Post-market Clinical Follow-up Study of Alcon TOTAL30® Contact Lenses (Lehfilcon A)

Alcon Research129 enrolled

Overview

The purpose of this Post-Market Clinical Follow-Up (PMCF) study is to continuously assess the visual performance and safety of TOTAL30 Sphere and TOTAL30 for Astigmatism contact lenses in a real-world setting across a broad variety of patients through routine clinical practices.

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 TOTAL30 sphere or toric contact lens prescription was released. Baseline visit data will be collected retrospectively (chart review). The Year 1 visit is defined as the visit that occurs 1 year (-2/+6 months) since the Baseline visit during which period the subject is wearing test lenses of the same design in both eyes, and a contact lens examination is performed. Year 1 data will be collected either retrospectively or prospectively (eye exam).
