Corneal trephine manual instrument (A hand-held, ophthalmic surgical instrument, constructed as a one-piece handle with trephine (not an exchangeable component) that is manually rotated with downward pressure by a surgeon in order to cut and remove circular pieces of corneal tissue (corneal buttons). The trephine portion consists of a shaft that has at its working end an extremely sharp, bevelled, cylindrical cutting edge. Healthy tissue may be taken from cadavers for transplant to the recipient, where the defect cornea is cut and removed for acceptance of the replacement. This is a reusable device.)
