In plain language
In one Pakistani interventional radiology suite, estimated annual eye lens doses were 14.1 mSv for the interventional radiologist and 9.2 mSv for the technologist, below the 20 mSv limit but close enough that regular lens monitoring is warranted.

What it found
The interventional radiologist had the highest estimated annual eye lens dose, followed by the technologist, then assistants and nurses.
Key figures: 14.1 mSv per year (physician); 9.2 mSv per year (technologist)
All estimated eye lens doses were below the International Commission on Radiological Protection (ICRP) annual limit of 20 mSv at the current workload.
Key figures: <20 mSv per year
TACE gave the highest per-procedure eye lens dose.
Key figures: 34 μSv per procedure
The left lens received more dose than the right lens, attributed to positioning and shorter distance to the x-ray source.
Authors warn that rising workload and new procedures could push doses past the limit and recommend regular eye lens monitoring.
Limits to keep in mind
Single-centre study of only six staff over about seven months, with annual doses estimated from a 630-procedure workload; only the abstract highlights and snippets were available, so methods and dosimeter details are unclear.
