantation

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.
