Influence of Visual Field on Visual Acuity and Contrast Sensitivity in Open-Angle Glaucoma Eyes with Monofocal and Extended Depth-of-Focus Intraocular Lenses

Abstract

Abstract Introduction The aim of this prospective and comparative study was to investigate the association of perimetry parameters on visual acuity and contrast sensitivity in primary open-angle glaucoma (POAG) eyes with diffractive extended depth-of-focus (EDoF) and monofocal intraocular lenses (IOLs). Methods In cataract eyes with medicinally controlled POAG with no defects in the central visual field and mean deviation (MD) values of − 10 dB or better, EDoF and monofocal IOLs with the same platform except for echelette optics for EDoF were implanted in 22 and 24 eyes, respectively. Corrected distance visual acuity (CDVA), contrast sensitivity at 3 to 18 cycles per degree (cpd), and automated perimetry using 30-2 and 10-2 Swedish Interactive Threshold Algorithm programs were examined 3 months postoperatively. The influences of perimetry parameters including MD, foveal sensitivity (FS), and the means of the central four points (central MD and central FS) on CDVA and contrast sensitivity were evaluated using linear and multiple regression analyses. Results In POAG eyes with EDoF IOLs, contrast sensitivities at 12 and 18 cpd were associated with 30-2 and 10-2 perimetry parameters. In POAG eyes with monofocal IOLs, associations of 30-2 parameters were found in CDVA and 3-cpd contrast sensitivity. Conclusions The visual function of POAG eyes with EDoF IOLs was associated with perimetry parameters in high spatial frequency contrast sensitivity, which was different from that of POAG eyes with monofocal IOL.
