COMS-type gold seed carriers typically can be ordered in 6 sizes in 10-20 mm diameters (Trachsel DentalStudios, 1-507-288-2362).
Rice-sized radioactive seeds are purchased and glued into the eye-plaque or seed carrier.
The gold of the eye-plaque will block more than 99% of the radiation to the back and sides, creating a directional source. The active surface (facing us) is sewn onto the eye beneath the base of the intraocular tumor.
