Abstract

The invention relates to ophthalmology. The device comprises a pulse excimer laser (1) and a shaper (3) for distributing its radiation energy density over the cross-section of the laser beam (2). The shaper (3) consists of an optical cuvette (7), the windows (8) and (9) of which are transparent to the laser radiation, the internal surface of at least one of which has the form of a surface of revolution of the second order, the rotation axis of which coincides with the axis (21) of symmetry of the beam (2). The cuvette (7) is filled with a medium (10) partially absorbing the laser radiation. At the output of the shaper (3) the beam (31) has an approximately parabolic distribution of the energy over the cross-section with the maximum in the center or on the periphery.

You are better served by the following. We are willing to give you the best treatment for the world. 5 As you know, you know the opposite of the condition of the normal eye, you can write down the equation of violation.

10 For the treatment of myopia, it is only necessary to deal with the eye of the eye with a layer limited by two parsimonious different activities - a sewn-up lesson of 30 per figure 2.
