ABSTRACT
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 study to evaluate the effect of trifocal IOL AcrySof IQ PanOptix® and extended depth of focus intraocular lens (EDOF) Tecnis Symfony® IOL implantation on visual field parameters. 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/- 1.08 dB (p = 0.15); foveal sensitivity was 34.5/33.9 dB (p = 0.41); VFI 98.5/98.4% (p > 0.99); PSD 1.85/1.86 (p = 0.07); and for test duration 305.81/298.36 s (p = 0.35); all respectively. Analysis of pre- and postoperative parameters of trifocal IOL were the rates of change of FN 1.22/1.83% (p = 0.29); FP 1.65/1.48% (p = 0.95); MD - 1.55/- 1.37 dB (p = 0.19); foveal sensitivity 33.9/34.9 dB (p = 0.47); VFI 98.6/98.3% (p = 0.62); PSD 1.58/2.05 (p = 0.02); and test duration 297.17/298.57 s (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.
