[Treatment of trichiasis with high-frequency radio wave electrosurgery]

Trichiasis is an acquired condition in which the eyelashes are directed posteriorly, touching the surface of the cornea. It poses a complex therapeutic problem. Despite several therapeutic options (epilation, electroepilation, cryotherapy, laser ablation and standard surgical techniques), relapse is frequent.

A prospective, nonmasked study was conducted to determine the efficacy of high-frequency radioelectrosurgery for treatment of trichiasis. Thirty-four patients (fifty-four eyelid segments) were treated with this technique. After eight weeks, all patients were reviewed regarding the success rate, relapse and complications.

Cure was achieved after only one session of treatment in twenty-two patients, and two or more sessions in the remaining twelve. No complications have been reported.

We consider high-frequency radioelectrosurgery a simple, not expensive, effective and free of complications technique for the treatment of trichiasis.
