Radiation therapy with low energy electrons is particularly beneficial for treating ocular lymphomas involving the conjunctiva. The anterior lens, being a highly radiosensitive structure, has a dose tolerance range of 10 to 18 Gy. Lens shielding used in conjunction with electron beam therapy can reduce the risk of high-grade cataracts following treatment with prescriptive doses of 25 to 30 Gy. Bolus may be required in some clinical situations to ensure superficial tumour coverage. This work evaluates the effects of a suspended eye shield, placement of bolus, and varying electron energies. A cataract is a cloudy area in the lens of your eye. Cataracts are very common as you get older. In fact, more than half of all Americans age 80 or older either have cataracts or have had surgery to get rid of cataracts. At first, you may not notice that you have a cataract. But over time, cataracts can make your vision blurry, hazy, or less colourful. You may have trouble reading or doing other everyday activities. The good news is that surgery can get rid of cataracts. Cataract surgery is safe and corrects vision problems caused by cataracts.
