A protective film ( 1 ) for protecting a cornea against direct contact with a laser applicator has a treatment area ( 2 ) of a first film thickness and a profile region ( 3 ) that is raised with reference to the treatment area ( 2 ) and whose film thickness is configured to be greater than the first film thickness. In the state in which the protective film ( 1 ) is arranged between the cornea and applied laser applicator, the treatment area ( 2 ) positions a first part of the cornea, which part is to be treated, in a focal region of the laser applicator, and the profile region ( 3 ) positions a second part of the cornea, which part is not to be treated, outside the focal region. The raised profile region ( 3 ) presses the eye tissue region not to be treated out of the cutting plane of the laser applicator such that the focused laser pulses cannot reach this tissue region, and therefore cannot inadvertently impair and damage it.
