Comparison of refractive and visual outcomes of 3 presbyopia-correcting intraocular lenses.

PURPOSE: To evaluate and compare the clinical outcomes after cataract surgery with implantation of 3 types of trifocal diffractive intraocular lenses (IOLs). SETTING: Hospital da Luz, Lisbon, Portugal. DESIGN: Prospective comparative case series. METHODS: Patients undergoing phacoemulsification cataract surgery with implantation of 1 of the 3 trifocal IOLs were enrolled: TECNIS Synergy (Synergy group, 30 patients), Acrysof PanOptix (PanOptix group, 30 patients), and POD F (Finevision group, 30 patients). The outcomes of distance, intermediate, and near visual acuity (VA), refraction, defocus curve, photic phenomena, and spectacle independence were evaluated at the 3-month follow-up. RESULTS: 180 eyes of 90 patients were enrolled. No statistically significant differences were found between groups in monocular distance-corrected intermediate (Synergy group 0.04 ± 0.11, PanOptix group 0.05 ± 0.09, and Finevision group 0.08 ± 0.10; P = .107) and near VA (0.01 ± 0.08, 0.01 ± 0.06, and 0.04 ± 0.10, respectively; P = .186). Similarly, no statistically significant differences among groups were found in binocular uncorrected distance (P = .572), near (P = .929), and intermediate VA (P = .327). By contrast, statistically significant differences between groups were found in the visual acuity for the vergence demands of -0.50, -1.00, -2.00, -3.50, and -4.00 diopters (P ≤ .045). No statistically significant differences among groups were found in the frequency, severity, and bothersomeness of different disturbing visual symptoms, including glare and halos (P ≥ .129). More than 87 (96%) of patients in all groups did not require the use of spectacles at any distance postoperatively. CONCLUSIONS: The 3 trifocal IOLs evaluated provided an effective visual rehabilitation with minimal incidence of photic phenomena. A trend to obtain a wider range of functional focus was observed with the TECNIS Synergy IOL.
