AAO: Prior Intravitreal Injections Increase Risk for Cataract Surgery Complications

A history of multiple past intravitreal injections (IVIs) poses a risk for certain future cataract surgery complications, according to a study presented at the annual meeting of the American Academy of Ophthalmology, held from Oct. 18 to 21 in Chicago.

Winnie Yu, from the University of Toronto, and colleagues used physician billing and diagnostic data from the Ontario Health Insurance Plan to identify 163,663 adults (aged 20 years and older) with retinal conditions who had undergone cataract surgery between 2009 and 2018, of whom 3,243 received anti-vascular endothelial growth factor (VEGF) eye injections prior to surgery. Occurrence of 10 visually significant complication events due to cataract surgery were compared among patients who had a history of IVIs and those who did not.
