Clinical outcomes with a low add multifocal and an extended depth of focus intraocular lenses both implanted with mini-monovision

Objectives To compare the visual acuity, contrast sensitivity (CS), spectacle needs, photic phenomena, and quality of life parameters of patients bilaterally implanted with a low add multifocal (MIOL) or an extended depth of focus (EDOF) intraocular lens (IOL), both with intended mini-monovision.

Description
Summary:Objectives To compare the visual acuity, contrast sensitivity (CS), spectacle needs, photic phenomena, and quality of life parameters of patients bilaterally implanted with a low add multifocal (MIOL) or an extended depth of focus (EDOF) intraocular lens (IOL), both with intended mini-monovision. Methods In this prospective, randomized, comparative study, patients were randomized to receive either Tecnis +2.75 D (ZKB00) (MIOL Group, n  = 15) or Tecnis Symfony (ZXR00) (EDOF Group, n  = 14) for bilateral implantation with mini-monovision (−0.50 D). Binocular logMAR uncorrected visual acuities (UVA), monocular defocus curves, CS with CSV 1000-E, and Pelli-Robson Test (PRT), spectacle needs and quality of life parameters with NEI RQL-42 questionnaire were evaluated at postoperative 1, 3, and 6 months. Results Results of MIOL and EDOF Groups at postoperative month 6 are as follows: distance (6 m) UVA −0.03 ± 0.05 and −0.05 ± 0.06 ( p  = 0.938), intermediate (60 cm) UVA, 0.04 ± 0.08 and −0.03 ± 0.07 ( p  = 0.046); near (40 cm) UVA, 0.22 ± 0.08 and 0.15 ± 0.07 ( p  = 0.046); near spectacle needs, 26.7% and 14.3% ( p  > 0.05), respectively. Better visual acuity was achieved in the EDOF Group between the defocus range of −0.50 and −1.75 D ( p
