ABSTRACT:
An apparatus for preserving and conducting chemical tests on corneal tissues. The apparatus consists of a chamber having a medial portion with a port therethrough. Operatively attached to the port is a system for retaining the cornea in position. Placed over the port and in direct contact with the cornea is a cover member of non-abrasive, biologically compatible material. A nutrient supply conduit delivers liquid nutrients to the cover member from an external source. The nutrients are imparted to the cornea through direct contact between the cornea and the cover member. Residual nutrients are collected in a reservoir secured to the chamber beneath the port. The reservoir is drained using a waste conduit. Also, the chamber is filled with nutrients so that the inner surface of the cornea is sustained. As a result, the corneal tissues are maintained in a living state.
