Refractive Errors Clinical Trial
Official title:
Post-market Clinical Follow-up Study of Alcon PRECISION1™ Spherical Soft Contact Lenses (Verofilcon A) and PRECISION1T™ for Astigmatism Contact Lenses (Verofilcon A)
The purpose of this study is to assess long term performance and safety of verofilcon A soft contact lenses in a real-world setting in a population of 7 years or older having at least 1 year of verofilcon A (sphere or toric) contact lens wear in a daily wear and daily disposable modality.
This study consists of a Baseline Visit and a Year 1 Visit. The Baseline Visit is defined as the first office visit where an eye care professional provided an in-person office biomicroscopy exam to the subject before or during which a PRECISION1™ sphere or toric contact lens prescription was released. The Baseline Visit will be retrospective, with all assessments obtained from chart review. The Year 1 Visit is defined as the visit that occurs 1 year (-2/+4 months) since Baseline during which period the subject is wearing test lenses of the same design in both eyes and a contact lens examination is performed during the visit. The Year 1 Visit may be prospective or retrospective. ;
