This leaflet explains trichiasis, a condition where eyelashes turn inward and scratch the surface of the eye, often due to scarring from infections like trachoma. If left untreated, trichiasis can lead to corneal scarring and blindness. However, blindness is preventable with early surgery. The recommended treatment is a simple lid rotation surgery, which can be done in local clinics by trained health workers. Pulling out lashes is not a reliable solution, as they grow back and may cause more damage. Women are especially at risk, and anyone experiencing symptoms should seek prompt care to protect their vision.
