NCT ID: NCT03228199 Completed - Presbyopia Clinical Trials

PROductivity Study of Presbyopia Elimination in Rural-dwellers (PROSPER)

PROSPER
Start date: July 24, 2017
Phase: N/A
Study type: Interventional

This trial seeks to establish, using a randomized, controlled design, the impact of near eyesight correction on the productivity of presbyopic agricultural workers in India, as measured by weight of tea picked.

NCT ID: NCT03226561 Completed - Presbyopia Clinical Trials

Assessment of Near Vision Capacity in Different Light Conditions Following Bilateral Trifocal Intraocular Implantation

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Patients who underwent presbyopic correction with bilateral trifocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require near vision acuity (NV), (ie. book reading). However, it is known that light intensity and temperature has a great impact on near vision capacity. Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and temperature) for ADLs that demand near vision acuity for a sample of patients who underwent presbyopic correction with bilateral trifocal intraocular lenses implantation

NCT ID: NCT03201562 Completed - Presbyopia Clinical Trials

A Single-Center, Double-Masked Evaluation of the Efficacy and Safety of PRX-100 in the Treatment of Early to Moderate Presbyopia

Start date: April 30, 2017
Phase: Phase 2
Study type: Interventional

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

NCT ID: NCT03173664 Not yet recruiting - Presbyopia Clinical Trials

Post-Approval Study With the KAMRA Inlay

Start date: July 31, 2018
Phase:
Study type: Observational

KAMRA inlay, to be unilaterally implanted into the cornea of a subject's non-dominant eye. The inlay is to be inserted into a stromal pocket created with a surgical femtosecond laser.

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: NCT03118934 Completed - Presbyopia Clinical Trials

Assessing Fitting Guides in Alcon Multifocal Contact Lenses

Start date: May 17, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to compare an alternative fitting guide to a current fitting guide for optimizing contact lens parameters and determining contact lens prescription.

NCT ID: NCT03117426 Completed - Cataract Clinical Trials

A Randomised Evaluation of Visual Function After Bilateral Implantation of Two Types of Presbyopia-correcting IOLs

Start date: January 1, 2017
Phase: N/A
Study type: Interventional

Since the introduction of intraocular lenses (IOL) in the treatment of cataract, the postoperative accommodative loss of the human eye has been a trending topic. Numerous studies show a high rate of spectacle-independency after bilateral implantation of multifocal IOLs (MIOL). However, glare, halos, and reduced visual acuity under different light conditions are common complaints after MIOL implantation. Due to its unique design, the TECNIS® Symfony Extended Range of Vision ZXR00 IOL (Abbott Medical Optics, Santa Ana, USA, hereinafter referred to as Symfony IOL) is theoretically providing a continuous range of high-quality vision for far, intermediate, and near distances with the same low incidence of halos and glare associated with monofocal IOLs under different light conditions. The goal of this study is to compare the AT LISA tri 839MP IOL (Carl Zeiss Meditec AG, Jena, Germany, hereinafter referred to as AT LISA IOL) versus the Symfony IOL in terms of postoperative achieved visual acuity at different distances, patient satisfaction (e.g. spectacle-independency, QoL), and postoperative complication profile (e.g. halo's and glare) under different light conditions. So far, there are no published studies comparing both IOLs. Therefore, we will perform this randomized control trial.
