Bilateral Monofocal Versus Monofocal-EDOF IOL Implantation: Quality of Vision Comparison

The goal of this clinical trial is to compare visual quality after cataract surgery between two groups: bilateral monofocal intraocular lenses (IOL) and monofocal and contralateral extended depth-of-focus (EDOF) IOL implantation. The main question it aims to answer is:

• does the combination of both monofocal and EDOF IOLs presents an advantage over bilateral monofocal IOL implantation in the daily life of patients undergoing cataract surgery without the disadvantages of bilateral EDOF IOL implantation?

Participants will:

* be randomised in either bilateral monofocal group or monofocal and EDOF group * undergo visual acuity testing with and without correction at all distances * be asked to complete a quality of vision questionnaire * undergo non-invasive examinations to measure residual astigmatism, contrast sensitivity, straylight, optical aberrations, reading spead.
