In plain language
Among interventional cardiologists, nurses and technicians examined at a cardiology congress, radiation-type posterior lens changes were found in 41-50%, compared with under 10% of unexposed controls. Most affected staff had worked for years without eye protection.

What it found
Posterior subcapsular lens changes characteristic of radiation were found in half of interventional cardiologists and 41% of nurses and technicians, versus under 10% of unexposed controls.
Key figures: 50% of interventional cardiologists; 41% of nurses and technicians; <10% of controls
Estimated cumulative eye doses varied widely among exposed staff.
Key figures: 0.1-18.9 Sv
Most lens injuries occurred after several years of work without eye protection.
Authors call for improved radiation safety training, eye protection use and occupational dosimetry.
Limits to keep in mind
Convenience sample of congress attendees with lens doses estimated retrospectively from questionnaires and lab measurements rather than personal dosimetry; control group size and country not stated in the abstract.
