Abstract: An apparatus for treating body tissue, particularly for intraocular cataract surgery, comprising a laser beam source such as an erbium YAG laser that produces pulsed laser radiation at a wavelength in the infrared range. The controller is configured to determine an acceptable pulse energy and / or pulse length and / or pulse frequency before surgery (38, 48), and to control the pulse energy and / or pulse length and / or pulse frequency. A second device (34, 36, 40, 42) is provided, which can sometimes be adjusted to one or more predetermined values within a predetermined range. |
