Abstract
PURPOSE: To assess the power profile and optical performance of two extended range of vision (ERV) intraocular lenses (IOLs), TECNIS® Eyhance (ICB00) and LuxSmartTM, and compare them with their monofocal counterpart lenses with similar platforms and materials: TECNIS® 1-piece (ZCB00) and LuxGoodTM, 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, we measured the power distribution and (fourth- and sixth- order) spherical aberration (SA) across the lens aperture as well as the optical performance using modulation-transfer-function-based metrics with through-focus evaluation. Three nominal powers (+10.00, +20.00, and +30.00 D) and three pupil sizes (2.0, 3.0, and 4.5 mm) were considered to assess whether the base power of the lens and the pupillary dynamics have an influence on the depth of focus extension. RESULTS: TECNIS® Eyhance and LuxSmartTM 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. LuxSmartTM 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 two ERV IOL designs are related to differences of power and SA profile. The nominal base power of the IOLs have little impact on their optical quality. However, the pupil dynamics plays a key role since it determines the effective add power and optical performance of the ERV IOLs.
