Argon laser treatment of trichiasis

Abstract

The argon laser was used to treat trichiasis in 44 patients over a five-year period. During follow-up intervals of between one month and more than four years (mean, 13 months), ablation of misdirected cilia was accomplished with one treatment in 26 patients (59%). No complications were observed. Laser is less effective than cryotherapy for destroying aberrant eyelashes, but cryotherapy is less precise and incites greater posttreatment inflammation. Argon laser treatment is a useful option when only a few, scattered eyelashes require ablation or in patients with disorders such as ocular pemphigoid, in which the stimulation of inflammation is undesirable.
