NCT ID: NCT02193555 Completed - Presbyopia Clinical Trials

Visual Performance of Prototype Contact Lens Designs

Start date: July 2014
Phase: N/A
Study type: Interventional

The aim of this study is to assess the visual performance of prototype soft contact lens designs compared to a commercially available contact lens

NCT ID: NCT02103309 Completed - Myopia Clinical Trials

Comparative Evaluation of Contact Lens Centering of DAILIES® AquaComfort Plus® Versus 1-DAY ACUVUE® MOIST® in Japan

Start date: October 2013
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate lens centration and subjective impressions of DAILIES® AquaComfort Plus® (DACP) lenses compared to 1-DAY ACUVUE® MOIST® (1DAM) lenses in ball sports players.

NCT ID: NCT02100410 Completed - Myopia Clinical Trials

On-Eye Evaluation of Contact Lens Axis Location

Start date: April 2013
Phase: N/A
Study type: Interventional

The purpose of this study was to evaluate the axis location of toric contact lenses after 3 minutes of wear. During this 1-visit study, each participant wore 3 pairs of study lenses of various design iterations (2-87-1, 2-87-2, 2-87-3) for an exposure time of approximately 30 minutes each. Each pair consisted of lenses of the same design iteration, 1 lens with embossed mark [TEST1 (T1), TEST3 (T3), TEST5 (T5)], worn on the right eye, and 1 lens without embossed mark [TEST2 (T2), TEST4 (T4), and TEST6 (T6)] worn on the left eye.

NCT ID: NCT02089191 Completed - Refractive Error Clinical Trials

Tear Film Stability of DAILIES® AquaComfort Plus® Contact Lenses vs. MyDay® Daily Disposable Contact Lenses

Start date: March 2014
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate tear film stability of DAILIES® AquaComfort Plus® (DACP) compared to MyDay® after 12 hours of lens wear.

NCT ID: NCT02072980 Completed - Refractive Error Clinical Trials

DAILIES TOTAL1® Lubricity Post Wear

Start date: March 2014
Phase: N/A
Study type: Interventional

The primary objective of the study is to demonstrate that the lubricity of DAILIES TOTAL1® (DT1) lenses after 16 hours of wear is equivalent to the lubricity of unworn DT1 lenses.

The purpose of this study is to compare the change from baseline in central corneal curvature at one week, between 2 silicone hydrogel lenses, in higher myopic subjects.

NCT ID: NCT02055404 Completed - Refractive Error Clinical Trials

On-Eye Evaluation of Contact Lens Rotation Marks

Start date: February 2013
Phase: N/A
Study type: Interventional

The purpose of this study was to select the size of the molded rotation mark for a new toric contact lens by comparing the visibility of various molded rotation marks.
