Active clinical trials for "Presbyopia"

In this clinical trial, a total of 75 presbyopic patients in the age range of 40 to 60 years old will be participated. The right eyes of 45 patients will be treated by Biocarpine® and they will be considered as the case group, their left eyes will be defined as the controls. In another case group, the right eyes of 30 patients will received Vuity® eye drops and their left eyes will be considered as controls.

The study objective was to gather short-term clinical performance data for two soft multifocal contact lenses.

VTI has an FDA cleared soft contact lens product. Its optical design creates an enhanced depth of focus (EDOF), which provides clear distance, intermediate, and near vision. This study is to quantify the enhanced depth of focus and visual impact.

The objective of this study is to evaluate the product performance of a new silicone hydrogel daily disposable multifocal contact lens, the Bausch + Lomb (kalifilcon A) Daily Disposable Multifocal Contact Lens, when worn by current soft contact lens wearers on a daily disposable wear basis

To explore the wear experience in Dailies TOTAL1 Multifocal contact lenses in presbyopic adults who have previously dropped out of contact lens wear.

The objective of this study is to obtain an additional 36 months of safety and effectiveness data from all subjects who were implanted with the VisAbility™ Micro Insert in the VIS-2014 clinical trial.

The intended purpose of the investigational device in the study is the correction of myopia and myopia with astigmatism in the CE (Conformité Européene) approved range and optimized for presbyopic patients using the treatment option HiSMILE, installed on the VisuMax femtosecond laser.

The purpose of this Post-Market Clinical Follow-up study is to describe the long-term safety and performance of the Clareon Vivity and Vivity Toric and Clareon PanOptix and PanOptix Toric IOLs.

This clinical investigation is a prospective, multicentre, non-comparative case series to assess safety and efficacy of CorVision® bioengineered corneal inlay for improving uncorrected near vision in presbyopic subjects. In this study a sterile medical grade collagen-based bioengineered corneal inlay (CorVision®), which closely mimics the human corneal tissue, will be tested as a natural microlens for correction of near vision in presbyopic patients. The primary endpoint for this study is to further determine the safety of the inlay and the secondary endpoint is to determine the efficacy of the inlay to improve uncorrected near vision. CorVision® implantation will be done via a minimally invasive laser-assisted intra-stromal surgery. Besides important information concerning details of the surgical method and postoperative care, tolerance of the device and possible adverse events will be reported along with several clinical parameters to be measured preoperatively and postoperatively. The study will consist of 110 subjects receiving the inlay to be included within a recruitment period of 18 months at multiple clinical sites. All subjects will be followed for minimum 12-months postoperatively. Postoperative evaluations are scheduled at 1 week, 1, 3, 6, and 12 months.

A minimally invasive procedure for treating presbyopia is being evaluated to determine if there is improvement in near and intermediate vision after treatment.
