Clinical outcomes after mix-and-match implantation of diffractive multifocal intraocular lenses with +2.75 and +4.00 diopter add powers

Abstract

Background To evaluate the clinical outcomes of bilateral mix-and-match implantation of diffractive multifocal intraocular lenses (IOLs) with different add powers. Methods We retrospectively reviewed the medical records of 18 patients who underwent bilateral mix-and-match implantation of diffractive multifocal IOLs with different add powers. Multifocal IOLs with add powers of +2.75 diopters (D) and +4.00 D were implanted into the patients’ dominant and nondominant eyes, respectively. At 1 and 3-month postoperatively, monocular and binocular visual acuity was measured using logMAR charts and manifest refraction was performed. Specifically, logMAR charts were used to measure uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and corrected distance visual acuity (CDVA). Defocus curves, contrast sensitivity, and patient satisfaction were assessed at 3-month postoperatively. Results Binocular logMAR measurements (mean ± standard deviation) at 3-month postoperatively were 0.01±0.04 (UDVA), 0.16±0.05 (UIVA), and 0.11±0.07 (UNVA). Postoperative spherical equivalent was -0.43±0.35 D and -0.39±0.21 D in the dominant and nondominant eyes, respectively. Defocus curves showed significant differences between -1.50 and -4.00 D among binocular, dominant, and nondominant eye measurements, except between -2.50 and -3.00 D. Eyes implanted with +2.75 and +4.00 D IOLs showed good contrast sensitivity under photopic and mesopic conditions. Over 80% of patients reported high satisfaction with their near vision. Conclusions Bilateral mix-and-match implantation of diffractive multifocal IOLs with add powers of +2.75 D and +4.00 D showed good near, intermediate, and far vision.

Clinical Outcomes after Mix-and-Match Implantation of Extended Depth of Focus and Diffractive Multifocal Intraocular Lenses

“…The study followed the principles of the Declaration of Helsinki, was approved by the Asan Medical Center Review Board (2017-0713), and registered as a clinical trial (KCT0004111). This study basically shared similar platform with the study regarding mix-and-match implantation of diffractive multifocal IOLs with different diopter add powers performed by our institute [ 7 ].…”
