Abstract Details


We aimed to evaluate the long-term refractive changes in pediatric patients underwent developmental cataract surgery with primary intraocular lens (IOL) implantation.


Ege University Faculty of Medicine, Ophthalmology Department


A total of 42 eyes of 26 patients between 2 and 13 years old who underwent cataract surgery with primary posterior chamber IOL implantation and followed-up for at least 5 years postoperatively were retrospectively evaluated. The age at the time of surgery, pre and postoperative oculobiometric measurements as axial length and keratometric data, and any accompanying ocular pathologies or additional operation were obtained from the patients’ charts. The mean refractive changes and the amount of refractive change per year were analyzed.


The average age at the time of surgery was 66.9±35.3 months and the average follow-up period was 83±28.6 months. Children operated on at 2 to 3 years of age had a mean myopic shift of -5.02±2.3 diopters(D) with a mean -0.73±0.24 D of refractive change per year; 3 to 5 years old demonstrated a mean -0.38±0.19 D and 5 to 7 years old experienced a mean -0.37±0.2 D of refractive change per year. Children older than 8 years at the time of operation had a mean myopic shift of -1.4±1.1 D with -0.22±0.15 D of mean refractive change per year.


The postoperative myopic shift and the mean refractive change per year in pediatric patients undergoing IOL implantation decreased as patient’s age increased. The greatest change occurred between 2 and 3 years of age and persists until at least 13 years of age. However the postoperative refractive changes are variable, and estimating the time of refractive stabilization for an individual patient is difficult.
