If trichiasis affects vision, it indicates that the abrasion of the cornea by the eyelashes has reached a certain degree, and active treatment is necessary. The main goal of the treatment is to prevent the future formation of corneal haze, spotted haze, or leukoma, which can severely impact vision. With active treatment, these conditions generally do not develop, so although trichiasis is a minor condition, if not treated actively, it can lead to serious complications. The primary treatments for trichiasis involve the use of eye drops, such as levofloxacin eye drops and sodium hyaluronate eye drops. If the number of misdirected lashes is small, electrolysis of the eyelashes can be performed. If there are many, surgical treatment may be necessary to correct the inward turning of the eyelid. With active treatment, complete recovery is generally possible. (Please use medication under the guidance of a doctor.)
