Active clinical trials for "Presbyopia"

Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Different options are available. These options include: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocals and extended depth of focus (EDOF) IOLs. In a previous study, the visual outcomes of the EDOF Toric IOL were evaluated when both eyes were targeted for plano and when the non-dominant eye was set for a small residual myopic error (-0.50 D) or nanovision in patients with astigmatism. The nanovision approach, appeared to provide similar binocular acuity at distance and intermediate but better acuity at near. The purpose of this study is to evaluate the visual outcomes of an EDOF IOL when combined with a multifocal IOL with a +3.25 D add in patients with or without astigmatism undergoing routine cataract surgery.

Prospective, controlled, single-surgeon, single-center post-market clinical follow up study to investigate the clinical outcomes of a hydrophobic trifocal IOL (PhysIOL POD F GF)

Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs with different material (hydrophobic and hydrophilic) from the same manufacturer. Implantation of the IOLs is bilaterally.

The primary objective of this study is to demonstrate noninferiority in visual acuity at distance when wearing the test contact lenses (LID210464) compared to the control contact lenses (AOHG MF) after 30 days of wear.

The objective of this study is to evaluate the performance of a novel multifocal lens system.

This is a prospective, multi-centre, randomised, single-blind, cross-over study to compare the BIOFINITY® MULTIFOCAL lens and respectively the AIR OPTIX® AQUA MULTIFOCAL lens (lenses allocated on a ratio of 1/0.5) and the PUREVISION® MULTIFOCAL lens (lenses allocated on a ratio of 1/0.5), in presbyopic patients.

This study is designed to compare the relative performance related to subjective and objective vision between two multifocal soft contact lenses.

The purpose of this study is to prospectively evaluate postoperative visual and refractive parameters in a series of subjects bilaterally implanted with Presbyopia-Correcting Intraocular Lenses (IOLs).

This study compares two fitting approaches to multifocal contact lenses.

The purpose of this clinical trial is to assess the clinical performance of LID#224381 Multifocal (MF) contact lens and Air Optix plus HydraGlyde (AOHG), a commercially available MF contact lens. Eligible subjects will wear each study lens type in a cross-over fashion for approximately 2 days.
