Clinical study of the secondary posterior chamber intraocular lens implantation in congenital cataract

Objective To study the effectiveness and technique of secondary posterior chamber intraocular lens implantation in congenital cataract. Methods The posterior chamber intraocular lens was implanted secondarily in 36 aphakic eyes of congenital cataract. Nine eyes with the trans-scleral fixation of posterior chamber intraocular lens. Relative operations before IOL implantation in clued pupilary menbrinectomy,pupilloplasty,posterior synechialusis and so on. Results All eyes achieved a postoperative corrected visual acuity equal to or better than that of the corrected visual acuity before the surgery. There are no serious complications. Conclusion Secondary posterior chamber intraocular lens implantation is a safe and effective method in children over two years old with aphakics.
