Comparative study of visual outcome of newly designed scleral tuck lens and suture-fixated lens for rehabilitation of aphakia in various aetiologies

Abstract

Purpose: Visual rehabilitation in aphakia can be performed using several modalities. However, these modalities could be either technically difficult or expensive. Herein, we developed a scleral tuck lens to provide a simple and cost-effective solution for aphakia and compared its outcome with standard methods. Methods: A specially designed posterior chamber self-sustaining lens was implanted in patients with aphakia without capsular support because of different primary etiologies. The visual outcomes, as well as intraoperative and postoperative complications, were examined. The data were retrieved from electronic medical records, and visual outcome and complication rates were compared. The outcomes were also compared according to the etiology and age groups (pediatric and adults). Results: We found significant improvement in preoperative and postoperative visual outcome. We did not find any significant difference in visual outcome amongst suture-supported scleral fixated lens with scleral tuck lens. Conclusion: Satisfactory visual outcomes were noted with minimal complications; and comparable with gold standard suture fixated lens, however long-term follow-up is required.
