Active clinical trials for "Myopia"

This is a 1-week dispensing, double-masked, randomized, bilateral study comparing the test lens against the control lens.

To compare the outcomes of a toric Implantable Collamer Lens (ICL) and a spherical Implantable Collamer Lens combined with astigmatic keratotomy (AK) in the correction of high myopic astigmatism.

The aim of this study is to compare the subjective performance of the comfilcon A contact lens against lotrafilcon B contact lens after 4 weeks of reusable lens wear.

The initial subjecting handling experience of neophyte contact lens wearers with Precision1 will be compared to that with a daily disposable lens which mas been on the market for numerous years (1-Day ACUVUE Moist).

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 compared to mathematically calculated fitting characteristics.

To evaluate the comparative clinical performance of the fanfilcon A silicone hydrogel lens used in daily wear and to compare this with competitive hydrogel lens products.

This work aims at the analysis of ocular aberrations induced by wave front optimized ablation profiles WFO using I-Trace aberrometer (Ray -Tracing)

The purpose of this study is to assess the clinical performance of an investigational contact lens over 30 days of daily wear.

The main objective of the study is to refit existing soft lens wearers with two different daily disposable contact lens types, Lens A and Lens B, to determine their performance after one week of wear.

The purpose of this study is to document the programmed flap thickness to achieved flap thickness using the FS200 femtosecond laser in performing LASIK procedure. The FS200 Femtosecond laser is a precision surgical device that is used to create a flap in a FDA approved LASIK procedure.
