Abstract

The posterior chamber intraocular lens(PC-IOL) implantation is the most effective method for adult cataract. In children, however, its use and effectiveness are still being debatd. To investigate the effect of PC-IOL implantation in unilateral pediatric cataracts, we analysed the results of visual acuities and refractive powers, the presence of complications, and the differences according to the types of posterior capsulectomy in 16 eyes of 16 children who underwent PC-IOL implantation and amblyopia treatment for unilateral pediatric cataracts. Postoperatively, nine eyes(56.3%) showed an improvement of visual acuities more than two lines on Han`s visual acuity chart. Average difference between target which was adjusted to the fellow eye and postoperative refractive power is -0.68diopters after at least 8 months follow-up. Four eyes in which had an intact capsule after surgery or were underwent posterior capsulectomy developed after-cataract, but not in eyes underwent posterior capsulectomy and anterior vitrectomy simultaneously. In unilateral pediatric cataracts, PC-IOL implantation, posterior capsulectomy, and anterior vitrectomy may give a good result for visual rehabilitation but the follow-up is necessary to evaluate the long-term safety.
