Incidence and Prognostic Factors for Visual Outcome in Patients Having Cataract Surgery with Traumatic Cataract Visiting Tertiary Care Centre, Jharkhand

ABSTRACT

Introduction: Ocular trauma is one of the common causes ofvisual morbidity. This study aims to investigate the incidenceand prognostic factors for visual outcome in patients withtraumatic cataract following cataract surgery.Material and methods: This prospective hospital-basedstudy was performed in a tertiary care centre of Jharkhandbetween February 2019 to February 2020. All patientswho underwent cataract surgery with or without primaryintraocular lens implantation with traumatic cataract wereevaluated. Age, sex, preoperative vision, postoperative visionat 3 – 6 months, Injury type, wound location and posteriorsegment involvement responsible for poor visual outcomewere assessed.Results: Forty seven eyes of 47 patients were studied whichincluded 42 males and 5 females. In 32 patients right eye andin 15 patients left eye was involved. The preoperative visualacuity in all 47 eyes was less than 6/60. The postoperativevisual acuity in 25 eyes was 6/6 – 6/18, 14 eyes had visualacuity of 6/24 – 6/60 and 8 eyes had visual acuity less than6/60. Corneal opacity and posterior segment involvementwere the main causes of poor visual acuity.Conclusion: The prognostic factors like initial visual acuity,injury type, wound location and posterior segment involvementplayed a vital role in achieving final visual acuity. Our studyalso shows that satisfactory visual results can be achieved inthe absence of posterior segment involvement and cornealscar not obscuring the visual axis.
