About

This study is a prospective, randomized, open-label, two arms, clinical study aim to evaluate the efficacy and safety of treatment with Hyper-CL™ lens + Antibiotics compared with treatment with Antibiotics only, in subjects with Bacterial keratitis.

The design of the Hyper-CL™ lens increases contact time of the antibiotics on the cornea enabling increased bioavailability of the active drug.

Full description

The Hyper-CL™ Therapeutic soft contact lenses for short-term wear (up to 7 days) are indicated for therapeutic use to promote corneal healing and relieve corneal pain by protecting the cornea during the treatment of acute or chronic pathologies, such as corneal edema, corneal erosions, entropion, bullous keratopathy, and corneal dystrophies as well as post-surgical conditions resulting from cataract extraction and corneal surgery.
