Retrospective analysis on the visual outcomes and photic phenomena following bilateral extended depth of focus intraocular lens implants.

OBJECTIVE To evaluate binocular visual outcomes and presence of photic phenomena in patients with bilateral extended depth of focus (EDF) intraocular lens (IOL) implants. DESIGN Retrospective consecutive case series. PARTICIPANTS Patients above the age of 18 years without prior ocular pathology or surgery with bilateral EDF IOL implants (ZXR00; Johnson & Johnson Vision) between January 2015 and December 2017 in Canadian ophthalmology centres. METHODS Patient charts were retrospectively evaluated for binocular uncorrected distance visual acuity (UCDVA), binocular corrected distance visual acuity (CDVA), binocular uncorrected near visual acuity (UCNVA), photic phenomena (glare, halos, or dysphotopsia), complications, or reoperations. Subgroup analysis investigated the effect of monovision on the above outcomes. RESULTS In total, 87 individuals with bilateral EDF IOL implants were included in the analysis. Median logMAR pre-operative CDVA was 0.18 (0.1-0.3). The median logMAR postoperative bilateral UCDVA was 0.14 (0.00-0.18), median CDVA was 0.00 (0.00-0.10), and median UCNVA was 0.10 (0.10-0.20). Overall, 16 (18.4%) cases self-reported the presence of photic phenomena, the most common of which were halos (13.8%). Subgroup analysis determined that there was no significant difference in visual outcomes or presence of photic phenomena when stratifying patients based on the degree of postoperative monovision (p = 0.31-0.57). CONCLUSIONS Overall, the Tecnis Symfony EDF IOL provided a reasonable range of binocular distance and near vision. Approximately 12.6% of patients self-reported any postoperative photic phenomena; however, all cases were subjectively considered mild and tolerable. Monovision had no effect on visual outcomes or the presence of photic phenomena.
