| 摘要 | A therapeutic laser with a source of pulsed electromagnetic radiation, a control device for controlling the intensity and/or the duration of the therapeutic laser applied to the tissue, and a detection device for detecting optoacoustic signals triggered by irradiating the living tissue with the pulsed electromagnetic radiation. The therapeutic laser is characterized by an evaluation device that acts on the control device and is used for calculating a degree of quality B(t) from the optoacoustic signals detected by the detection device for individual laser pulses applied to a predetermined laser spot and determining a fit function f(t) at a predetermined point in time Δt1, the fit function f(t) approximating the mean curve of B(t) for 0≦t≦Δt1. The intensity and/or the irradiation time of the therapeutic laser is defined by the parameters for the predetermined laser spot, the parameters being determined for the fit function f(t). | ||

| 主权项 | 1. Apparatus for treating a retina of a living eye with a laser, comprising a therapeutic laser with a source of pulsed electromagnetic radiation, a control device for controlling the intensity applied to the tissue and/or the irradiation duration of the therapeutic laser, and a detection device for detecting optoacoustic signals triggered by irradiating the living tissue with the pulsed electromagnetic radiation, wherein an evaluation device connected to the control device is used for calculating an evaluation measure B(t) for individual laser pulses on the basis of the optoacoustic signals detected by the detection device, and for determining a fit function f(t) at a predetermined point in time Δt1, that fit function f(t) approximating the mean curve of B(t) for 0≦t≦Δt1 with a slope different from zero, wherein 0≦t≦Δt1 is a startup phase in which as yet no tissue changes on the retina occur, the laser intensity and/or the irradiation time of the therapeutic laser being defined by the parameters determined for the fit function f(t). | ||
