The purpose of this exhibit is: To provide a comprehensive overview of radiation cataractogenesis in interventional radiology To review the operator lens doses seen in common IR procedures and the data linking cataract development with interventional work To describe optimal lens protection for the IR physician and strengths and weaknesses of each protection technique

Background ICRP threshold guidelines, data motivating the 2011 threshold change [Figure 1] Mechanistic basis of radiation cataract, including the role of radiation genotoxicity Assessment of the stochastic versus deterministic nature of radiation cataractogenesis [Figure 2] Data linking radiation exposure and cataract development in interventional physicians [Figure 3] Multiple studies showing a statistically significant increase in cataract risk in interventionists Factors modulating this risk Lens dose in common IR procedures [Figure 4] Physician lens dose in TIPS, CT guided biopsy and drainage, vertebroplasty, chemoembolization, neurointerventional techniques, etc. Critical analysis of lens protection strategies [Figure 5] Leaded eyeglasses Ceiling-suspended shields Complex commercial shielding devices Real-time dosimetry Radiation education
