    Illustration of ab interno IOL fixation. Double-armed sutures are secured to the eyelets of the IOL haptics. The needles are passed under the iris to exit the eye 1.5 mm posterior to the limbus under the scleral flaps. After the IOL is internalized, the sutures are tightened to center the IOL and tied under the scleral flaps.
