VEGFA and asthma: Based on our register study, we recommend use of topical non-steroidal anti-inflammatory prophylaxis after cataract surgery, unless the patient has systemic contraindications such as asthma, because topical NSAID (ketorolac) was associated with a remarkably lower incidence rate of Nd:YAG-laser and intravitreal anti-VEGF injection after cataract surgery.
