Retrospective analysis of negative Dysphotopsia after cataract surgery

Abstract

Purpose: To describe the incidence and characteristics of negative dysphotopsia (ND) as well as the risk factors contributing to it.Methods: In this retrospective study postoperative results of 8122 eyes after cataract surgery were analysed. Three different IOLs have been implanted (EyeCee® One by Bausch + Lomb, TECNIS® by Johnson & Johnson, HOYA Vivienx™ by HOYA). Following parameters were studied: pupil size, axial length, anterior chamber depth, angle kappa, IOL power and other biometrical factors. The scotomas were depicted on a Harms tangent screen.Results: An incidence of 1.99% of ND was found, of which 1.58% was transient and 0.42% persistent. The average duration of the symptoms was 5.40 (±6.15) weeks in the transient ND group. In the total cohort of 8122 eyes, there was no difference in the distribution of implanted IOL types or IOL power; neither played the surgeon a significant role in the development of ND. There was no significant difference between ND and control eyes regarding pupil size, axial length, and angle kappa. The anterior chamber was significantly shallower in the ND group: 5.1 ± 0.58 mm vs. 5.41 ± 0.61 mm (p = 0.03).Conclusion: According to our findings, a shallower anterior chamber poses a risk to the development of ND.
