Abstract
The present disclosure relates to a contact lens type dosimeter for measuring a dose distribution of a crystalline lens during radiation therapy, and a method of manufacturing the same. The ocular dosimeter has a contact lens shape and is configured to be worn on an eyeball, which comprises a basic material containing hydrophilic polyurethane, and a radiochromic dye. When the ocular dosimeter is worn on the eyeball, the dosimeter is configured to measure a radiation dose irradiated to a crystalline lens through a variation in color of the ocular dosimeter.
