About

Nicolas R. Sarfaraz is a pioneering researcher at the intersection of ophthalmic surgery and robotics, whose work is transforming the precision and safety of corneal transplantation. His primary research areas include optical coherence tomography (OCT)-guided surgical techniques and robotic-assisted ophthalmic procedures. Sarfaraz’s major contribution is the development of the OCT-guided Big Bubble technique for Deep Anterior Lamellar Keratoplasty (DALK), a highly challenging cornea transplant procedure that requires precise separation of corneal layers while preserving Descemet’s membrane. His landmark 2020 paper, cited 18 times, demonstrated this technique’s feasibility and reproducibility, offering surgeons a safer, image-guided alternative to traditional manual methods. Building on this, his 2019 work introduced a novel robotic device for autonomous needle insertion in DALK, achieving OCT-sensor-guided hydro-dissection with unprecedented accuracy. This robotic platform, cited 7 times, represents a significant step toward automating complex microsurgical tasks, reducing surgeon variability and patient risk. Sarfaraz’s innovations are particularly impactful for training and standardizing DALK, a procedure known for its steep learning curve. His work has been recognized for bridging imaging, robotics, and clinical ophthalmology, positioning him as a key figure in the future of computer-assisted eye surgery.
