Implantation of a new non-diffractive extended depth-of-focus intraocular lens with minimonovision resulted in satisfying far, intermediate, and near visual acuity with a consistent reduction of spectacle dependence and improvement in patient's quality of life.
Purpose To evaluate overall patient satisfaction, spectacle independence, visual acuity, and prevalence of optical phenomena following bilateral implantation of a new non-diffractive extended depth-of-focus intraocular lens targeted for minimonovision. Methods Multicenter prospective case series. Postoperative far and near visual acuity at 3 months and patient quality of life by NEI-VFQ-25 questionnaire were assessed. Postoperative evaluation included defocus curves analysis, spectacle independence assessment, and recording of photic phenomena. Results The study enrolled 97 eyes of 59 patients that underwent femtosecond-assisted cataract surgery with AcrySof IQ Vivity intraocular lens implantation. Thirty subjects (60 eyes) were eligible for analysis. After 3 months, postoperative achieved binocular uncorrected visual acuity was -0.03 +/- 0.06 logarithm of the minimum angle of resolution for distance, 0.06 +/- 0.06 logarithm of the minimum angle of resolution for intermediate, and 0.19 +/- 0.03 logarithm of the minimum angle of resolution for near. Defocus curve showed a smooth profile with no abrupt decrease of visual acuity. Minimonovision significantly improved visual acuity compared to when minimonovision was neutralized, for values of defocus curves from -1 to -3 D (p < 0.05). Twenty-six (87%) patients reported complete spectacle independence. High levels of satisfaction for distance and near vision resulted at VFQ-25 questionnaire. Only two patients complained of halos (6.7%) and one of them also of glare (3.3%). Conclusions Implantation of this new non-diffractive extended depth-of-focus intraocular lens with minimonovision resulted in satisfying far, intermediate, and near visual acuity with a consistent reduction of spectacle dependence and improvement in patient's quality of life.
