Abstract Purpose: To examine the association between the use of topical non-steroidal anti-inflammatory (NSAID) medication, systemic statin therapy, and the incidence rate of two of the most common postsurgical procedures in adult patients undergoing cataract surgery in Finland between January 1, 2010 and December 31, 2016. Methods: This retrospective, nationwide cohort study considered 176,052 cataract operations coded with the International Classification of Disease coding: early adult (H25.0), normal (H25.1), other senile (H25.8), pre-senile (H26.02), or other (related to trauma, other eye disease, or medication). Operations were linked to purchased and reimbursed medications using Anatomical Therapeutic Chemical codes. The incidence rate of intravitreal anti-vascular endothelial growth factor (VEGF) injections, and neodymium-doped yttrium aluminum (Nd:YAG) laser treatments of posterior capsular opacification were evaluated using the Poisson regression model. Results: In our registry cohort, patients with a prescription of topical NSAID (ketorolac) at the time of cataract surgery were less likely treated with intravitreal anti-VEGF injections after surgery (adjusted Poisson regression model IRR 0.3; 95% CI: 0.15–0.60, P = 0.0007), and also had reduced incidence of Nd:YAG laser (0.59, CI: 0.43–0.81, P = 0.0011) treatments. Unlike topical NSAID, the use of systemic statin therapy was not associated with these two most common surgical procedures (RR 1.04, 95% CI: 0.96–1.12, P = 0.33). Conclusion: The use of topical NSAIDs is associated with reduced rates of intravitreal anti-VEGF injections and Nd:YAG laser treatments after cataract surgery. More observational and experimental studies are warranted to confirm possible benefits of topical NSAID administration after cataract surgery.
