Posterior-capsule opacification, by far the most common complication of primary cataract surgery, continues to stimulate important work toward understanding its causes, preventing it, and effectively treating it. Of special note here are a report by Koch and Kohnen that a combination of vitrectomy and posterior capsulorhexis is required to inhibit posterior-capsule opacification in pediatric patients; work by Nishi et al. toward the dream of replacing the cataractous lens with a flexible artificial lens, supported by the natural capsular bag; and methods by Tetz et al. and Pande et al. for precise quantification of posterior-capsule opacification.
