Choice of EDOF according to individual patients spherical aberration values

Here is a quick guide to the choice of EDOF or enhanced monofocal IOL according to the individual spherical aberration values. You see, all EDOF IOLs induce some amount of spherical aberration regardless of the optic design incorporated. It is important to see the individual spherical aberration values of the patient and then choose the particular EDOF. For example, a cornea with very high negative spherical aberration may not be ideal to be implanted with an EDOF IOL that induces more negative spherical aberration. Here is a chart that may help:

Choice of EDOF IOLs should be made according to the individual corneal spherical aberration values. For this, the above table may help in understanding the individual EDOF IOL induced spherical aberration value quickguide.org
