<p>The invention concerns a laser photocoagulator comprising a laser emitting at a wavelength within the ICG absorption spectrum and provided with focusing means and a programmed or controlled module powering the laser such that the mean fluence (F) at the focus starting from an initial time varies according to an increasing function in time not varying at any time by more than 10 % of an increasing monoexponential corresponding to formula F = Fo(1-e?-t/τ¿) wherein F is the initial fluence and τ is a time constant ranging between 3 and 5 mn.</p> |
