Safety of Primary Intraocular Lens Insertion in Unilateral Childhood Traumatic Cataract

Abstract

This study analyzes the results of cataract surgery with primary intraocular lens implantation inunilateral 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 whounderwent extracapsular cataract extraction/ lens aspiration with implantation of posterior chamberintraocular lens (IOL). Primary posterior capsulotomy (PPC) was performed in 57 eyes and the rest57 were without PPC (NPPC). The patients were followed up at regular intervals for a period of 3years.Postoperative inflammation and pupillary capture were two frequent complications seen duringpostoperative period. Development of posterior capsular opacification (PCO) was 1/57, 4/57 at 8thweek and 7/30 and 14/39 at 6 months, in PPC and NPPC group, respectively. Best corrected visualacuity (BCVA) ≥ 6/18 was achieved in 50% of eyes at 8th week post operatively and the same at 3years with/without membranectomy/capsulotomy was evident in 73.3% of eyes.Meticulous case selection with insersion of “in the bag IOL” and subjecting the traumatizedcataractous eyes to primary posterior capsulotomy are factors responsible for optimal outcome inunilateral traumatic cataract in children.Key words: childhood, intraocular lens, Nepal, traumatic cataract

Factors affecting visual outcome in traumatic cataract and its associated ocular injuries - A hospital based study

“…In our study soft cataract was noticed in 22.5% which is consistent with the study of Shah MA et al in their study showed 59.9% patients had white soft cataract with ruptured anterior capsule followed by 26.6% had total cataract [22]. In our study more than half of patients had pre-treatment best corrected visual acuity of light perception only which is consistent with study of Ahmed N et al [24] where half of patients had visual acuity of hand movement and with study of Kumar S et al [25] where maximum patient had visual acuity of light perception only. In our study, Corneal tear was most common associated ocular damage followed by uveitis, lens matter in anterior chamber.…”

Ocular Trauma Score as a predictor of final visual outcomes in traumatic cataract cases in pediatric patients

“…Many studies document visual outcomes in children with traumatic cataract. Shah et al 4 report that 56% of patients obtained a CDVA of better than 20/60, Krishnamachary et al 12 found a CDVA of better than 20/60 in 74% of cases, and Kumar et al 13 of better than 6/18 in 50% of cases. Staffieri et al 14 report a CDVA of better than better than 0.7 in 27% of cases.…”

Maximizing the visual outcome in traumatic cataract cases: The value of a primary posterior capsulotomy and anterior vitrectomy

“…A similar procedure was performed for treatment of traumatic cataracts by and Kumar et al . [ 16 ] and Rastogi et al . [ 17 ] They reported similar results, but only in pediatric subjects; furthermore, no control group was included.…”
