Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary objective of this study is to compare two presbyopia correction surgical techniques, specificaly premium monovision, in which the dominant eye is corrected with an extended depth of field intraocular lens and the non-dominant eye with a trifocal diffractive intraocular lens, and the bilateral implantation of trifocal diffractive intraocular lenses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Two study groups will be formed. The first group will include patients who undergone premium monovision and the second will include patients who undergone bilateral implantation of trifocal diffractive intraocular lenses. Patients who have undergone one of the aforementioned categories of presbyopia correction surgery will be selected in order to compare the effectiveness of these techniques by evaluating uncorrected near, intermediate and distant visual acuity, uncorrected Critical Print Size (CPS) in near and intermediate distance, dysphotopic phenomena (glare, halos) through a 4-level severity scale by patients, contrast sensitivity, the need of use glasses for all distances or separately for activities requiring near or distant vision as well as the degree of subjective satisfaction of patient via interview (NEI-VFQ 25). The purpose of measuring these parameters is to calculate, through a mathematical model, the relative effectiveness of each method.
