Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis
Acta Ophthalmologica, EarlyView.Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...
