Active clinical trials for "Presbyopia"

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

A prospective study to evaluate the feasibility of a new treatment algorithm to increase depth of focus after wavefront-guided LASIK correction of myopic refractive errors with the iDesign Advanced Wavescan Studio™ System and Star S4 IR™ Excimer Laser System. The purpose of this study is to determine whether wavefront-guided LASIK correction of myopic refractive errors with CustomVue combined with iDesign 1.3-PRESBY (presbyT-LASIK) treatments mitigate the effects of presbyopia by increasing the depth of focus compared to iDesign CustomVue treatments.

The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes implanted in corneal pockets with a delayed or a non-delayed approach.

This is a single visit study to evaluate the visual outcomes and patient satisfaction of patients who were bilaterally implanted with the Tecnis Synergy IOL between June 1 and December 31, 2021 in 2 centers in USA

This is a research study designed to test the utility of D-shaped bifocal lenses and PRIO Computer Lenses for persons using a computer. We hypothesize that lenses specially designed for computer use may allow more comfortable and productive work on a computer.

The purpose of this trial was to compare the functional visual performance of Precision Profile Multifocal (MF) contact lenses to Progressive Addition Lens (PAL) spectacles in a presbyopic population.

This is a multi-center, double-masked, vehicle-controlled study. The purpose of the study is to evaluate the safety of CSF-1 compared with vehicle in presbyopic subjects. Subjects will be treated for at least 6 weeks.

A study to Establish Safety, Tolerability, and Efficacy of PresbiDrops (CSF-1) in Presbyopic Subjects.

To evaluate the safety and efficacy of PRX-100 compared with aceclidine alone and vehicle in the treatment of early to moderate presbyopia.

The purpose of this study is to evaluate possible changes of angle kappa after multifocal intraocular lens implantation. Presumable influencing factors of postoperative visual axis shift (ie. biometric parameters of the eye) are investigated to determine the degree and direction of angle kappa alterations.
