简要总结
Dry eye disease (DED), also called keratoconjunctivitis sicca, is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film and accompanied by symptoms such as ocular discomfort and visual disturbance.
Tear Film & Ocular Surface Society Dry Eye Workshop (TFOS DEWS) II recommends individualized management of DED based on the relative contribution of aqueous deficient and evaporative pathophysiology (to the extent that this can be determined), as well as disease severity.
First-line for treating dry eye consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants.
Carboxymethyl cellulose (CMC) is one of the most common viscous polymers used in artificial tears to achieve prolonged residence time on the ocular surface.
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 "Ocular drops based upon carmellose" 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 "Ocular drops based upon carmellose" according the Instructions for Use (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 "Ocular drops based upon carmellose" products can be dispensed to the enrolled subject, depending on Investigator clinical evaluation and decision.
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 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) and their eye-surgery history (if applicable).

结局指标
主要结局
Change in Schirmer Test I: to evaluate the lubricant and protecting performance of the "Ocular drops based upon carmellose" used as Intended in subjects with mild or severe dry eye syndrome, through the Schirmer I test
时间窗: From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)
次要结局
- Change in Tear Break-up Time (TBUT): to evaluate the performance of the "Ocular drops based upon carmellose" used as Intended to ensure relief from ophthalmic stress, through the TBUT test(From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2))
- Change in Ocular Surface Disease Index (OSDI): to evaluate the eye-discomfort relieving performance of the "Ocular drops based upon carmellose", through OSDI(From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2))
- To evaluate the safety and tolerability of the "Ocular drops based upon carmellose", through Visual Analogue Scale (VAS) - evaluation of symptoms related to dry eye disease (burning, fatigue, discomfort, redness)(End of study visit (EOS/V2 = Day 30 ± 2))
- To evaluate the patient satisfaction through a Rensis Likert 5 points patient satisfaction scale(End of study visit (EOS/V2 = Day 30 ± 2))
