NCT ID: NCT04075591 Recruiting - Refractive Error Clinical Trials

Wavefront-guided LASIK for Monovision Treatment of Myopic Subjects With Presbyopia

Start date: September 24, 2019
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03825081 Recruiting - Presbyopia Clinical Trials

Pilocarpine and Brimonidine in Patients With Monofocal Lenses

Start date: January 21, 2019
Phase: Early Phase 1
Study type: Interventional

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.

NCT ID: NCT03376412 Recruiting - Presbyopia Clinical Trials

A Study to Evaluate the Raindrop Near Vision Inlay Under Flap or Within Pocket

Start date: December 8, 2017
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT03242317 Recruiting - Presbyopia Clinical Trials

A Prospective Study to Evaluate the Raindrop Near Vision Inlay With Mitomycin C

Start date: June 16, 2017
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT03135327 Recruiting - Multiple Sclerosis Clinical Trials

Clinical Applications of Advanced Ophthalmic Imaging

Start date: January 1, 2007
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03126877 Recruiting - Presbyopia Clinical Trials

A Prospective Study to Evaluate the Raindrop Near Vision Inlay in Presbyopic Patients With Treatments to Optimize the Ocular Surface Before Implantation

Start date: April 10, 2017
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT03021512 Recruiting - Presbyopia Clinical Trials

Functional Assessment of ADL in Patients Who Underwent Bifocal and Trifocal Presbyopic Correction

Start date: January 2017
Phase: N/A
Study type: Observational

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)

NCT ID: NCT02722291 Recruiting - Presbyopia Clinical Trials

Functional and Physiological Changes Induced by Pinhole Glasses in Presbyopia

Start date: March 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02668523 Recruiting - Presbyopia Clinical Trials

A Clinical Trial to Evaluate a Corneal Inlay for the Improvement of Near and Intermediate Vision in Pseudophakic Presbyopic Subjects

Start date: December 2015
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT02431156 Recruiting - Presbyopia Clinical Trials

Functional Assessment of Activities of Daily Living (ADL) in Patients Who Underwent Mini-monovision Correction

Start date: March 2015
Phase: N/A
Study type: Observational

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.
