Active clinical trials for "Presbyopia"

Compare postoperative Subjective and objective visual quality and economic efficiency of different Intraocular Lens(IOLs) implantation designed for the correction of presbyopia.

The objective is to assess refractive accuracy of the Alcon Vision Suite (with Argos biometer) following Clareon PanOptix and AcrySof Vivity IOL implantation.

Primary objective of this study is to evaluate and compare the measurements of two different optical biometrics systems in patients who will undergo cataract surgery or presbyopia surgery using intraocular lenses (IOL-PC).

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 that evaluated 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 showed good outcomes with high patient satisfaction and less dependance on glasses for intermediate and near activities. As technology evolves, new lens models are available in the market. The purpose of this study is to evaluate the latest EDOF and a hybrid multifocal lenses when combined.

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. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D with no more than 0.75 D of refractive cylinder. The Raindrop Near Vision Inlay will be implanted in the non-dominant eye.

The introduction of presbyopia-correcting intraocular lenses (PC-IOLs) has provided cataract and refractive surgeons the ability to provide patients with a wider range of visual success and spectacle independence post-cataract surgery.Multifocal (MFIOL) IOLs have the ability to provide near and distance vision, and in the case of trifocal IOLs, near, intermediate and distance. Despite the significant technological evolution of MFIOL's, the potential for visual disturbances, such as glare, halos and starbursts still exists-and in much greater frequency compared to their monofocal counterparts. Extended depth of focus (EDOF) IOLs aim to provide patients with a functional range of vision, with a similar visual disturbance profile to a monofocal lens. In this way, this subset of PC-IOL's can offer patients some degree of spectacle independence, with a significantly lower incidence of visual disturbances. The Vivity Extended Vision IOL is the first of its kind to offer Wavefront Stretching technology, providing patients with an excellent extended range of vision from intermediate to distance, as well as some functional near vision. Prior studies have demonstrated very good vision in both bright and dim lighting conditions, as well as a high degree of spectacle independence with the Vivity IOL, as compared to a monofocal IOL. Studies evaluating the ability of the Vivity IOL to provide a significant impact on patient lifestyle (e.g. patient independence from spectacles for most activities with a low rate of visual disturbances) in the United States in a 'real-world' setting have yet to be performed. In addition, influence of pre-and-perioperative variables such as sex, age, prior refractive surgery, IOL formula used, axial length, astigmatism, use of intraoperative aberrometry, femtosecond laser and pupillary expansion devices has yet to be evaluated on the postoperative success of this IOL. This study will be comprised of patients with visually significant cataracts who will undergo cataract extraction with implantation of the spherical and/or toric models of the Vivity Extended Vision (Alcon, Fort Worth TX) intraocular lens. Upon decision of the patient and surgeon to undergo surgery, patients will be offered the option to enroll in this observational study.

Study of safety and efficacy of UNR844 in subjects with presbyopia.

The study will evaluate whether the LensAR laser system can be used in the lens of the eye to increase the ability to read and/or see near objects

A new minimally invasive procedure for treating presbyopia is being evaluated to determine if there is improvement in near and intermediate vision after treatment
