Abstract
An instrument for facilitating the accurate trephination of donor corneal tissue. The instrument can easily accommodate different sizes of trephines and provides for proper and accurate positioning of the donor tissue to ensure a proper central cut of the tissue. The instrument utilizes an integral base and stand that supports a moveable piston which drives the trephine through the tissue carried by a cutting block supported on the base.
