Detailed Description

Primary Objective

To evaluate whether the implantation of enhanced monofocal intraocular lenses during cataract surgery results in fewer adverse visual phenomena (dysphotopsias) than the implantation of extended depth-of-field (EDoF) intraocular lenses.

Secondary Objectives

To evaluate whether there are differences in best-corrected visual acuity at various distances, contrast sensitivity, visual quality, and quality of life between patients implanted with enhanced monofocal intraocular lenses and those implanted with extended depth-of-field intraocular lenses.

To evaluate whether there are differences in best-corrected visual acuity at various distances, contrast sensitivity, visual quality, and quality of life among the four enhanced monofocal intraocular lenses analyzed in the present study.

To evaluate whether there are differences in best-corrected visual acuity at various distances, contrast sensitivity, visual quality, and quality of life between the two extended depth-of-field intraocular lenses analyzed in the present study.
