    • The invention relates to ophthalmology. The inventive method for intracapsular destruction of a cataract-altered crystalline lens consists in exposing said crystalline to the action of pulse-periodic laser radiation having a bell-shaped or trapezoidal pulse within a spectral range of 1300-2400 nm. Said radiation is carried out from the distal end of an optic guide associated with the simultaneous irrigation and aspiration of the broken crystalline particles. Said laser radiation has the following parameters: the radiation pulse duration ranges from 0.1 to 10.0 mks, the duration of the leading edge of radiation pulses ranges from 0.01 to 0.15 mks, the energy of radiation pulses ranges from 0.5 to 20.0 MDI, radiation pulse-repetition frequency ranges from 0.5 to 20.0 kHz, the optical quality of the beam at the input of a M2 laser radiator ranges from 1 to 5.

    • A laser light irradiator which can comply both treatments of non−thermal reaction and photothermal reaction by switching the output of laser light with fluctuations in the excitation current of a semiconductor laser diode. A reference signal for a CPU 41 to decide the output level of a semiconductor laser diode (35) in accordance with the on/off operations of an output switch (S2) is output via an I/O port (44) and a D/A converter (471) and amplified by an amplifier (472) to generate a reference voltage of laser output. Since a semiconductor laser diode (35) has a structure of extracting laser output from both sides of the device, one laser output is sensed by a photodiode (473), and its sensed voltage is amplified by the amplifier (474) to generate a monitor voltage. The reference voltage and monitor voltage are input into a differential amplifier (475) and amplified by an amplifier (476) to impress an operating current which excites laser oscillation of a set output level on the semiconductor laser diode (35).

    • The aim of the invention is to provide technical measures for creating a fistula toward the Schlemm's canal with the goal of minimizing the scarring stimulus such that the duration in which the fistula can perform its function is maximized. To this end, the Schlemm's canal is subjected to an ab interno puncturing using a Q-switched erbium laser (1) having a pulse length of distinctly less than 200 ns. A preoperative filling of the Schlemm's canal with a biocompatible fluorochrome, which can be excited using a pilot laser (7), serves to prevent a complete perforation. The fluorescence detected via the active waveguide (4) serves as a switch-off criterion for the active radiation with which only the Schlemm's canal is opened. According to the invention, the scarring stimulus is further reduced by the fluorochrome that acts as a photosensitizer for inducing a non-traumatic cell death.
