“…Under the guidance of the angiography machine, the surgeon will send the catheter to the desired position according to his own knowledge of human anatomy. Under the development of the angiography agent, the vascular condition of the lesion can be determined, and the lesion can be treated directly in the blood vessel [3], including arterial embolization and angioplasty. Commonly used body surface puncture points include radial artery, femoral artery, femoral vein, subclavian artery, subclavian vein, carotid artery, and vein.…”

The aim of this study was to estimate the exposure dose level of ocular corpuscles during the common interventional procedures of interventional radiology workers. This article retrospectively analyzed the general instruments and equipment of interventional therapy, the general methods and steps of interventional therapy, and the influence of X-ray of interventional surgery. The related contents of eye protection for interventional radiology workers were summarized. This study found that there was a significant linear correlation between the equivalent dose of lens and the exposure time. The tube voltage, tube current, and the size of fluoroscopic field of vision also have an impact on the radiation of workers during surgical exposure. Interventional surgery is difficult and easy. The exposure time of difficult surgery is relatively long, so the dose received by interventional staff is large. The intervention staff should improve their professional knowledge, be proficient in the operation technology, and try to reduce the exposure without affecting the diagnosis and treatment effect. During the intervention operation, the eye substance of the operator is exposed to a certain dose of radiation, and the wearing rate of protective lead glasses of the intervention staff is very low. Therefore, we must pay attention to the protection of the eyes, strengthen the protection management, and reduce the exposure dose of the intervention staff as much as possible.
