In Vitro Aberrometric Assessment of a Multifocal Intraocular Lens and Two Extended Depth of Focus IOLs

Table 1

Zernike coefficients and standard deviation (±SD) in microns obtained for the three IOLs and for each exit pupil size (MW: Mini WELL; MP: Mplus; SYM: TECNIS Symfony ZXR00). The last row shows the HOAs.
