Long-Term Optical Stability And Patient Satisfaction Three Years After Bilateral Edof Iol Implantation

To evaluate long-term visual performance and patient-reported outcomes three years after bilateral implantation of an extended depth of focus (EDOF) intraocular lens (Extend, Hanita Lenses, Israel).

This ambispective, non-randomized, non-comparative, single-center case series included patients who underwent bilateral cataract surgery with implantation of the Extend EDOF IOL at least three years prior to evaluation. All eyes were originally targeted for emmetropia. At follow-up, patients underwent manifest refraction, slit-lamp examination with specific assessment of posterior capsule transparency, fundus evaluation, and binocular defocus curve testing. Patient-reported outcomes were assessed using the VF-14 questionnaire and a structured dysphotopsia and spectacle-independence survey.

Sixty-one patients (122 eyes) were evaluated ≥3 years postoperatively. Mean spherical equivalent was −0.01 ± 0.29 D, indicating refractive stability. The binocular defocus curve showed 0.0 logMAR at plano and maintained ≤0.2 logMAR from plano to −2.00 D, with a smooth continuous profile and no secondary peak. No posterior capsule opacification or other long-term complications were observed. Mean VF-14 score was 98.7 ± 2.7, with 75% scoring 100. Spectacle independence was 100% for distance, 96.7% for intermediate, and 80.3% for near. Mild halos or glare occurred in <5%, with no moderate or severe dysphotopsia.

Three years after bilateral implantation, the Extend EDOF IOL showed stable refractive outcomes, sustained functional range of vision, high spectacle independence, and minimal dysphotopsia, supporting its long-term optical stability and consistent patient satisfaction in real-world practice.
