Active clinical trials for "Cataract"

Prospective survey study of patients who previously underwent cataract surgery with the Alcon PanOptix or PanOptix Toric intraocular lens in both eyes.

This study will compare two methods of vacuum (peristaltic or venturi) commonly used during the removal of a femtosecond treated cataract. The investigators will observe which method uses less energy, is gentler on the eye, reduces corneal swelling and if the vision recovers faster with one method compared to the other.

Objective and Principle: To evaluate whether enlarging the incision can reduce corneal complications associated with phacoemulsification with regular 2.2 mm incision. The aim of this study: To evaluate whether the technique of enlarging internal incision could reduce the incidence of descemet membrane detachment after 2.2 mm incision phacoemulsification. Secondary outcome: To evaluate whether the technique of enlarged internal incision can reduce other corneal complications such as corneal edema and astigmatism after 2.2 mm incision phacoemulsification. Study Design: A prospective randomized controlled study

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.

Determine the consequences of COVID-19 pandemic on routine targeted surgeries. Five surgical procedures were considered : cataract surgery, hip and knee arthoplasties, coronary revascularisation by angioplasty and definitive cardiac stimulation. The objective of the study is to quantify changes of these procedures in 2020 and in 2021 (up to June) compared to 2019 taking into account their annual evolution and according to the type of operation (primary or reoperation/revision) and emergency status, if applicable.

Prognostic factors determining visual outcomes in patients with posterior polar cataracts and posterior lenticonus are largely unknown. In this trial, the investigators aimed to evaluate the visual outcomes in patients with posterior polar cataracts and posterior lenticonus and try to find out the factors associated with the visual acuity after surgery. Patients enrolled in this study will be followed for at least 6 months and will have study visits at 1 day, 1 week, 1 month, 3 month, 6 month postoperatively.

The objective is to assess the visual outcomes and quality of vision of patients receiving the AcrySof® Vivity Intraocular lens (IOL), when implanted in eyes with high ocular axial length (≥24.5mm), after uneventful cataract surgery.

This study will examine patient satisfaction and spectacle independence using a survey in patients who have undergone uncomplicated cataract surgery with a presbyopia-correcting lens at least 2 years prior to administration of the survey.

To validate a high-definition (HD) three-dimensional (3D) visualization system in cataract surgery

Investigate the intraocular pressure(pressure inside the eye) of patients who are treated with Lotemax after undergoing cataract surgery.
