Active clinical trials for "Presbyopia"

The objective of the study was to adapt existing multifocal soft lens wearers to a CONTROL lens for 2 weeks and then evaluate the success of switching them to the TEST lens, with a review after 2 weeks.

The purpose of this study is to demonstrate non-inferiority of a new daily disposable multifocal contact lens in plus powers against the commercially available AIR OPTIX® AQUA MULTIFOCAL (AOAMF) lens in high contrast/high illumination (HC/HI) near visual acuity (VA).

The objective of this study is to evaluate the product performance of the investigational multifocal high add soft contact lens compared with PureVision Multi-focal contact lens on a daily wear basis.

The aim of this study is to assess visual performance of prototype soft contact lens designs compared to commercially available contact lenses over one-week of lens wear.

A comparative evaluation of a newly marketed multifocal contact lens with a single vision contact lens when used with near vision spectacles. The evaluation was to quantify the difference between the two test corrections.

The purpose of this trial is to compare the performance of two multifocal contact lenses.

The purpose of this study is to compare the overall performance of a monthly replacement contact lens when worn for one month and when worn for two weeks.

To prospectively evaluate postoperative visual and refractive parameters in a series of subjects bilaterally implanted with AcrySof ReSTOR +3 vs. those bilaterally implanted with LENTIS MPlus Intraocular Lens (IOL).

A. The primary purpose of the study is to evaluate outcomes of aphakic eyes implanted with the IC-8 IOL following cataract removal in prior inlay patients after KAMRA inlay removal. B. The secondary purpose of the study is to determine whether there are any changes in biometry measurements before and after the inlay removal and how the changes affect the calculated IOL power.

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)
