Active clinical trials for "Presbyopia"

Correlating the accuracy of a refraction done over telemedicine to that of a standard refraction, with a study hypothesis that the results will be equivalent.

The purpose of the trial is to clinically evaluate the performance of a progressive addition lens among presbyopic patients. This evaluation will be done by performing visual tests and collecting subjective information from subjects wearing the lens which will be manufactured according to personal prescription.

Clinical outcome of extended-depth-of-focus intraocular lens (SAV) implantation

The current study aims to assess the use of pilocarpine and brimonidine to improve near visual acuity in patietns with monofocal intraocular lenses. Thirty-three subjects with be enrolled and baseline visual acuity with be measured at near and distance. This will be compared to visual acuity after drop administration over 6 hours. A quality of life questionnaire will also be evaluated.

The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes implanted under a corneal flap or within a small-incision pocket.

This is to evaluate the satisfaction of patient and physician about short-distance, medium-distance, long-distance postoperative vision and eyeglass dependence, glare, and visual acuity after insertion of the TECNIS® Symfony or TECNIS® Symfony Toric intraocular lens.

The objective of this study is to evaluate the product performance of an investigational multifocal low add soft contact lens.

In this study, you will wear an invesetigational contact lens, Apioc-P or Apioc-PT, the way you wear your current contact lenses for approximately one month (no more than 35 days).

The clinical investigation objective is to evaluate safety and performance outcomes of trifocal IOL implantation to improve vision in patients with cataract and/or ametropia (hyperopia, myopia) and/or presbyopia. Retrospective data from preoperative status up to 12 month postoperative status will be collected from patients that were implanted with Medicontur's 640PM intraocular lens: Preoperative status: Preoperative Screening and Baseline Surgery: IOL implantation M1: 1 month +/- 2 weeks postoperative follow-up M3: 3 months +/- 1 month postoperative follow-up M12: 12 months +/- 3 months postoperative follow-up

The purpose of this clinical study is to assess the repeatability of objective refraction using auto refraction on subjects bilaterally implanted (implanted in both eyes) with the Fluid Accommodating IOL (FAIOL).
