Visual Outcomes, Spectacle Independence And Patient-Reported Visual Symptoms Following The Implantation Of A New Enhanced Monofocal Iol With Intermediate Optimized Optics

To evaluate the visual outcomes, spectacle independence and frequency of unwanted visual symptoms following the implantation of a new enhanced monofocal IOL that uses higher-order spheric coefficients on the central part of the posterior surface to broaden the depth of focus.

Private Practice in the US.

This prospective observational study included 41 patients who underwent bilateral cataract surgery and implantation of a new enhanced monofocal (non-toric/toric) IOL (enVista Aspire, Bausch & Lomb). Patients with amblyopia, AMD, and diabetic retinopathy were excluded. However, patients with prior RK, LASIK, mild drusen or mild glaucoma were allowed to participate. Postoperative assessments included binocular uncorrected visual acuities at distance, intermediate, and near. A short survey comprising questions from the PRSIQ (patient-reported spectacle independence questionnaire) and QoV (quality of vision questionnaire) was used to assess spectacle independence and patient-reported incidence of visual symptoms at 3 weeks postoperatively.

Postoperatively, 98% of patients achieved binocular UDVA of 20/25 or better. 98% had binocluar UIVA of 20/32 or better.

90% had binocular UNVA of 20/40 or better. All (100%) enVista Aspire IOL implanted patients were spectacle-independent for distance and could perform distance tasks all of the time without wearing correction.  More than 95% of patients were spectacle-independent for intermediate vision. All patients reported that they could function comfortably ‘all the time’ (83%) or ‘most of the time’ (17%) without wearing glasses or contacts for intermediate vision.  The percentage of patients reporting no or occasional unwanted visual symptoms was 87% (halos), 91% (starbursts), and 74% (glare).

Implantation of enVista Aspire IOL provided excellent binocular visual acuities, spectacle independence at distance and intermediate. Spectacle independance at near was obtained for almost 1/2 of the patients. The frequency of visual symptoms was also low, with a high proportion of patients reporting no or occasional dysphotopsia.
