Nondiffractive presbyopia-correcting IOL improves near and distance vision with stable distance
A novel nondiffractive presbyopia-correcting IOL improves intermediate and near vision quality while maintaining good distance vision and a low rate of visual disturbances, according to data from AAO 2020 Virtual.
Researchers evaluated uncorrected visual acuity (UCVA) after bilateral implantation of the nondiffractive IOL (DFT015; AcrySof IQ Vivity, Alcon) versus an aspheric monofocal IOL (SN60WF; AcrySof IQ, Alcon). For the study, 220 patients in 11 US sites were bilaterally implanted with DFT015 (n = 106) or SN60WF (n = 111). Photopic uncorrected distance (UCDVA), intermediate, and near visual acuities (UCIVA/ UCNVA), and manifest refraction spherical equivalent (MRSE) were measured at 6 months. Uncorrected quality of vision and visual disturbances were assessed with validated questionnaires, the IOL Satisfaction Questionnaire (IOLSAT) and the Questionnaire for Visual Disturbances (QUVID).
Ninety-two percent and 87% of first eyes achieved absolute MRSE ≤0.5 D for DFT015 and SN60WF, respectively. Mean binocular between-group differences <1 line for UCDVA, ~1-line improvement for UCIVA, and >1-line improvement for UCNVA. Ninety-four percent, 92% and 57% reported good vision without spectacles at distance, intermediate, and near with DFT015, versus 90%, 63% and 25% with SN60WF. Patient-reported visual disturbances were similar between the groups, with <2% in each group reported very bothersome starbursts, halos, and glare at 1 and 6 months.
