Purpose: To evaluate clinical outcomes following contralateral implantation of a diffractive extended depth of focus (EDOF) and a hybrid EDOF-multifocal intraocular lens (IOL) with a violet filter in a U.S.-based population.
Methods: In this prospective, non-comparative study, 60 eyes of 30 patients aged 40 years and older underwent bilateral cataract surgery and implantation of a DXR00V IOL (Tecnis Symfony OptiBlue) in the dominant eye and a DFR00V (Tecnis Synergy) IOL in the non-dominant eye. Outcome measures included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, distance-corrected intermediate (DCIVA, 66 cm), near and very near visual acuity (DCNVA, 40 and 33 cm), and patient-reported outcomes.
Results: At 6 months postoperatively, binocular mean UDVA and CDVA were -0.10 ± 0.07 and -0.11 ± 0.05 logarithm of the minimum angle of resolution (logMAR), respectively. The mean DCIVA was 0.26 ± 0.08 logMAR in the DXR00V eyes and 0.23 ± 0.06 logMAR in the DFR00V eyes. The mean DCNVA at 40 and 33 cm were 0.28 ± 0.12 and 0.30 ± 0.15 logMAR, respectively, in the DXR00V eyes and 0.07 ± 0.08 and 0.07 ± 0.10 logMAR, respectively, in the DFR00V eyes. The mean binocular DCIVA and DCNVA at 33 and 40 cm were 0.18 ± 0.05, 0.06 ± 0.08, and 0.06 ± 0.07 logMAR, respectively. The percentages of patients achieving spectacle independence at far, intermediate, and near distances were 100%, 100%, and 81%, respectively.
Conclusions: Contralateral implantation of the diffractive EDOF and a hybrid EDOF-multifocal IOL yielded excellent binocular visual acuity at all distances, as well as high patient satisfaction and functional performance on visual tasks. [J Refract Surg. 2024;40(10):e699-e705.].
