Visual performance following implantation of presbyopia correcting intraocular lenses

Objective To compare the visual outcomes following bilateral implantation of 3 presbyopia correcting IOLs. Methods Results are reported for patients who underwent phacoemulsification with bilateral implantation of one of the following IOLs: Panoptix IOL, AT LISA tri IOL and Symphony IOL. Six months postoperative examination included monocular UIVA at 80 and 60 cm and monocular UNVA and DCNVA at 40 cm, monocular UDVA and CDVA, Spherical equivalent (SE) refraction, binocular defocus curve, contrast sensitivity, photopic phenomena, and spectacle independence. Results UIVA at 80 cm was significantly better in the AT LISA group and the Symfony groups than the Panoptix group, while UIVA at 60 cm was better in the Symfony group and the Panoptix group than the AT LISA group. A worse DCNVA was recorded in the Symfony group. At a defocus of -2.50 D, the near VA was similar in the PanOptix and AT LISA groups (0.05, 0.07 logMAR respectively), which were significantly better than the Symfony group (0.3 LogMAR). Binocular photopic and scotopic contrast sensitivity outcomes were similar among the three groups at all spatial frequencies. In Symphony group, the frequency and the degree of bother of photic phenomena was relatively higher than the other two groups. Higher percentage of patients in symphony group reported their need for reading glasses. Conclusion PanOptix IOL and AT LISA IOL would be a good choice for patients aiming for an optimum near vision, while Symfony IOL seems suitable for patients having the priority for good intermediate vision.
