Globe Fixation Under Topical Anesthesia For Beginners

Surgeons often must manage complications relating to poor eye fixation during phacoemulsification under topical anesthesia. In this video, Dr. Soham Basak details a curious observation that globe fixation often improves dramatically after injecting tryphan blue into the anterior chamber. The effect is maintained even after the dye is washed out. Building on that observation, Dr. Basak and his colleagues have discovered that they can achieve a better fixation during surgery by simply attaching a blue LED light to the microscope, and instructing their patients to focus on that light. In especially difficult cases, however, Dr. Basak recommends using a sub-tenon block.
