Submitted: January 25, 2024 | Final revision submitted: July 6, 2024 | Accepted: July 10, 2024Purpose: To assess the power profile and optical performance of 2 extended range-of-vision (ERV) intraocular lenses (IOLs), TECNIS Eyhance (ICB00) and LuxSmart, and compare them with their monofocal counterpart lenses with similar platforms and materials: TECNIS 1-piece (ZCB00) and LuxGood, respectively. Setting: Optics and Optometry Faculties of Complutense University (Madrid) and Universitat Politècnica de Catalunya BarcelonaTech (Terrassa) in Spain. Design: Laboratory investigation on optical bench. Methods: For each design, the power distribution and (fourth and sixth-order) spherical aberration (SA) across the lens aperture were measured as well as the optical performance using modulation transfer function–based metrics with through-focus evaluation. 3 nominal powers (+10.00 diopters [D], +20.00 D, and +30.00 D) and 3 pupil sizes (2.0 mm, 3.0 mm, and 4.5 mm) were considered to assess whether the base power of the lens and pupillary dynamics have an influence on the depth-of-focus extension. Results: TECNIS Eyhance and LuxSmart IOLs had different power and SA profiles, but both designs shared a positive add power in their central region in comparison with their monofocal counterparts. LuxSmart had a greater add power while TECNIS Eyhance showed higher peak optical quality but smaller depth of focus. Conclusions: Differences of focus extension between the 2 ERV IOL designs are related to differences of power and SA profile. The nominal base power of the IOLs has little effect on their optical quality. However, pupil dynamics plays a key role since it determines the effective add power and optical performance of the ERV IOLs.engjournal article1873-4502https://doi.org/10.1097/j.jcrs.000000000000152839025665https://journals.lww.com/jcrs/fulltext/2024/10000/power_profile_and_optical_performance_of_two.13.aspxembargoed access617.7-089.243681.73617.75Intracular lensMonofocal advancedMultifocalPresbyopiaEDOFÓptica y optometríaÓptica oftálmica3311.09 Lentes2209.15 Optometría2209 Óptica
