If the number of ingrown eyelashes is small and the eye symptoms are not obvious, surgery may not be needed, e.g. in infants and young children, ingrown eyelashes are often caused by lid entropion (often due to the child’s fat and underdeveloped nasal root, resulting in lower lid ingrown eyelashes or lower lid entropion. The less severe cases can heal on their own with age, so surgery can be avoided. If the impingement touches the eye and causes discomfort such as foreign body sensation, photophobia and tearing, then treatment is required. The treatment depends on the number of ingrown eyelashes and the severity of the symptoms: if the number of ingrown eyelashes is small (Figure 1 below), they can be removed directly with tweezers (this method is simple and easy to use, but the downside is that the eyelashes will still grow backwards); electrolysis can be used to destroy the ingrown eyelash follicles (this requires professional intervention and sometimes requires several iterations to achieve the desired effect) or the follicles can be removed. In cases of ingrown eyelashes (Figure 2 below, the eyelashes touch the eyeball and cause damage to the corneal epithelium, resulting in foreign body sensation, photophobia and tearing), surgery is required to correct the ingrown eyelashes to treat the ingrown eyelashes.
