Argon laser treatment of trichiasis

Abstract

This paper presents the application of argon laser in the treatment of trichiasis. The technique involves the destruction of the follicles of the abnormal cilia. A beam of 50- to 200-micron spot size, 0.1- to 0.2 second time, and 1,000 to 1,200 mW power is used under local anesthesia. This method proved safe, convenient, precise, and effective in 11 cases. The technique is most suitable when a few fine cilia are involved, but repeated treatment may be required for more and thicker eyelashes. The follow-up period in this study varied from a minimum of four months to a maximum of nine months.
