Active clinical trials for "Presbyopia"

The aim of this study is to evaluate the patient subjective experiences of the monthly multifocal lens when compared to the daily disposable multifocal lens after 15 minutes of daily wear.

This clinical trial investigates the differences between three different progressive addition lens designs. It is a non-invasive double-masked randomized clinical investigation. For this study, 80 participants will be recruited.

To compare refractive outcomes and patient's visual quality after bilateral cataract surgery when implanting multifocal intraocular lens, monofocal with monovision or hybrid monovision.

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.

The purpose of this study is to evaluate the visual performance of DACP MF and PROCLEAR 1D MF daily disposable contact lenses in an established presbyopic population.

The purpose of this study is to test the performance of an investigational multifocal test soft contact lens.

Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). Implantation of the IOLs is bilaterally.

Evaluation of mean preoperative and postoperative Corrected distance visual acuity (CDVA) after Refractive Lens Exchange in presbyopic patients

The objective of the study is to evaluate the performance of somofilcon A 1 day multifocal when worn on a daily disposable wear modality over a period of up to 3 weeks.
