A device for treating bodily substances, in particular for intraocular cataract surgery, said device comprising a laser beam source, for example, an erbium YAG laser, which produces pulsed laser radiation at wavelengths in the infrared range. A control device comprises a first arrangement ( 38, 48 ) by means of which an acceptable range for the pulse energy and/or pulse length and/or pulse frequency can be predetermined before an operation, and a second arrangement ( 34, 36, 40, 42 ) by means of which the pulse energy and/or pulse length and/or pulse frequency can be adjusted to a given value or values within the predetermined range during the operation. |
