During radiation therapy with electron beam to eyelid, we must keep the minimal dose on eyeball as possible. especially in the treatment of Sebaceous gland carcinoma, Squamouse cell ca., and basal cell ca. of eyelid and low grade MALToma etc. But if radiation field covered the upper & lower eyelid, it makes a cataract on lens of treated eye, in late complications. Now we reports the advantages of Tungsten eyeball shielding block compare to previously used lead block. with BOLX-I material, we made a eyeball model and measured the absorbed dose of 6MeV & 9MeV electron hem at 6 point of eyeball model with TLD chip. And compare the absorbed dose to previously lead block and other types of Tungsten eyeball shielding block.
