Abstract

PURPOSE: To evaluate visual outcomes, spectacle independence, and optical phenomena after bilateral implantation of a nondiffractive extended depth-of-focus (EDoF) intraocular lens (IOL) targeted for minimonovision.

SETTING: University Eye Clinic Maastricht, the Netherlands.

DESIGN: Prospective case series.

METHODS: Patients with age-related cataract were bilaterally implanted with a nondiffractive EDoF IOL (Alcon AcrySof IQ Vivity), targeted for minimonovision. Outcome measures were the uncorrected distance visual acuity (UDVA), corrected distance visual acuity, uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), distance corrected intermediate visual acuity, distance corrected near visual acuity, refractive outcomes, defocus curves, spectacle independence, photic phenomena, and Catquest-9SF questionnaire.

RESULTS: 44 eyes of 22 patients were included. The mean binocular UDVA, UIVA, and UNVA were -0.07 (±0.10), 0.04 (±0.09), and 0.23 (±0.12) logMAR, respectively. The percentage of eyes within ±1.0 diopters (D) and ±0.5 D of target was 100% and 95% for the dominant eye and 100% and 86% for the nondominant eye, respectively. The binocular defocus curve was better than 0.10 logMAR over a range from -2.0 D to +0.5 D. The percentage of patients who reported not or rarely using spectacles for distance, intermediate, and near viewing distance was 96%, 68%, and 38%, respectively. The percentage of patients who experienced no halos, glare, or starbursts were 91%, 91%, and 100%, respectively. The Catquest-9SF showed a high patient satisfaction for daily life activities.

CONCLUSIONS: Bilateral AcrySof IQ Vivity IOL implantation targeted for minimonovision provided good visual acuity results for far and intermediate with functional near vision, high level of patient satisfaction and spectacle independence, and a monofocal disturbance profile.
