The Effect of Masking on Subjective Results During Daily Disposable Contact Lens Studies
Summary
The objective of this pilot study is to explore the effect of masking on subjective ratings for two daily disposable contact lenses.
The study hypothesis is masking will have minimal impact on subjective outcomes.

Clinical Trials
Clinical Validation of the New Print on Focus DAILIES Toric
The primary objective of this trial is to validate the improvements made to the OK inversion indicator. Visibility on eye and on finger will be assessed by the subjects
The Clinical Comparison of Senofilcon A and Stenfilcon A Contact Lenses
The objective of this study is to compare the clinical performance of senofilcon A lens with the stenfilcon A lens each for one week of daily disposable wear.
Performance Comparison Between Comfilcon A and Senofilcon C Lenses
The aim of this study is to determine the clinical performance of comfilcon A in comparison to senofilcon C.
Performance Comparison Between Fanfilcon A and Senofilcon C Sphere Lenses
Prospective, multi-center, bilateral, double-masked, randomized, cross-over, daily wear, 1 month dispensing study (2 weeks each lens pair)
An Evaluation Of The Fitting Success Rate Of Senofilcon A Soft Contact Lenses In Three Designs.
This study will compare the on-eye fitting characteristics of three types of contact lenses. Each lens pair will be worn for 30 to 45 minutes before assessment and the results will be comp...

Medical and Biotech [MESH] Definitions
Myopia, Degenerative
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Scleroplasty
Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.
Photorefractive Keratectomy
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
Vitreous Detachment
Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility.
Myopia
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
