Scleral fixation of IOLs is one of the modalities adopted for secondary IOL fixation, and good results have been reported with this method. Every surgery has its pros and cons, including scleral-fixated IOLs. Suture-related complications have been reported, and to avoid erosion of the knots through the conjunctiva, scleral flaps to cover the knots or rotation of the sutures into scleral tissue without flaps have been recommended. Steady traction on transscleral sutures secures the IOL insertion into the ciliary sulcus. Due to the atrophy of scleral flaps over time, the suture end often gets exposed, causing granuloma formation and increased risk of infection.
