Eye Dryness

Dry eye disease (DED) is a frequent ocular surface disease (OSD) of multifactorial origin, characterised by disruption of tear film homeostasis and associated with ocular discomfort and/or visual disturbance. Cataract surgery, which is one of the most often performed interventions worldwide, can induce or worsen the symptoms of DED. Despite lack of guidelines on DED prophylaxis before cataract surgery in the general population, there is a growing interest in this topic due to the high prevalence of postoperative DED. A recent randomised controlled trial (RCT) with one month follow-up showed that prophylactic low-level light therapy (LLLT) before and after cataract surgery in patients without pre-existing DED significantly improved postoperative tear film stability, as well as reduced ocular discomfort, compared to no prophylaxis. Apart from LLLT, another light-based treatment for DED is intense pulsed light (IPL); the treatments have shown favourable outcomes in the management of DED, both as stand-alone choices or in combination.

The aim of the trial is to compare the safety and efficacy of the moisturizing solution DROP 0.4% with the moisturizing solution AVIZOR EYE DROPS 0.2% PRESERVED in relieving the symptoms of dry eye over one month of use.
