ABSTRACT:
A host cornea marking device for providing marks on a recipient cornea bed of a corneal transplant patient is disclosed. The present marking device includes: an outer tube having a plurality of marking blades at one of opposite axial ends thereof which is adapted to face the recipient cornea bed, the marking blades being spaced apart from each other in a circumferential direction of said outer tube; and an inner tube which is received in the outer tube, such that the inner tube is axially slidable relative to the outer tube. The inner tube includes a contact portion at one of opposite axial ends thereof which is adapted to be in contact with the cornea bed so as to position the marking device with respect to a cutout section in the recipient cornea bed for receiving a donor cornea. A spring between the inner and outer tubes may be used to hold the inner tube in a first position.
