Open the CIPO recordAbstract From the Canadian patent
A corneal holder amenable for use in both a, corneal storage system and a corneal cutting system with minimal physical manipulation of the corneal tissue itself. The holder provides a passageway through the apertures of both a base member and a cap member that is configured to allow a cutting device to be passed into cutting contact with a predetermined portion of the corneal tissue. The holder allows radial orientation of the predetermined portion in order to limit astigmatism; as well as constriction of the periphery of the corneal tissue during storage in order to alleviate swelling of the tissue due to fluid absorption.
