Abstract
A simplified cryotherapy technique for the treatment of trichiasis and distichiasis is described. The success rate of aberrant lash ablation with 1 treatment was 82%; this was increased to 95% with a repeat treatment. There were minimal long-term side effects. A simplified time-based technique without the use of a thermocouple produced results similar to other series using thermocouple control. A N2O cryo unit was used in a double freeze-thaw cycle to treat the area of aberrant lash growth. The effective times in the double freeze-thaw cycle were 45 s freezing with a 4 min thaw in the 1st cycle and a repeat freezing cycle of 45 s duration.
