Comparison Of Near Visual Acuity Using A Non-Diffractive Extended Depth-Of-Focus Iol With Different Target Refractions

To evaluate visual performance with focus on near visual acuity of a non-diffractive extended depth-of-focus IOL (Alcon AcrySof IQ Vivity) in a mini-monovision compared to an emmetropic setting.

Department of Ophthalmology of the University Hospital Munich, Germany

In this prospective, comparative clinical study, patients aged > 45 years with bilateral cataracts or the wish for clear lens exchange surgery and astigmatism less than one diopter (D) were randomly assigned to either the group with target refraction emmetropia or the mini-monovision group with -0.75D in the non-dominant eye. Monitoring took place 1 week and 3 months after surgery on both eyes. Outcome measures involved uncorrected near (UNVA), uncorrected distance (UDVA) and corrected distance (CDVA) visual acuity (VA) as well as defocus curve and Quality of Vision questionnaire for spectacle independence and optical phenomena.

In this ongoing study we so far included 20 eyes of 10 patients in the mini-monovision group and 14 eyes of 7 patients in the emmetropia group. An improvement in UDVA in both groups was observed that was not significant between the groups (p>0.05). In the mini-monovision group a shift towards better VA at near viewing distance in comparison to the emmetropia group was seen with a VA of 0.2 vs. 0.3 logMAR at -2D (mini-monovision vs. emmetropia respectively). The percentage of patients who postoperatively reported not using spectacles for reading distance was 83% for the mini-monovision and 57% for the emmetropia group. Overall results will be presented at the congress.

Bilateral implantation of the AcrySof IQ Vivity IOL showed good visual performance with an advantage in a mini-monovision setting for functional near vision.
