- 42 - ABSTRACT This invention relates to a method of con- ducting an operation on the cornea of an eye by the use of an ultraviolet laser such as an excimer laser for correcting an abnormal curve of the cornea of the eye, such as myopia, hyperopia and astigmatism, or for treating opacity of the cornea of the eye, and also relates to an apparatus used in this method. In an operation according to the present invention, the cornea (1) is cooled before, during and after the operation, and at least before and after the operation and also preferably during the operation, a liquid medicine, having such effects as cornea remedy, cure promotion and resolution, is sprinkled or sprayed onto the cornea (1), and a laser beam is irradiated after the excess liquid medicine on the cornea is removed. According to the present invention, thanks to the cooling of the cornea and the effects of the liquid medicine, side effects, caused by a photochemical thermal reaction of the cornea due to the irradiation of the laser beam, can be suppressed as much as possi- ble.
