A process for monitoring and controlling the adjustment of treatment parameters in an ophthalmic treatment device which comprises a radiation source generating at least a treatment beam and, optionally, a target beam and an applicator which is connected with the radiation source via at least one optical element and can be attached to a slip lamp, wherein the following steps are provided: a) the irradiation parameters such as intensity, magnification of the contact lens placed on the eye, radiation dose per unit area, and spot size on the retina are adjusted by the operator at the radiation source; b) first parameters to be adjusted at the applicator are calculated on the basis of patient-related influencing variables such as contact lens magnification and the size of the spot to be realized on the retina, so that a determined spot size and intensity of the treatment beam to be applied can be realized at the treatment site on the retina; and c) parameters adjusted at the applicator are compared with the first parameters by means of a computer and the adjusted parameters are made to coincide with the first parameters representing reference values, and the parameters serving as reference values are realized and maintained constant for the duration of irradiation. An arrangement for carrying out the process employing an ophthalmic treatment device is also disclosed.

[ What is claimed is:] [1.]1. A process for monitoring and controlling the adjustment of treatment parameters in an ophthalmic treatment device, which treats a treatment site of an eye which comprises a radiation source generating at least a treatment beam and, optionally, a target beam, and further comprising an applicator which is connected with the radiation source via at least one optical element, wherein the applicator can be attached to a slit lamp, comprising the steps of:a) adjusting, by the operator patient-dependent irradiation parameters for intended treatment values which set the intensity of a treatment beam, magnification of a contact lens placed on the eye, radiation dose per unit area, and spot size on the retina;b) calculating reference parameters to be used to adjust the applicator on the basis of the patient-dependent irradiation parameters wherein the calculated reference parameters determine the necessary magnification and irradiation output needed at the applicator to produce the patient-dependent irradiation parameters for the intended treatment values at the treatment site on the retina;c) applying the treatment beam to the treatment site of the eye;d) measuring actual parameters for actual magnification and actual irradiation output of the applicator;e) comparing the reference parameters to be used to adjust the applicator with the actual parameters by a computer; andf) adjusting the actual parameters to continuously coincide with the reference parameters thereby realizing and maintaining the patient-dependent irradiation parameters for the intended treatment values as constant for the duration of irradiation.
