Abstract[English]
A method for treating near-retina floaters includes dilating a pupil of an eye of a patient to at least 6.6 millimeters (mm). While the pupil is dilated to at least 6.6 mm, the method further includes emitting, by an optical delivery system, a plurality of pulses from a treatment laser into the eye of the patient, each pulse of the plurality of pulses having a diameter upon passing through the pupil that substantially fills the pupil and having a focus within 3 mm of a retina of the eye of the patient. Pulses may pass through adaptive optics that may be adjusted based on light emitted from the eye, such as two-photon fluorescence or second harmonic radiation, in order to reduce spot size at the focus.[French]
Un procédé de traitement de flotteurs proche de la rétine comprend la dilatation d'une pupille d'un œil d'un patient à au moins 6,6 millimètres (mm). Pendant que la pupille est dilatée à au moins 6,6 mm, le procédé consiste en outre à émettre, par un système de distribution optique, une pluralité d'impulsions provenant d'un laser de traitement dans l'œil du patient, chaque impulsion de la pluralité d'impulsions présentant un diamètre lors du passage à travers la pupille qui remplit sensiblement la pupille et présentant un foyer à l'intérieur de 3 mm d'une rétine de l'œil du patient. Des impulsions peuvent passer à travers une optique adaptative qui peut être ajustée sur la base de la lumière émise par l'œil, telle qu'une fluorescence à deux photons ou un rayonnement de seconde harmonique, afin de réduire la taille de point au foyer.
