Performance of Extended Depth of Focus Intraocular Lens in Eyes with Preexisting Retinal Disease.

Abstract

Introduction: Extended depth of focus (EDOF) intraocular lens (IOL) offers improved near and intermediate vision, aiming to reduce spectacle dependence in cataract patients. This research aimed to evaluate the performance of EDOF IOL in patients with retinal pathologies following cataract surgery.

Methods: The medical charts of thirty-three eyes with retinal pathologies and 100 healthy eyes that underwent cataract extraction with implantation of an EDOF IOL and had at least 3 weeks of postoperative follow-up were retrospectively included. Patients' overall satisfaction, spectacle dependence, visual perception, and side effects were evaluated with a self-reported questionnaire.

Results: Mean uncorrected visual acuities (LogMAR) were significantly better in the healthy eyes compared with the eyes with retinal pathologies: 0.05 and 0.10, p = 0.011 (distance), 0.06 and 0.16, p = 0.001 (intermediate), and 0.20 and 0.28, p = 0.026 (near), respectively. No or rare use of spectacles for any distance was reported by 71% and 38% of patients, respectively (p = 0.004). Haloes/glare were reported by 17% and 23%, respectively (p = 0.556); only in 7% and 4% it was clinically disturbing (p > 0.999). The same IOL would be chosen again in 77% and 73% of patients, respectively, (p = 0.550).

Conclusion: Patients with retinal pathologies who were implanted with an EDOF IOL demonstrated excellent distant uncorrected visual results with reasonable intermediate and near uncorrected visual results alongside high satisfaction; however, results were inferior to those of the control healthy eyes.
