Silver-Plated Eye Shield, SMALL.

The Silver-Plated Lead Eye Shields protect the patient’s lens and cornea during radiation therapy treatments. The eye shields are available in four different sizes to fit all sizes of patients.

The small and medium solid lead eye shields fit under the eyelid to protect the lens, while permitting irradiation to the entire thickness and width of the eyelids in the treatment of superficial basal cell carcinomas of the skin.  Large solid lead eye shields are used when areas surrounding the eyes require irradiation, in which case, the shields are placed over the lid.  When only a portion of the eyelid requires irradiation, an extra large shield with a window is properly placed over the eyelid.

These Eye Shields are fabricated of virgin lead and are silver-plated. The lead permits less than 1% transmission of the radiation intensity at 120 kVp (3 mm Al HVL).

Using a soft contact lens (937-700) or coating the eye shield with dental wax (933-122) will give a smooth surface on the eye to prevent scratching or irritation to the eye.

These eye shields must be handled with care. Dents, scratches or silver flaking from improper handling or cleaning are not repairable or covered under the warranty.

Always consult the Radiation Physicist when using eye shields in electrons. 6MeV electrons have had a reported 16-25% transmission factor. Electron backscatter from lead eye shields has been reported to be 40% to 50%.
