Filter by:This study will be a 12-month, prospective, multicenter, open-label, non-comparative, non-randomized clinical investigation conducted at 8 to 14 sites. A total of 383 subjects will be enrolled to achieve approximately 268 treated subjects, resulting in at least 241 evaluable subjects at the point of refractive stability. After signing the informed consent, subjects meeting all inclusion and exclusion criteria in both eyes may be scheduled for surgery. The follow-up visit schedule will be the same for each operative eye.
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.
The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes treated with low dose, short duration Mitomycin C (MMC) during surgery and an extended low dose steroid regimen after surgery.
The purpose of this study is to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls. There are two phases in this study. The first phase is an observational phase which studies the eye in various conditions. The second phase is an interventional phase which studies the changes in the eyes after taking an over-the-counter medical food (Ocufolin) for 6 months.
The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopic patients with treatments to optimize the ocular surface before corneal inlay surgery.
Patients who underwent bilateral bifocal or trifocal lenses implantation for presbyopia correction with monofocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require: a) distant vision (DV), (ie. driving), b) intermediate vision (IV), (ie. computer word processing), c) near vision (NV), (ie. book reading). Primary objective of the study is the comparison in a series of ADLs of two cohorts of patients (group 1: subjects with bilateral bifocal lenses implantation, group 2: subjects with bilateral trifocal lenses implantation)
This study is aimed at presbyopic patients that do not require magnifying glass at close rage. The purpose of this study is to investigate the functional and physiological changes in eye induced by pinhole glass.
The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision.
Patients who underwent mini-monovision (with bilateral myopic defocus, MM-BMD) surgery for presbyopia correction with monofocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require: a) distant vision(DV), (ie. driving), b) intermediate vision (IV), (ie. computer word processing), c) near vision (NV), (ie. book reading). Primary objectives of the study are: 1) the development of a series of tasks in a research setting that will simulate common ADLs that require DV, IV, and NV. 2) the identification of potential correlations of the tasks in the research setting with demographic, clinical and other parameters of the study participants.
