Abstract: Aim: To evaluate the performance of a new Extended Depth Of Focus (EDOF) Evolux Intraocular Lenses (IOLs), an extended monofocal IOL with a non-diffractive profile designed to improve intermediate vision while providing distance vision comparable to monofocal IOLs, in terms of Visual Acuity (VA) at various distances and contrast sensitivity . Materials and methods: Twenty five patients (50 eyes) were included in this retrospective case series. Every patient underwent bilateral implantation of Evolux IOLs after cataract surgery. Preoperative and postoperative parameters evaluated included axial length, IOL power, refractive error in terms of spherical equivalent (SE) and VA for various distances. Patients were reviewed periodically after surgery. At 1 month after surgery, Contrast Sensitivity (CS) was assessed. Results: The study included 14 (56%) male and 11 (44%) female patients. Significant improvement in VA was observed at all distances. When assessing uniocular VA, near VA > N8 was seen in 80% of eyes, intermediate VA > 6/9 was seen in 54% eyes and distance VA > 6/6 was seen in 96% eyes. Binocular VA at 1 month showed 92% of patients with near vision comparable to N8 or better and 96% with distance vision of 6/6 or better. The mean CS was 0.07 ± 0.02. At 1 month, the mean SE was -0.33 ± 0.46 Conclusion: This study shows that extended mono focal Evolux iols with non-diffractive optical profile safe, effective and stable providing excellent distance vision, intermediate vision and better near vision compared to standard monofocal IOLs.
