To assess the indications, compare pre and postoperative visual acuity and to assess the complications following intraocular lens exchange in a pediatric population.
Faculty of Medicine AIN Shams Univeristy Cairo Egypt and also Magrabi Hospital KSA
Medical records of children less than 15 years who had undergone intraocular lens exchange from Jan 2008 to Jan 2009 were retrospectively reviewed. The parameters studied included age, sex, pre and post operative visual acuity and refraction and indication for intraocular lens exchange .Inclusion criteria was a minimal period of six month follow up following surgery. All patients were operated on by a single experienced surgeon.
11 eyes of 10 children were studied. Mean age of the study population was 8 years (range 3 to 13).Male to female ratio was 1:1. Indications for surgery included posterior capsular opacification with optic capture (54%), decenteration of lens (18%), myopic shift (9%), lens pitting (9%) and sequelae of post operative inflammation (9%). Wilcoxon signed rank test was used to compare the pre and post operative best corrected visual acuity which showed a statistically significant improvement (Post op day 1 - p value 0.11 and 1 month post op p value 0.005). 4 cases with poor vision after surgery were due to cystoids macular edema (9%) and amblyopia due to PHPV (9%) and nystagmus (18%).
ugh technically challenging, intraocular lens exchange can be a visually rewarding procedure in experienced hands.
