ClinConnect Summary

The North American Comfilcon A Clinical Study is testing different types of contact lenses—specifically, comfilcon A Sphere, Toric, Multifocal, Toric Multifocal, and Energys lenses—to see how safe and effective they are for people with vision problems like astigmatism, presbyopia, and ametropia. The goal is to ensure that these lenses work well for everyday use in the general population.

To participate in this study, you need to be between 8 and 75 years old and have been using one of the specified contact lenses for at least a year, including wearing them overnight occasionally. However, if you are currently involved in another clinical trial for contact lenses or their care products, you won’t be eligible. If you join the trial, you can expect to help researchers understand how these lenses perform, which could lead to better options for people who need vision correction.
