NCT ID: NCT05431868 Completed - Cataract Clinical Trials

Objective and Subjective Outcomes of a Trifocal IOL in Eyes With Different AL

Start date: January 1, 2019
Study type: Observational

This prospective cohort study enrolled patients with implantation of a trifocal IOL. Only one eye of each patient was enrolled. Eyes were devided into three groups according the axial length (AL), including the short AL group, the control group and the long AL group. Manifest refraction, uncorrected and distance-corrected visual acuity at different distances, contrast sensitivity, aberrations and IOL decentration were measured three months after surgery. Spectacle independence, adverse photic phenomena, overall satisfaction and life quality were assessed with a questionnaire.

NCT ID: NCT05427526 Enrolling by invitation - Cataract Clinical Trials

Outcome of Zeiss AT LARA EDOF Lens Implantation in Vitrectomized Eyes

Start date: February 14, 2022
Phase: N/A
Study type: Interventional

To determine the surgical outcome and patient satisfaction in patients who underwent AT LARA lens implantation during or after vitrectomy at a relatively young age (around 55 years of age), mostly to treat (urgent) retinal detachment.

NCT ID: NCT05417633 Recruiting - Presbyopia Clinical Trials

RayOne EMV Mini-monovision - Efficiency and Safety of 3 Grades of Mini-monovision

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Aim:To determine the effectiveness and subjective satisfaction of patients with bilateral cataract surgery and implantation of intraocular lens (IOL) RayOne EMV with enhanced optic, using different degrees of mini-monovision (up to 0.74, between 0.75 -1.24 and 1.25-1.75). To compare individual groups between themselves . In particular, we would like to compare the independence of spectacle correction when looking into the distance, at medium distance and at reading distance.

NCT ID: NCT05416177 Not yet recruiting - Cataract Clinical Trials

Assessment of Vivity With French Clinical Data Related to the Toric Model Study

Start date: August 1, 2022
Study type: Observational [Patient Registry]

Presbyopia-correcting implant (PC-IOL): AcrySof IQ Vivity (Alcon) has been evaluated in 2 large pivotal trials (US and OUS trials). These tests showed that this PC-IOL restored intermediate visual acuity (IVA) and near visual acuity (NV A) superior to that of the reference monofocal AcrySof implant. In these tests, it was demonstrated that distance visual acuity (DVA) was non-inferior. However, the intermediate visual acuity for this implant in its toric version has not been evaluated.

NCT ID: NCT05414773 Not yet recruiting - Cataract Clinical Trials

Zeiss® IOLMaster 700 Corneal Topography Module Comparison With Schwind's Sirius Corneal Topography®

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

In order to determine the intraocular lens to be implanted during cataract surgery, keratometry and axial length must be measured in preoperative. The axial length is obtained by ocular ultrasound mode B. Keratometry is obtained by means of an automatic refractometer or corneal topography. Currently, ultrasound scanners are being developed with a topography module to combine axial length and keratometry measurement. The investigators want to evaluate the corneal topography module of the Zeiss® IOL Master 700 biometer.

NCT ID: NCT05413330 Completed - Cataract Clinical Trials

Corticosteroid Injection Combined With Cataract Surgery in Diabetic Eyes.

Start date: September 12, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

We aim in this study to investigate the effect of intravitreal triamcinolone acetonide injection on the development of macular edema and the progression of diabetic retinopathy. Whether this injection hastens cataract surgery results or not. We will categorize the participants into two groups: the case group who will receive the injection at the end of surgery, and the control group who will have routine cataract surgery with no extra injections.

NCT ID: NCT05411341 Not yet recruiting - Cataract Clinical Trials

Comparison of Two Different Optical Biometric Systems

Start date: June 2022
Study type: Observational [Patient Registry]

Primary objective of this study is to evaluate and compare the measurements of two different optical biometrics systems in patients who will undergo cataract surgery or presbyopia surgery using intraocular lenses (IOL-PC).

NCT ID: NCT05401760 Not yet recruiting - Pediatric Glaucoma Clinical Trials

Combined Phacoaspiration and Angle Surgery Versus Phacoaspiration in Pediatric Cataract

Start date: May 30, 2022
Phase: N/A
Study type: Interventional

The aim of this study is to report the effectiveness of phacoaspiration when combined with angle surgery in preventing postoperative glaucoma following pediatric cataract surgery

NCT ID: NCT05396599 Not yet recruiting - Cataract Clinical Trials

A Clinical Study Comparing Postoperative Outcomes Between the TECNIS Intraocular Lens.

Start date: June 30, 2022
Phase: N/A
Study type: Interventional

This is a prospective, multi-center, masked, three-arm, randomized clinical study of the TECNIS Eyhance Toric II IOL (test #1) and TECNIS Synergy Toric II (test #2) compared to the TECNIS Toric 1-Piece IOL (control).

NCT ID: NCT05396547 Not yet recruiting - Cataract in Old Age Clinical Trials

Study On The Performance And Safety Of The LEDINBIO CE Device On Visual Acuity In Subjects With Cataract

Start date: June 2022
Phase: N/A
Study type: Interventional

Single arm, unmasked study to evaluate the performance and safety of the LEDINBIO CE Device for the non-invasive treatment of vision loss in age-related cataract.
