More than 1 million percutaneous cardiac intervention (PCI) procedures are performed annually in the United States,1 resulting in some reduction of cardiovascular mortality.2 Because the correlation between occupational radiation exposure and excess risk of cataract formation in medical staff is well documented,3- 5 ocular protection from radiation (ie, routine use of lead eye glasses) is recommended for interventionists. However, the risk of radiation cataract for patients undergoing PCI procedures has not drawn much attention, and there are no current guidelines for patient eye protection. Hence, we conducted this study to evaluate the risk of cataract in the population undergoing PCI procedures.
