The surgical instrument used to enlarge the punctum is a dilator. A dilator is specifically designed to widen or enlarge structures, in this case, the punctum, which is the small opening of the tear duct system in the eye. By using a dilator, a surgeon can carefully increase the size of the punctum, allowing for improved drainage of tears or easier access for further surgical procedures.

In contrast, other instruments like forceps are primarily used for grasping or holding tissue, while clamps serve to occlude or occlude blood vessels or other structures. A keratometer is used to measure the curvature of the cornea in the eye, which is unrelated to the task of enlarging the punctum. Therefore, the use of a dilator is the most appropriate choice for this specific surgical procedure.
