This study assessed the refractive outcomes, optical performance, and quality of vision in patients implanted with the Intensity Hanita diffractive intraocular lens (IOL). The prospective, observational study included 64 eyes that underwent bilateral cataract surgery with Intensity IOL implantation, with evaluations conducted at 6 months post-surgery. Results indicated that 66% of eyes achieved uncorrected distance visual acuity (UDVA) of 0.10 logMAR or better. The defocus curve showed optimal vision at distance (0.02 ± 0.07 logMAR at 0.0 D) with stable performance through intermediate and near vision ranges (0.11 ± 0.08 logMAR at -1.5 D, 0.12 ± 0.12 logMAR at -2.5 D). Contrast sensitivity remained stable (p ≥ 0.06), and high-order aberrations were low, with a Strehl ratio of 0.12 ± 0.04. Mild halos and glare were reported but did not interfere significantly with daily activities, and the near activity visual questionnaire (NAVQ) indicated high patient satisfaction with near-vision tasks. These findings support the Intensity Hanita IOL’s effectiveness in providing clear vision across all distances through a five-foci distribution design that enhances depth of focus.
