摘要： The present invention relates to devices used in ophthalmology for laser therapy, and may be used for stimulating the ciliary muscle. This invention can also be used for reducing the risks of unwanted side-effects by lowering the vision tension as the patient keeps looking with both eyes in reference directions that correspond to the position and the convergence of the visual axes of the eyes. The device of the present invention comprises two optical units (1, 1') each having up to two laser emitters (2) mounted therein, wherein said emitters include shaping optics (3) for applying a trans-spectral action using laser radiation on a corresponding section in the prelimbal region of the eye. A light source (4) of the LED type is mounted on the optical axis of each unit. The light source generates a luminous mark in the patient's field of vision so that the patient keeps looking in the reference directions (5, 5') during a laser therapy session. In order to modify the angle between the reference directions (5, 5'), the optical units (1, 1') are mounted on platforms (6) so as to be capable of rotation about their own axes in the azimuthal plane, and so that they can be secured in a desired position. The platforms (6) are further mounted on a guide (7) so as to be capable of longitudinal displacement.

摘要： The present invention may be used in the laser stimulation of the ciliary muscle for improving the adaptation capacity of the eye, for increasing the visual capacity, for reducing discomfort during the therapy process and for applying a combined action using a laser beam, i.e. a transscleral action on the ciliary body and on the central region of the retina. The device of the present invention comprises an optical unit (1) including a plurality of laser emitters (2) with shaping optics (3) and a local reducer (4) of the field of vision which is made in the shape of a diaphragm and defines a vision channel (5) representing the direction in which the patient is looking. The diaphragm (4) is arranged on a same axis (6) together with the inlet aperture (7). The optical unit (1) may further comprise a visible laser-beam source (8) which is optically connected through a semi-transparent mirror (9) to the vision channel (5) so as to apply an action on the central region of the retina. The transmission ratio of the mirror (9) is selected so that the patient is not prevented from observing a distant object through the outlet aperture (10) of the unit (1). It is further possible to include a diffused dispersion structure (11) allowing the patient to observe a speckle diagram formed by the laser beam emitted from the source (8).
