ClinConnect Summary
This clinical trial is testing a new type of contact lens called delefilcon A, specifically looking at how well these lenses fit people with refractive errors, such as myopia (nearsightedness). The study will evaluate lenses with different shapes and sizes to see which ones provide the best comfort and vision.
To participate in this trial, you need to be someone who currently wears soft contact lenses for at least six hours a day, five days a week, and can wear lenses with specific prescriptions between -2.00 and -4.00 diopters. You'll also need to have good vision with your current lenses. However, if you have any eye infections, have had eye surgery, or have certain eye conditions, you won't be eligible for this study. While the trial is not yet recruiting participants, it aims to gather important information about the fit of these new lenses, so if you qualify, you could help improve contact lens options for others.
