title: Cryosurgery for treatment of trichiasis.
abstract: We cryosurgically destroyed eyelashes in rabbits and applied the technique to treat 23 selected patients with trichiasis. Liquid nitrogen was sprayed on the eyelid margin by using a double, rapid-freeze, slow-thaw cycle monitored by a subcutaneous thermocouple to -30 degrees C. It was an improvement on electrolysis and a simple alternative to surgery.
