Clinical and Visual Outcomes of Four Presbyopia Correcting Intraocular Lenses

Abstract

Purpose: To compare objective and subjective outcomes of the multifocal intraocular lenses ReSTOR SN6AD1 and Tecnis ZKB00, extended depth of focus IOL Symfony ZXR00, and trifocal IOL PanOptix TFNT00. Methods: This study included 262 patients (524 eyes) who had phacoemulsification with IOL implantation, 128 eyes with SN6AD1, 124 eyes with ZKB00, 136 eyes with ZXR00, and 136 eyes with TFNT00. Objective outcomes included one-month postoperative uncorrected (U) and corrected (C) distance (D) and near (N) visual acuities (VA). Subjective outcomes included photic phenomena, spectacle use, and spectacle-independent visual function. Results: Spectacle use (%) in the SN6AD1, ZKB00 ZXR00, and TFNT00 groups was 39, 64, 87, and 37 respectively (P < 0.0001). Presence of photic phenomena (%) for SN6AD1, ZKB00, ZXR00, and TFNT00 was 66, 61, and 67, and 73, respectively (P = 0.57). Spectacle-independent mean VF- 14 score (%) for SN6AD1, ZKB00, ZXR00, and TFNT00 was 89.5, 87.2, 80.9, and 83.6, respectively (P < 0.01). Conclusion: All four IOLs provided excellent postoperative visual acuity and equally high rates of photic phenomena. SN6AD1 and TFNT00 provided the least spectacle use while ZXR00 had the highest spectacle use.
