The European epidemiological study EURALOC aimed to establish a dose response relationship for low dose radiation induced eye lens opacities using interventional cardiologists as the study group. Within the EURALOC project, two dosimetry methodologies were developed serving as the basis for cumulative eye lens dose assessment. Besides being the cornerstone of the epidemiological part of the project, these dosimetry methodologies were also used to develop two calculation tools, ‘mEyeDose’ and ‘mEyeDose_X’ which enable to track, calculate, optimise and analyse eye lens doses in interventional cardiology. mEyeDose was developed as a Mobile Web App and serves as a readily accessible, highly didactic educational tool for interventional cardiologists whereas the user-friendly desktop application mEyeDose_X is designed for radiation protection professionals. Both tools are freely available and can be used for a wide range of purposes such as optimisation of working practices, calculation of cumulative eye lens doses or risk assessment prior to routine eye lens dose monitoring.
