This study compared the clinical outcomes and optical characteristics of the TECNIS Eyhance (EH; Johnson & Johnson Vision, Santa Ana, CA, USA) enhanced monofocal and the TECNIS PureSee (PS; Johnson & Johnson Vision) non-diffractive extended-depth-of-focus intraocular lenses (IOLs) sharing the same platform. In this retrospective analysis of real-world data, 69 eyes from 49 patients (EH: 35 eyes; PS: 34 eyes) were evaluated for visual acuity (VA) at distance, intermediate, and near ranges, alongside monocular defocus curves at 3-months postoperatively. To ensure a fair comparison and optimize intermediate vision, a consistent postoperative target refraction of -0.20 to -0.30 D was set for all eyes. Generalized estimating equations accounted for intra-subject correlations. At 3-months, both IOLs provided comparable excellent distance vision and refractive predictability without significant intergroup differences in prediction error (p = .846) or mean absolute error (p = .833). However, the PS IOL delivered significantly better uncorrected intermediate (0.16 vs. 0.23 logMAR; p < .001) and near VA (0.32 vs. 0.40 logMAR; p < .001) than the EH IOL. In conclusion, while both IOLs offer excellent distance vision and refractive stability, the non-diffractive PS IOL provides superior intermediate and near visual performance compared to the EH IOL.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
