Trichiasis is a lid margin disorder in which the eyelashes are misdirected toward the ocular surface. It is a major cause of ocular morbidity. Trichiasis is secondary to inflammation and scarring of the eyelash follicles. There is a frequent association between trichiasis and cicatricial entropion and the correct diagnosis is mandatory for a successful treatment. There are several options for the management of trichiasis and the main purpose is to eliminate the anomalous cilia and improve the patient's comfort. Temporary measures include eye lubricants, contact lenses, and mechanical epilation. Surgical treatments have initial success but long-term results are poor and recurrences are frequent. Definitive trichiasis treatments include bipolar electrolysis, radiofrequency ablation, cryotherapy and laser ablation, and surgical procedures. The techniques are described in detail along with possible complications and outcome.
