The present invention provides a biocompatible Conductive Keratoplasty probe guide device having an arcuate member and at least one orifice capable of allowing the probe to be inserted through the orifice. The distal end carries the thread gauge attached to a motor-driven spindle. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. The segments each have an inner surface, an outer surface, side edges, a front edge, a back edge, and a vane extending from the outer surface. To remove the cap from the valve stem, a key is employed which forms an interference fit with the shoulders in the liner, once exposed.
