Comparison of Visual Outcomes and Patient Satisfaction After Bilateral Implantation of an EDOF IOL and a Mix-and-Match Approach.

Abstract

PURPOSE:

To evaluate visual outcomes at different distances (near, intermediate, and far), depth of focus, optical quality, quantitative dysphotopsia, and patient satisfaction in two groups.

METHODS:

The extended depth of focus (EDOF) only group (n = 40 eyes) was implanted bilaterally with an EDOF intraocular lens (IOL) and the mixed group (n = 40 eyes) was implanted with the same EDOF IOL in the dominant eye and a trifocal IOL in the fellow eye. At the 3-month postoperative visit, refractive outcomes and monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance visual acuities for far UDVA, CDVA, distance-corrected intermediate visual acuity (DCIVA) at 80 cm, uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA) at 40 cm, and binocular defocus curve were evaluated.

RESULTS:

The mean spherical equivalent (SE) 3 months postoperatively was -0.16 ± 0.41 diopters (D) in the EDOF only group and -0.39 ± 0.63 D in the mixed group. In the EDOF only group, binocular visual acuities were: UDVA = -0.04 ± 0.07 logMAR (20/18); CDVA = -0.04 ± 0.06 logMAR (20/18); DCIVA (80 cm) = 0.07 ± 0.19 logMAR (20/23); DCNVA (40 cm) = 0.32 ± 0.15 logMAR (20/42); and UNVA (40 cm) = 0.24 ± 0.17 logMAR (20/35). In the mixed group, binocular visual acuities were: UDVA = 0.03 ± 0.09 logMAR (20/21) (P = .08); CDVA = -0.01 ± 0.07 logMAR (20/20) (P = .25); DCIVA (80 cm) = 0.24 ± 0.23 logMAR (20/35) (P = .08); DCNVA (40 cm) = 0.19 ± 0.07 logMAR (20/31) (P = .03); and UNVA (40 cm) = 0.18 ± 0.10 logMAR (20/30) (P = .37).

CONCLUSIONS:

Effective restoration of visual acuity was demonstrated in both groups, with high levels of visual quality and patient satisfaction. Better results in near visual acuity were demonstrated in the mixed group. [J Refract Surg. 2019;35(7):408-416.].
