NCT ID: NCT05055076 Completed - Cataract Clinical Trials

PMCF Retrospective Study Outcomes of a Monofocal Toric Intraocular Lens

Start date: August 1, 2021
Phase:
Study type: Observational

This is a monocentric retrospective, open-label clinical study in patients after unilateral or bilateral implantation of hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC and executed only with standard of care examinations. The investigational device is CE approved. The investigational device and all study products, including the devices used for the study examinations, have been used within the intended use specifications from the manufacturer. In addition, there were no invasive or other burdening examinations. The investigator is an accredited and experienced cataract surgeon and researcher. The primary endpoint is to determine rotational stability in a minimum of 120 eyes of patients with PODEYE TORIC IOL implantation after cataract surgery. Patients will be enrolled for the documentation and evaluation of retrospective data up to 6 months postoperatively.

NCT ID: NCT05053620 Completed - Cataract Clinical Trials

Astigmatism Correction With Intrastromal Arcuate Incisions in Eyes Undergoing Cataract Surgery With Femtosecond Laser Using the Cassini Ambient With Iris Registration (ARCUATAS)

ARCUATAS
Start date: October 19, 2021
Phase:
Study type: Observational

This is an observational, prospective follow-up post-marketing study of CE marked medical devices aimed at treating astigmatism in patients with cataracts. The main objective is to evaluate the response of the intrastromal arcuate incisions procedure for the correction of low corneal astigmatism with the Catalys femtosecond laser using the Cassini Ambient equipment with iris registration in cataract surgery.

The Comparative Clinical Performance of Two Daily Disposable Toric Contact Lenses

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

This study aimed to compare the clinical performance of two daily disposable toric contact lenses.

NCT ID: NCT04933487 Completed - Cataract Clinical Trials

Rotational Stability Analysis of a Toric Monofocal IOL

PHY2013
Start date: August 26, 2014
Phase: N/A
Study type: Interventional

This is a single-center, prospective PMCF study whereby patients undergoing routine cataract surgery will have monolateral implantation of hydrophilic monofocal toric intraocular lens Ankoris.

NCT ID: NCT04924231 Completed - Cataract Clinical Trials

Effect of 1.8-mm Steep-axis Clear Corneal Incision on the Posterior Corneal Astigmatism in Candidates for Toric IOL Implantation

Start date: February 1, 2017
Phase:
Study type: Observational

we aimed to analyze the effects of cataract surgery using a 1.8-mm steep-axis clear corneal incision (CCI) on the posterior corneal surfaces based on the keratometry from the rotating Scheimpflug imaging device (Pentacam HR) in candidates for toric intraocular lens (IOL) implantation

NCT ID: NCT04908488 Completed - Astigmatism Clinical Trials

Clinical Performance of Two Daily Disposable Toric Soft Contact Lenses

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

The purpose of this study is to compare the clinical performance of PRECISION1™ for Astigmatism (P1fA) contact lenses with 1-DAY ACUVUE MOIST® for ASTIGMATISM (AMfA) contact lenses.

NCT ID: NCT04903301 Completed - Myopia Clinical Trials

Patient Satisfaction With Contoura Vision Topography-Guided LASIK

Start date: May 21, 2021
Phase: N/A
Study type: Interventional

To evaluate patient reported outcomes associated with quality of vision before and after treatment with Contoura Vision Topography-Guided LASIK.

NCT ID: NCT04890249 Completed - Cataract Clinical Trials

Clinical Investigation of Two Tecnis Investigational Lenses

Start date: June 23, 2021
Phase: N/A
Study type: Interventional

This study is a 6-month, prospective, multicenter, randomized (1:1:1), subject-masked and evaluator-masked, bilateral clinical investigation of the TECNIS IOL Models C1V000 and C2V000 versus the TECNIS Eyhance™ Model ICB00 IOL. The study will be conducted at up to 15 sites in EU, AU, NZ and/or AP and will enroll up to 225 subjects to achieve approximately 67 bilaterally implanted subjects in each lens group. Allowing for 10% lost-to-follow-up, this will achieve approximately 60 evaluable subjects in each lens group at 1, 3, and 6 months. The eye implanted first will be considered the primary (monocular) study eye.

NCT ID: NCT04884672 Completed - Myopia Clinical Trials

PMCF Study on SMILE Treatment of Myopia With and Without Astigmatism

Start date: July 9, 2021
Phase:
Study type: Observational

The primary objective of this PMCF investigation is to systematically collect safety and effectiveness data with the VISUMAX 800 laser in clinical daily routine SMILE use for the purpose of post market surveillance.
