Thermoablation treatment for trichiasis using the argon laser.
This paper presents a brief review of the literature regarding current treatment modalities for trichiasis and their complications. The technique of Argon laser thermoablation of lashes is described. A total of 12 patients with recurrent trichiasis involving 15 eyelids were treated and the procedure was found to be effective in 12 eyelids (80%). The follow-up period was three to six months. The laser settings used were Argon blue-green wavelength, spot size 50 to 100 microns, exposure time 0.05 to 0.10 seconds and power 1200 to 2000 mW. Advantages of the technique were precise application and selectivity, lack of complications, non-requirement for infiltrative anaesthesia and ease of performance. Disadvantages were the need for up to three treatments in some patients and the technique only being suitable for treating small numbers (up to six) of lashes.
