Influence of Residual Astigmatism on Visual Acuity in Patients Undergoing Cataract Surgery With Trifocal Intraocular Lens Implantation

Astigmatism Clinical Trial

Official title:
Influence of Residual Astigmatism on Visual Acuity in Patients Undergoing Cataract Surgery With Trifocal Intraocular Lens Implantation

Clinical Trial Summary

MAIN OBJECTIVE: To assess the influence of residual astigmatism on visual acuity in the different lens foci in patients operated on for cataracts with a trifocal intraocular lens implant.

SECONDARY OBJECTIVE: To study the influence of residual astigmatism on the visual quality of the patient in the far focus and to determine if there are differences of affectation in the two study groups.

Clinical Trial Description

It will be studied how small residual astigmatisms after cataract surgery degrade the visual acuity of patients in the three focal planes of trifocal IOLs. Not only VA will be studied, but also visual quality through contrast sensitivity curves. ;
