Surgical technology update for ophthalmic surgery: heads-up display, artificial intelligence, instrumentation, and robotics

PURPOSE OF REVIEW: Rapid advances in surgical visualization, microsurgical instrumentation, artificial intelligence (AI), and robotic assistance are reshaping ophthalmic surgery. This review evaluates current clinical and experimental evidence to determine how these technologies influence surgical efficiency, precision, safety, and patient outcomes. RECENT FINDINGS: Three-dimensional (3D) heads-up display systems (HUDS) subjectively improve surgeon ergonomics and permit lower illumination levels while maintaining complication rates equivalent to conventional microscopy. Advances in surgical instrumentation, including smaller-gauge vitrectomy systems, high-speed cutters, preloaded intraocular lens (IOL) delivery systems, and device-based glaucoma implants demonstrate gains in operative efficiency without compromising anatomic success. AI-based systems enable automated surgical phase recognition, real-time instrument tracking, and outcome prediction with high accuracy. Robotic platforms offer the promise of sub-millimeter instrument stabilization and feasibility of high-precision maneuvers across ophthalmic subspecialties. SUMMARY: Emerging technologies have enhanced technical performance in ophthalmic surgery. However, most demonstrated benefits concentrate on ergonomics, workflow efficiency, and motion stability, with fewer studies showing consistent improvements in long-term clinical outcomes. Larger multicenter trials are needed to define true clinical value, cost-effectiveness, and optimal clinical integration.
