Based on clinical slitlamp observations, the intraocular lens (IOL) optics do not touch the posterior capsule in the eye with the ring. Therefore, we can conclude that the IOL optics do not play any part in preventing posterior capsular opacification (PCO). The main purpose of our study1 was to determine the effect of the endocapsular equator ring (E-ring) on preventing PCO. We did not need to perform a postoperative posterior capsulotomy in any eye with an E-ring, which is a definitive result. Because of this, we did not investigate the materials and shapes of the IOLs implanted in the control eyes. We would like to leave that study of the IOLs to other researchers.
