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. The reported prevalence of DED estimates vary widely, from 5% to 33%, which may reflect both differing populations and inconsistent diagnostic criteria. Patients with moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. First-line therapy for treating dry eye consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants.
Sodium hyaluronate (commonly referred to as hyaluronic acid or HA) is a naturally occurring polymer and is ubiquitous throughout the interstitial cellular space in humans. It helps retain moisture in different types of tissue throughout the human body and aids lubrication between layers of tissue to eliminate friction - thus making it an ideal physiological tear film substitute.
As a result of its coiled structure and large hydrophilic domains, HA attracts and retains a large amount of water, and therefore possesses the ability to retard water evaporation. Following instillation, HA-based solutions effectively moisturize the eye surface and prolong the beneficial wetting effect over time.
Hyaluronic acid does not alter the normal surface of the eye like other types of tear substitutes. It closely mimics the properties of a normal, healthy tear film, with a longer retention time on the corneal surface than a cellulose-based tear substitute.
HA gels have also been used successfully in ophthalmic surgery for many years. As a result of their unique physical and chemical properties, HA solutions are similar to natural tears. For that reason, they are widely used in ophthalmology as lubricant eye drops for the treatment of sensations of ocular dryness.
For these reasons, an interventional, confirmative, post marketing clinical follow-up (PMCF) study was planned to evaluate the performance and safety of HA-based ophthalmic solutions (i.e. Irilens; Iridina; Afomill Lubricating Eye Drops) used to relieve dry eyes symptoms.
The objectives of this 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 three investigational products (IPs) containing HA as key ingredient.
The IPs are on the market with the following brand names:
- Irilens;
- Iridina;
- Afomill Lubricating Eye Drops.
Primary
• To evaluate the performance of IPs used as intended to relieve dry eye symptoms.
Secondary
- To evaluate the efficacy of IPs used as intended to relieve symptoms of DED.
- To evaluate the safety and tolerability of the IPs.
- To evaluate the patient satisfaction of the IPs.

结局指标
主要结局
Evaluate the performance of Investigational Products to relieve symptoms of dry eye. The performance will be evaluated by Shirmer I test at baseline (V0) and end of study visit (change will be assessed)
时间窗: Day 0 (baseline visit the IP will be dispensed) and Day 25
To evaluate the performance of IPs to relieve symptoms of dry eye, the Shirmer I test (ST) might be completed at baseline (V0) and end of study visit (EOS/V2). The evaluation will be performed stratified by study IPs.
次要结局
- Efficacy of Investigational Products used as intended to relieve symptoms of dry eye. The Efficacy will be evaluated by Questionnaire at baseline (V0) and end of study visit (change will be assessed)(Day 0 (baseline visit the IP will be dispensed) and Day 25)
- Evaluation of the safety and tolerability of the Investigational Products by Visual Analogue Scale at the end of study visit(Day 25)
- To assess the efficacy of Investigational Products used as intended to relieve symptoms of dry eye. The efficacy will be evaluated by Tear breakup time test at baseline (V0) and end of study visit (change will be assessed)(Day 0 (baseline visit the IP will be dispensed) and Day 25)
- The patient satisfaction will be evaluated with a 5-points Likert Scale at the end of study visit(Day 25)
