Clinical Performance Evaluation of Two Daily Disposable Silicone Hydrogel Toric Contact Lenses

Clinical Trial ID: NCT04254003


The purpose of this study is to evaluate the rotational behavior of DT1 Toric contact lenses.

This is a single visit, non-dispense study where subjects will be exposed to the test and control lenses for approximately 1 hour each.


Inclusion Criteria: - Current wearer of any commercial soft daily wear contact lens with at least 3 months of wearing experience with a minimum wearing time of 5 days per week and 8 hours per day. - Requiring contact lens (manifest refraction) of a cylindrical power of -0.75 to -2.50 diopter cylinder (DC). - Best corrected distance visual acuity 20/25 or better Snellen in each eye (as determined by manifest refraction at screening). - Willing to NOT use rewetting/lubricating drops at any time during the study. Other protocol-defined inclusion criteria may apply. Exclusion Criteria: - Any anterior segment infection, inflammation, or abnormality or disease (including systemic) that contraindicates contact lens wear, as determined by the Investigator. - Any use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the Investigator. - History of refractive surgery or plan to have refractive surgery during the study or irregular cornea in either eye. - Eye injury in either eye within 12 weeks immediately prior to enrollment for this trial. Other protocol-defined exclusion criteria may apply.
