Longitudinal Evaluation of Trifocal and Extended Depth of Focus Lenses Implantation using Standard Automated Perimetry Parameters

Purpose: To evaluate reliability and global indices parameters from standard automated perimetry (SAP) in normal eyes undergoing phacoemulsification cataract surgery with implantation of trifocal or extended depth of focus intraocular lens (IOL).Methods: Prospective comparative study. Comparison of trifocal IOL AcrySof IQ PanOptix® and extended depth of focus intraocular lens (EDOF) Tecnis Symfony® IOL. Patients underwent SAP pre- and postoperatively. Reliability indices (false negative rate - FN, false positive rate – FP), global indices (foveal sensitivity threshold, visual field index - VFI, standard pattern deviation – PSD, mean deviation MD) and test duration were analyzed.Results: A total of 23 eyes from 13 patients were in the trifocal IOL group and a total of 22 eyes from 14 patients were in the EDOF group The following results were obtained by analyzing pre- and postoperative SAP of EDOF IOL: the rate of change of FN was 1.95/1.41% (p=0.61); FP 1.64/1.27 (p=0.60); MD -1.60/-1.08dB (p=0.15); foveal sensitivity was 34.5/33.9dB (p=0.41); VFI 98.5/98.4% (p>0.99); PSD 1.85/1.86 (p=0.07); and for test duration 305.81/298.36s (p=0.35); all respectively. Analysis of pre- and postoperative parameters of trifocal IOL was: the rates of change of FN 1.22/1.83% (p=0.29); FP 1.65/1.48% (p=0.95); MD -1.55/-1.37dB (p=0.19) ; foveal sensitivity 33.9/34.9dB (p=0.47) ; VFI 98.6/98.3% (p=0.62); PSD 1.58/2.05 (p=0.02); and test duration 297.17/298.57s (p=0.87); all respectively. Conclusion: We identified a change in the PSD parameters in the trifocal IOL group. No other significant changes were identified in SAP parameters after implantation of trifocal AcrySof IQ PanOptix® and EDOF Tecnis Symfony® IOL. Longitudinal evaluation showed no changes in SAP after Trifocal and EDOF IOL implantation in normal subjects.
