The eyes that a kind of ophthalmic indicia equipment is used to mark patient are provided here. Equipment includes: handle (12) and a tip (14) with computing unit, and the first part of computing unit stretches out from the tip and exposure. Computing unit is electrically conductive to generate resistance-type heat using by electric current therein. Power supply (42) is associated with the equipment, and is electrically connected with the computing unit. Power supply and computing unit are configured so that first parts temperature range of computing unit is 250 °F -450 °F. Advantageously, theme invention provides the equipment of relatively low cost a kind of to mark the eyes of patient, and compared to generating traumatic smaller label on the eyes of patient for the higher electrocautery equipment of temperature.
