In plain language
Pooling eight studies, interventional cardiologists had about three times the rate of posterior lens opacity seen in controls, with no significant difference in cortical or nuclear opacity. This is an association, not proof of cause.

What it found
Posterior lens opacity was about three times more common in interventional cardiologists than in controls.
Key figures: Relative risk (RR)= 3.21, 95% confidence interval (CI) [2.14, 4.83], P < 0.00001
No significant difference in cortical lens opacity between interventional cardiologists and controls.
Key figures: RR= 0.69, 95% CI [0.46, 1.06], P = 0.09
No significant difference in nuclear lens opacity between interventional cardiologists and controls.
Key figures: RR= 0.85, 95% CI [0.71, 1.02], P = 0.08
Eight studies with 2559 subjects, including 1224 exposed interventional cardiologists, were pooled.
Key figures: 8 studies; 2559 subjects; 1224 exposed ICs
Limits to keep in mind
Pools only eight studies; the abstract does not report heterogeneity, study quality, dose data or adjustment for confounders. The catheterization lab staff named in the title are not separately analysed in the abstract.
