A new cryoprobe for cryocoagulation of the ciliary body was designed, which is cooled by nitrogen and permits defined coagulation of the ciliary body over 120 degrees. The thermodynamic profile of this probe was investigated in a mathematical model and in practical measurements, defining the conditions for an optimum heat transfer.
