Functional Outcomes And Reading Performance After Implantation Of A Non-Diffractive Edof Iol Using A Mini-Monovision Approach In Femtosecond Laser Assisted Refractive Lens Exchange

Trifocal IOLs may provide excellent visual acuity at all distance, but patients may experience bothersome dysphotopsia. In this study, we aim to evaluate the functional outcomes and photic phenomena after binocular implantation of the Vivity IOL (Alcon, Fort Worth, TX, USA) using a mini-monovision approach.

University Eye Clinic Heidelberg, Germany

In this on-going clinical study, bilateral delayed sequential femtosecond laser-assisted phacoemulsification and implantation of the AcrySof or Clareon Vivity IOL with mini-monovision of -0.75 D is performed. Postoperative follow-up examination at 3-months includes uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected intermediate (DCIVA) visual acuity at 66 cm distance, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 40 cm distance. Defocus curve testing with distance-correction and reading performance evaluation were also performed at the 3-months follow-up visit.

So far, 6 eyes of 3 patients with a mean age of 57 ± 6 years have been enrolled in the study. 3-months postoperative data will be available by September 2025.

Our hypothesis is that the femtosecond laser-assisted refractive lens exchange with bilateral implantation of the Vivity IOL using a mini-monovision offers good unaided vision at far, intermediate, and near distances, with low rates of photic phenomena, presenting an alternative to trifocal IOLs.
