Abstract

Introduction: To assess long-term outcomes of implantation of black diaphragm intraocular lens (BD IOL) in post-traumatic aniridia and aphakia due to eye rupture. Methods: This is a retrospective consecutive case series of 14 eyes with post-traumatic complete aniridia and aphakia treated with scleral fixation BD IOL. Measurements included ophthalmological comorbidities, best corrected visual acuity (BCVA), complications, and postoperative interventions. The average postoperative follow-up period was 36 months. Results: BCVA improved in 6 cases, was stable in 6 cases and worsened in 2 cases. The lens was well centered in 13 cases. Glaucoma was diagnosed in six cases developed, and three of them required Ahmed valve implantation. One lens developed opacity. The cornea was decompensated in 6 cases, while two of them required penetrating keratoplasty. Conclusion: Implantation of BD IOL in eyes with severely traumatized eyes enables reconstruction of the anterior segment and some functional restoration, although many complications may arise during the longitudinal follow-up.

We describe our experience in a series of 14 cases with posttraumatic aniridia and aphakia due to eye rupture managed with secondary implantation of the BD IOL
best corrected visual acuity (BCVA) was no light perception in one eye, light perception in 4 eyes, hand movement and 0.02

Summary

Introduction

To assess long-term outcomes of implantation of black diaphragm intraocular lens (BD IOL) in post-traumatic aniridia and aphakia due to eye rupture. Eyeball rupture is the most devastating type of open-globe injury caused by a blunt object leading to sudden increase of intraocular pressure and disruption of the wall of the eye globe [1]. It often results in both aniridia and aphakia, in addition to vitreous haemorrhage and retinal detachment [2]. This condition is usually primarily treated by the corneal and scleral suturing, followed by secondary lens extraction, pars plana vitrectomy (PPV), and retinal reattachment to keep the eyeball complete.
