The lens of the eye is one of the radiosensitive critical organs. We must set up the radiation treatment planning to protect it as little as posible in the reduction of the dosage of the eye, not only benigh tumor but also malignant tumor. In our study, We have evaluated the technique of the radiation in the shallow lesion tumor arround the lens, such as conjunctival tumor. We can reduce the dosage of the lens and cornea 100% to less than 10% using with 2mm lead shield in thick in the treatment 6MeV electron beam. We found this technique is very usefull and effective in clinical radiation treatment planning.
