To evaluate the clinical outcomes of cataract surgery using novel diffractive trifocal intraocular lenses(IOLs) in Koreans. Methods: This was a retrospective, consecutive, interventional study of cataract surgery using POD FineVisionIOL implantation. Complete ophthalmologic examinations were performed preoperatively and postoperatively. Defocus curves were assessed over a range of +1.5 to -4.0 diopters in 0.5-diopter steps at one month postoperatively. Uncorrected distant visual acuity, uncorrected intermediate visual acuity, uncorrected near visual acuity,corrected distant visual acuity, distant-corrected intermediate visual acuity, and distant-corrected near visual acuitywere assessed one month postoperatively, and manifest refraction was performed during every visit. Results: The study analyzed 31 eyes in 20 patients. There were statistically significant improvements in uncorrecteddistance visual acuity, uncorrected intermediate visual acuity, uncorrected near visual acuity, corrected distancevisual acuity, distance-corrected intermediate visual acuity, and distance-corrected near visual acuity (p <0.001). The final postoperative refractive outcomes showed statistically significant myopic shifts compared to thetarget refraction based on SRK/T, SRK-II, Haigis, and Hoffer Q formulas (p < 0.001). Conclusions: POD FineVision IOLs provide stable visual restoration with improvements of near and intermediatevision in presbyopic eyes. POD FineVision IOLs show myopic shift in
