| abstract |
A method and arrangements for phacoemulsification are disclosed in which the biological tissue of the eye lens is ablated by the application of energy in the form of pulsed laser radiation and the occurring ablation product is removed from the treatment site by suction. According to the invention, the object is met by a method of the type mentioned above in that the application of energy in the course of the comminution of nucleus parts is influenced by changing the pulse train and/or the intensity of the laser radiation. A change in the pulse train should advantageously be provided in such a way that an interruption in the laser radiation of at least one pulse length is carried out after every series of pulses at a constant pulse frequency. |
