Abstract

Cataract surgery is the most frequently performed elective surgery worldwide. Although considered a safe procedure, potentially sight-threatening adverse events are possible. Among these, post-surgical inflammation and infections are the most relevant. Anti-inflammatory drugs, such as corticosteroids, and topical antibiotics are the pillars for the treatment of inflammation and for the prevention of infections. However, uncertainties remain regarding the duration of both topical antibiotic prophylaxis and corticosteroid treatment. LEADER7, a recent international clinical study conducted with the new fixed combination of levofloxacin and dexamethasone eye drops in patients undergoing uncomplicated cataract surgery, found that 1-week topical antibiotic prophylaxis is just as effective as the 2-week course commonly used in clinical practice. The study also showed that treatment for 1 week with dexamethasone results in complete resolution of inflammatory signs and symptoms in over 85% of patients, for whom further prolongation of corticosteroid treatment is, therefore, not necessary. This new treatment strategy can represent a significant step forward to reduce the unjustified use of prophylactic antibiotics after cataract surgery, limiting the emergence of bacterial resistance, as well as representing an opportunity to optimize the use and safety of the corticosteroid treatment.
