One of the most common causes of lower lid ectropion is horizontal lid laxity, the incidence of which increases with age. This condition induces poor ocular surface tear film coverage which leads to irritation, tearing, and keratopathy. Lateral tarsal strip fixation is the technique which is widely used to repair involutional ectropion due to horizontal lid laxity. Medial spindle procedure is the well-known technique for puntal ectropion correction. Both surgeries are minimally invasive, simple and effective.
