The contribution of interventional cardiologists and electrophysiologists will:

  1. provide a scientific basis for the determination of the low-dose threshold for lens opacities,
  2. have an impact on the improvement of radiation protection and dose reduction procedures for medical staff in the clinical environment.

With the revised lower dose threshold, radiation effect on the eye lens has become one of the major concerns in relation to occupational, medical and public exposures. The European EURALOC study aims at clarifying the dose-response relationship and in the meantime provides some practical tools to reduce occupational exposure of medical staff.

Twelve European countries will participate to the European joint epidemiological project EURALOC by recruiting interventional cardiologists. A strength of the European cohort is the use of a common protocol, ensuring the comparability of information, regarding confounders for cataract and occupational history for retrospective dose assessment and the possibility to pool all data in one large European cohort for joined analysis. A European cohort of about 440 interventional cardiologists and electrophysiologists and an unexposed group of about 285 persons are foreseen.
