In brief: Multiple ways
General anesthesia, local anesthesia with peribulbar or subtenon's "block, " or topical anesthesia and holding your eye still with forceps or traction sutures.
A speculum is used to keep your lids open, and rarely may involve a facial nerve block to help prevent squeezing. Small micro-saccades can be compensated for. But any large eye movements are even more magnified under the microscope.
