Visual Outcomes, Patient Satisfaction, and Light Distortion Analysis After Blended Implantation of Rotationally...

To evaluate the visual outcomes and patient satisfaction after blended implantation of rotationally asymmetric multifocal intraocular lenses (IOLs) (LENTIS Mplus LS-313 +3.00 and +1.50 diopters [D], Oculentis GmbH).

This was an interventional prospective study that included 40 eyes of 20 patients who underwent uneventful refractive lens exchange. Patients were implanted with the LENTIS Mplus LS-313 +3.00 D IOL in the non-dominant eye and the +1.50 D IOL in the dominant eye. Twelve months after surgery, binocular and monocular uncorrected and corrected near, intermediate, and distance visual acuity, defocus curve, contrast sensitivity, and light distortion analysis (LDA) were evaluated. Monocular total ocular aberrometry with a pyramidal wavefront sensor (Osiris; CSO) and patient satisfaction was evaluated with the 10-item Near Activity Vision Questionnaire (NAVQ-10).

There was a statistically significant improvement in the uncorrected distance visual acuity in both eyes after surgery (P < .001), with good uncorrected near and intermediate distance visual acuity (0.18 and 0.38 logMAR, respectively). The binocular defocus curve showed good levels of visual acuity for the most important ranges of vision. Contrast sensitivity and LDA had significantly better results when measured binocularly than monocularly. Higher order aberrations were significantly higher in the +3.00 D eye (P < .001). The mean Rasch score for the NAVQ-10 questionnaire was 26.9 ± 27.66.

Visual outcomes, defocus curve, LDA, and contrast sensitivity were significantly better binocularly than monocularly. The implantation of a blended IOL combination with different near addition complements the advantages of each IOL, improving binocular visual outcomes and providing good patient satisfaction.
