title: The use of cryotherapy for trichiasis.
abstract: Cryosurgical destruction of aberrant eyelashes was performed on 72 eyelids. Seven of nine failures occurred following major deviation from recommended technique. All but one recurrence were successfully re-treated. Notching of the eyelid was observed in one patient. The technique utilized a nitrous oxide gas-cooled cryoprobe. Tissue temperature was monitored by a subcutaneous microthermocouple in the region of the lash follicle to -20 C in a double freeze-thaw cycle.
