Abstract

Purpose
To evaluate the clinical outcomes of a non-diffractive extended-depth-of-focus (EDoF) intraocular lens in eyes by epiretinal membrane (ERM) stage.
Methods
Clinical records of 289 eyes with AcrySof® IQ Vivity TM (Alcon Laboratories) implantation were reviewed. Eyes were grouped according to ERM stage as no ERM (n = 228), stage 1 (n = 29), stage 2 (n = 20), and stage 3 (n = 12) ERM. Corrected and uncorrected distant visual acuity (CDVA and UDVA, respectively), uncorrected intermediate and near visual acuity (UIVA and UNVA), contrast sensitivity detected by the area under the log contrast sensitivity function (AULCSF), Strehl ratio, area ratio, and intraocular aberration were compared.
Results
There was no difference in UDVA, UIVA, UNVA, or CDVA between groups (p = 0.639, p = 0.871, p = 0.963, and p = 0.051, respectively). There was no significant difference in Strehl ratio (p = 0.208), area ratio at 4 mm (p = 0.434), area ratio at 5 mm (p = 0.511), or ocular aberrations (p = 0.311 for total aberration). The AULCSF showed significant differences during both day (1.48 ± 0.21, 1.41 ± 0.18, 1.33 ± 0.17, and 1.31 ± 0.19 for no ERM, stage 1, stage 2, and stage 3 ERM, respectively; p = 0.036) and night (1.21 ± 0.21, 1.22 ± 0.12, 1.02 ± 0.20, and 1.08 ± 0.10 for no ERM, stage 1, stage 2, and stage 3 ERM; p = 0.027).
Conclusions
Eyes with stage 3 ERM without outer retinal involvement may benefit from EDoF technology when there is no metamorphopsia and when accompanied by timely membrane removal.
