PMCF Study to Evaluate Performance and Safety of "Distilled Waters-based Eyedrops" Used to Relieve Dry Eye Symptoms

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a common ocular condition characterized by a loss of homeostasis of the tear film and inflammation of the ocular surface. The typical symptoms of DED include irritation, discomfort, blurred or fluctuating vision.

Over the counter (OTC) artificial tears are typically the first line of dry eye treatment; they are meant to supplement the tears that cover the eye's surface. OTC products mimic the different layers of the tear film in order to maintain ocular hydration.

Distilled waters of natural herbs such as Green Tea, Calendula, Chamomile, Hamamelis and Euphrasia are known for their soothing and refreshing properties. Thanks to the combined action of these natural elements, distilled waters-based eyedrops are particularly indicated to relieve eye dryness, irritation and redness of the eyes' mucosa caused by atmospheric agents, environmental factors, and/or use of contact lenses.

"Distilled waters-based eyedrops" medical devices are ophthalmic solutions containing distilled waters able to relieve eye discomfort thanks to their soothing and refreshing action.

For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Distilled waters-based eyedrops" used as intended to relieve dry eye symptoms.

The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "Distilled waters-based eyedrops" according to the IFU.

Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed.

At baseline visit (V0), one of the "Distilled waters-based eyedrops" products will be administered to the enrolled subject.

The patient will perform 2 on site visits (V0 and V2/EOS). To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.

The first administration and the intervals at which the treatment should be repeated, to be done as per Investigator judgment and according to the IFU, depend on various factors regarding the physiology of the patients (e.g. type of eye-tear film, anatomy, age), their lifestyle (e.g. use of computer, wearing of contact lenses).
