A Study on Visual Outcome after Intraocular Lens Implantation (IOL) in Children with Traumatic Cataract

Abstract

Aim: To assess the final visual outcome after Intraocular Lens (IOL) implantation in children with traumatic cataract. Materials and Methods: Retrospective study, Twenty five children with traumatic cataract age ranging from 2 years to 14 years over the period of two years were selected after fulfilling the inclusion criteria. A thorough systemic and ocular examination was carried out.  This included recording of visual acuity, anterior segment examination, slit lamp biomicroscopy, tonometry, posterior segment evaluation with B-scan ultrasonography.IOL power, Keratometry was done with the help of Keratometer (KM- 500, NIDEK) and IOL power was calculated with the help of A-scan (Alcon, Ocuscan) using Sanders Retzlaff Kraff (SRK) –II formula and IOL Master (Carl Zeiss Meditec. AG). Results: 19 (76%) male and 6 female (24%).14 patients (56%) were suffered from penetrating injury, of this 10 (71.4%) were male, 4 (28.6%) were female. There were 11 patients (44%) who suffered blunt injury of this 9 (81.8%) were male and 2 (18.18%) were female. Most common mode of penetrating injury was by stick. Preoperative visual acuity was < 1/60 in 20 cases (80 %). The final visual outcome with the best correction was 6/6 in 4 (16 %) cases (3 in blunt, 1 in penetrating), 6/9 in 4 cases (16%) cases. CONCLUSION- intraocular lens implantation in children has a  role in treating aphakia, resulting in good visual outcome and binocularity.
