Brief summary: Dry eye disease (DED) is a highly prevalent ocular condition and induces a significant burden to the affected patients. Regardless of the underlying etiology, DED is associated with increased inflammation of the entire ocular surface including the adnexa, conjunctiva and cornea. As such, there is evidence from in vitro, animal and clinical studies that this inflammatory response of the ocular surface plays a pathophysiological key role in the development of DED. The Dry Eye Workshop 2007 (DEWS) therefore suggests the use of anti-inflammatory drugs such as corticosteroids, cyclosporine or others when topical lubricants alone are not sufficient. Recently, Softacort® eye drops containing 0.335% hydrocortisone have gained marketing authorization for the treatment of ocular surface inflammation. This formulation offers several advantages that make them potentially interesting for the treatment of DED. First, the formulation is preservative-free, which is of special importance in patients with DED, since it has been shown that preservatives are detrimental for the ocular surface. Further, hydrocortisone has the advantage that in comparison to other glucocorticoid derivatives, it features poor solubility. This means that corneal penetration is low, which is a desired effect in the treatment of ocular surface inflammation. Because of the poor penetration through thecornea, elevation of intraocular pressure and cataract formation, which are common side effect of corticosteroid treatment, have not been observed with Softacort® to date, also favoring the use of this agent in DED. The aim of the present study is to investigate whether treatment with Softacort® improves ocular surface inflammation as well as clinical signs and symptoms associated with DED in patients who are already taking topical lubricants for at least three months.
