Abstract Body:
Purpose: To evaluate the visual acuity outcomes and the presence of photic phenomena related to the Tecnis Symfony Extended Depth of Focus (EDF) Intraocular Lens (IOL).
Study Design: Retrospective Chart Review
Methods: All consecutive cases performed by 3 surgeons in a single center were retrospectively evaluated within one month of surgery. Unilateral cases (EDF-IOL in one eye, monofocal aspheric IOL in the other eye), and bilateral cases (EDF-IOL in both eyes) were analyzed separately. Cases with confounding medical history or lack of follow-up data were excluded. Outcomes included Uncorrected Distance Visual Acuity (UCDVA), Corrected Distance Visual Acuity (CDVA), Uncorrected Near Visual Acuity (UCNVA), mean absolute error (MAE), photic phenomena (glare, haloes, dysphotopsia), and complications or re-operations.
Results: 254 cases were evaluated. 139 (54.7%) were unilateral, 99 (39.0%) were bilateral, and 16 (6.3%) were excluded. Median pre-operative Spherical Equivalent (SE) was +0.50 (IQR: -2.00 to +1.75). Median pre-operative CDVA was 0.18 (IQR: 0.1 to 0.3). Unilateral cases had a median UCDVA of 0.3 logMAR (IQR: 0.18 to 0.4). Bilateral cases had a median UCDVA of 0.18 logMAR (IQR: 0.1 to 0.3). For both unilateral and bilateral cases, median CDVA was 0.1 logMAR (IQR: 0 to 0.18) and median UCNVA was 0.18 (IQR: 0.1 to 0.2). Across all eyes, the MAE was 0.33 ± 0.29 diopters. 64.5% of eyes were within 0.25 diopters of the target refraction. Overall, 32 (13.4%) cases reported moderate to severe photic phenomena (non-directed), the most common being haloes (10.5%). There were no intra-operative complications. 7 (2.9%) patients underwent post-operative photorefractive keratectomy, 2 (0.8%) had an IOL explanation, and 1 (0.4%) needed IOL repositioning.
Conclusions: Overall, the extended depth of focus intraocular lens provided a reasonable range of vision for uncorrected distance and near vision. Patients with bilateral EDF IOL implantation had better UCDVA compared to unilateral implantation, while uncorrected near vision was similar. Approximately one in ten patients self-reported significant post-operative photic phenomena in the early postoperative period.
