Forceps are provided for use in removing nuclear fragments of the lens of an eye during eye surgery. It is not unusual during phaco emulsification surgery on the lens of an eye for the capsule of the lens to become torn and for vitreous humor to enter the lens capsule through the tear and engulf the nuclear fragments remaining in the lens to migrate through a tear in the lens capsule into the vitreous humor. The forceps of the invention allow such nuclear fragments to be removed far more easily and with less likelihood of complications than has heretofore been possible. The forceps are formed of a pair of elongated arms at the tips of which tiny hemispherical or oval cup-shaped implements are mounted. These implements are concave at their mutually facing central regions. The perimeters of the implements from cutting edges that are capable of being brought into mutual contact throughout to entrap loose nuclear fragments therebetween.
