Active clinical trials for "Presbyopia"

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.

This non-dispensing study is to evaluate the clinical performance of a test multifocal toric silicone hydrogel contact lens compared to a marketed multifocal toric contact lens (control).

The purpose of this study is to evaluate the visual performance of a new multifocal High ADD contact lens compared to the currently-marketed AIR OPTIX® AQUA MULTIFOCAL (AOAMF) High ADD Contact Lens.

The purpose of this study was to demonstrate substantial equivalence of the new DAILIES® AquaComfort Plus® Multifocal (DACP MF) contact lens to the commercially available Focus® DAILIES® Progressives (FDP) contact lens.

The purpose of this clinical study is to evaluate DAILIES TOTAL1® Multifocal (DT1MF) contact lenses compared to 1-DAY ACUVUE® Moist® Multifocal (AMMF) contact lenses for investigator-graded lens centration in a Japanese population.

The purpose of the current study was to compare the visual performance after bilateral implantation of the Panoptix IOL , or the AT LISA IOL or Tecnis Symfony IOL . The focus was on intermediate vision, defocus curves, and contrast sensitivity.

The purpose of this study is to evaluate visual and refractive parameters in a series of subjects bilaterally implanted with presbyopia-correcting intraocular lenses (IOLs) during cataract surgery.

The purpose of this study is to compare two multifocal contact lenses in presbyopic wearers.

By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: How accurately this combined technique corrects distance and near vision Whether the correction is adequate to remove the complete need for supplementary near spectacles

The purpose of this study is to prospectively evaluate postoperative visual and refractive parameters in a series of subjects bilaterally implanted with the AcrySof® IQ ReSTOR® +3 versus those bilaterally implanted with the Tecnis Multifocal 1-piece.
