Toric Intraocular Lens Implantation in Pediatric Cataract

TILIPC
Start date: March 1, 2024
Phase: N/A
Study type: Interventional

To evaluate the visual and refractive outcomes after an intraocular lens (IOL) implantation in pediatric eyes with cataract and preexisting corneal astigmatism

NCT ID: NCT06016231 Enrolling by invitation - IOL Clinical Trials

Clinical Outcomes of Patients With a Light Adjustable Lens (LAL) in at Least One Eye

Start date: August 15, 2023
Phase:
Study type: Observational

Patient Preference and Visual Quality With Contralateral Synergy Versus Panoptix

Start date: April 12, 2022
Phase:
Study type: Observational

The goal of this study is to compare the visual quality and patient preference of the Synergy IOL versus the PanOptix IOL when one of each lens is placed in the same patient.

Visual Outcomes With a Trifocal IOL in Subjects With Open-angle Glaucoma

Start date: February 1, 2021
Phase: N/A
Study type: Interventional

NCT ID: NCT04387721 Recruiting - Astigmatism Clinical Trials

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

Start date: July 29, 2019
Phase:
Study type: Observational

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.

NCT ID: NCT04130490 Completed - Cataract Clinical Trials

The Heidelberg Engineering ANTERION Anterior Segment Cornea and IOL Precision and Agreement Study

Start date: October 11, 2019
Phase:
Study type: Observational

NCT ID: NCT03371576 Completed - Cataract Clinical Trials

Clinical Analysis of Two Toric Intraocular Lenses

Start date: June 1, 2012
Phase: N/A
Study type: Observational

Purpose: Comparison of two torical intraocular lenses with differents haptic design in patients with cataract. Methods: In this prospective, randomized clinical trial 120 eyes of 60 patients underwent phacoemulsification. In patient's eyes the Tecnis torical IOL (Abbott Medical Optics) or the AT Torbi torical 709 MB IOL (Zeiss Medical AG) were randomly implanted. Three months after surgery visual acuity, rotation stability and astigmatism correction were evaluated.
