Visual Outcome Measures With Diffractive And Refractive Extended Depth Of Focus (Edof) Intraocular Lenses.

The aim of this study is to evaluate spectacle independence for far, intermediate, and near vision, as well as patient satisfaction following implantation of two models of Extended Depth of Focus intraocular lenses (EDOF-IOLs).

This two-center study includes data from patients who underwent cataract surgery performed by ten experienced surgeons from January 2024. Patients received either a diffractive EDOF-IOL (AT LARA, Carl Zeiss, Germany) or a refractive EDOF-IOL (Visiotis Progress +, IOL Expert, Germany) at the surgeon’s discretion, aiming for emmetropia.

The study consists of two cohorts:

• Retrospective cohort: Visiotis Progress (n=185), AT LARA (n=101)
• Prospective cohort: Visiotis Progress (n=30), AT LARA (n=30)

Visual outcomes were assessed one month postoperatively, measuring uncorrected distance visual acuity (6 m), intermediate visual acuity (80 cm), and near visual acuity (40 cm). Patient satisfaction, including spectacle dependence, glare, and halos, was also evaluated.

Both EDOF-IOL models provided a high level of spectacle independence for distance and intermediate vision, allowing most patients to perform daily activities without glasses, except for near-vision tasks such as reading. Overall, patient satisfaction was high, with minimal reports of glare or halos.

Both diffractive and refractive EDOF-IOLs offer excellent spectacle independence for distance and intermediate vision, with high patient satisfaction. However, near-vision correction may still be required for certain tasks. Further follow-up is needed to assess long-term outcomes.
