In plain language
In cardiovascular procedures on a biplane system, operator eye dose rate rose when the ceiling shield drifted horizontally behind the physician's head, especially in caudal projections; vertical shield height mattered little. Repositioning the shield after angle changes may lower lens dose.

What it found
Horizontal displacement of the ceiling-suspended shield was strongly negatively correlated with operator eye dose rate during fluoroscopy and cine.
Key figures: R = -0.656 to -0.829, p < 0.01 (fluoroscopy); R = -0.538, p < 0.01 (cine)
Eye dose rate increased significantly when the shield was positioned posterior to the physician's head.
Dose rate differed by beam angulation, with higher values in caudal projections.
Key figures: p < 0.001
Vertical shield displacement had weak or no correlation with eye dose rate within typical use.
Limits to keep in mind
Abstract only; number of procedures and physicians, country and absolute dose values are not reported. Correlational dosimetry data near the eye, not lens dose under eyewear or health outcomes.
