The tested IOLs were: TECNIS ZMB00 (bifocal; Abbott Medical Optics, Abbott Park, IL), TECNIS Symfony ZXR00 (extended depth of focus; Abbott Medical Optics), and FineVision GFree hydrophobic (trifocal; PhysIOL, Liège, Belgium). Their surface topography was analyzed by optical microscopy. Modulation transfer function (MTF) and spherical aberrations were determined on optical bench for variable pupil apertures and with two cornea models (0 µm and +0.28 µm). United States Air Force target imaging was analyzed for different focal points (near, intermediate, and far). Point spread function (PSF) and halos were quantified and compared.

The following IOLs were analyzed: a monofocal AcrySof, a bifocal AcrySof IQ Restor SN6AD1, a trifocal AcrySof IQ PanOptix TFNT00 (all three lenses from Alcon, Fort Worth, USA), and an extended-depth-of-focus (EDOF) TECNIS® Symfony ZXR00 (Abbott Medical Optics, Santa Ana, USA). Table 1 summarizes the key characteristics of the studied lenses.
The aspheric AcrySof IQ Restor SN6AD1 has a refractive base dedicated to refracting incident light rays to far focus and a diffractive grating that creates a secondary (near) focus. The diffractive design features apodization that further amplifies distance vision with increasing pupil size by decreasing the diffractive step-height towards the periphery.
The AcrySof IQ PanOptix TFNT00 features a central refractive-diffractive area of 4.5 mm in diameter that is encircled by a refractive ring in the periphery. According to the manufacturer, the diffractive zone incorporates a quadrifocal optic with three unsequential diffraction orders distributing light rays to far, intermediate, and near foci, while the fourth-order further reinforces far vision.
The TECNIS® Symfony ZXR00 is based on a proprietary echelette design with a diffractive-refractive surface that is intended not only to generate the EDOF but also to counteract the chromatic aberration and thereby improve contrast sensitivity.
All studied lenses share an equal base power of +21.0 D.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
