Disclosed is a corneal excision or scoring device. In one embodiment, the device includes a stabilizing portion having a first opening adapted to encircle an eye, such that at least a portion of the stabilizing portion engages the conjunctival fornix of the eye when inserted. The device may also include a second opening adapted to receive a cutting portion having a cutter capable of cutting or scoring the eye. In another embodiment, the device includes a stabilizing portion having an interior with a stop and an exterior serrated edge formed from a plurality of teeth. The stabilizing portion becomes inserted in an eye, such that the serrated edge rests on a sclera of the eye. Next, a cutting portion becomes inserted into the stabilizing portion to cut or score the eye, and the stop limits the distance the cutting portion may be inserted. Related methods are also disclosed.
