The importance of vision.

Based on a systematic review and meta-analysis of 8 studies, involving 2,559 subjects, both interventional cardiologists (3.21) and cardiac cath lab staff (2.76) had a significantly higher relative risk of posterior lens opacity than the control group. It is essential to provide "best practice" in radiation dose management and lead shielding in the cath lab with the standard "As Low As Reasonably Achievable"! There is a clear need for better data to quantitate the radiation risk and to design innovative strategies to decrease that risk.
