This study analyzes the results of cataract surgery with primary intraocular lens implantation in
unilateral childhood traumatic cataract following penetrating trauma and its long term follow up.
It is a hospital based study of 114 children (age 3-10 years) with unilateral traumatic cataract who
underwent extracapsular cataract extraction/ lens aspiration with implantation of posterior chamber
intraocular lens (IOL). Primary posterior capsulotomy (PPC) was performed in 57 eyes and the rest
57 were without PPC (NPPC). The patients were followed up at regular intervals for a period of 3
years.
Postoperative inflammation and pupillary capture were two frequent complications seen during
postoperative period. Development of posterior capsular opacification (PCO) was 1/57, 4/57 at 8th
week and 7/30 and 14/39 at 6 months, in PPC and NPPC group, respectively. Best corrected visual
acuity (BCVA) ≥ 6/18 was achieved in 50% of eyes at 8th week post operatively and the same at 3
years with/without membranectomy/capsulotomy was evident in 73.3% of eyes.
Meticulous case selection with insersion of “in the bag IOL†and subjecting the traumatized
cataractous eyes to primary posterior capsulotomy are factors responsible for optimal outcome in
unilateral traumatic cataract in children.
