<p>The invention relates to opthalmology and is used for treating keratoconus. The inventive method involves forming one or more radiation areas of different shape, including concentric circles, arcs, parallel lines, cells, grids, spirals or other geometrical figures. In the other variant, the method involves polarising UV radiation and adjusting the depth of the UV radiation action by directing the UV radiation polarisation plane at an angle of 1-180° to the plane of light polarisation by the cornea, thereby using the effect of light polarisation by the cornea. The device for treating keratoconus comprises, positioned on the optical axis common with an UV radiation source, optical focusing elements and a diaphragm. The diaphragm is situated on the optical axis common with the UV radiation source and is made in the form of a mask with alternating transparent and non-transparent in the form of concentric circles, arcs, parallel lines, cells, grids, spirals or other geometrical figures. In the other variant, the device comprises, situated on the optical axis common with the UV radiation source, the optical focusing elements, the diaphragm and a polarisor.</p> |
