Purpose
To describe the incidence and characteristics of negative dysphotopsias (ND) as well as the risk factors contributing to it.
Setting
1. Clinic Hietzing, Department of Ophtalmology
2. Karl Landsteiner Institut for Quality Improvement in Cataract Surgery
Methods
For this retrospective study, data from patients who underwent cataract surgery between January 2018 until December 2019 at our Department was analysed. A total of 8122 eyes had cataract surgery performed. Three different IOLs have been used (EyeCee® One by Bausch + Lomb, TECNIS® by Johnson & Johnson, HOYA Vivienx ™ by HOYA). Data from patients who complained about negative dysphotopsia postoperatively as well as data from a gender matched control group was further analysed: pupil size, axial length, anterior chamber depth, angle kappa, IOL power and other biometrical factors.
Results
An incidence of about 1,99% of negative dysphotopsia overall and an incidence of about 1.58% of transient negative dypshotopsia cases and an incidence of 0.42% of persistent negative dysphotopsia cases was found. The average duration of the symptoms was 5.40 (±6.148) weeks. The only risk factor that was found to be statistically significant was the anterior chamber depth (ACD) (p=0.033)
Conclusions
According to our findings a deeper anterior chamber poses a risk for the development of ND.
