Treatment of trichiasis and distichiasis by eyelash trephination.

PURPOSE: To describe the methods and results of a new technique of eyelash trephination for treatment of trichiasis and distichiasis.

METHODS: The medical records of all patients who underwent eyelash trephination by the authors to treat trichiasis or distichiasis were reviewed. Gender, diagnosis, number of eyelids treated, follow-up time, and surgical outcome were recorded. The technique involves boring of the affected lash follicle with a microtrephine, followed by removal of the follicle.

RESULTS: The procedure was performed on 41 eyelids of 26 patients (15 females and 11 males). Patients were followed for 6 to 51 months after surgery. No recurrence was observed in 16 patients (62%) during this period. There were no adverse effects of the therapy.

CONCLUSIONS: Eyelash trephination is a safe, quick, and effective method of treatment for trichiasis and distichiasis.
