Treatment of trichiasis with a lid cryoprobe.
A series of 112 eyelids with symptomatic aberrant eyelashes were treated by cryotherapy using a specially designed large-surfaced high-flow nitrous oxide probe. Either thermocouple control to -20 degrees C or timing of the application to 20 seconds (lower lid) or 25 seconds (upper lid) was used to monitor the freeze. Both techniques obtained a high cure rate and a low incidence of complications.
