SYSTEMS AND METHODS FOR TISSUE DISSECTION IN CORNEAL TRANSPLANTS

摘要

A dissection system for corneal transplants includes a housing including a contact side to be positioned against a cornea. The housing includes an interior passageway with an opening at the contact side. The dissection system includes a blade assembly disposed in the interior passageway. The blade assembly includes a first blade and a second blade. The first blade includes a first cutting edge and the second blade includes a second cutting edge. The first blade and the second blade are movable relative to the housing such that the first cutting edge and the second cutting edge extend through the opening of the housing and out of the interior passageway. The first cutting edge produces a first cut in the cornea. The second cutting edge produces a second cut in the cornea. The first cut and the second cut define a volume of tissue for removal from the cornea.
