Zusammenfassung:The device comprises optically interconnected components such as an ultraviolet pulsed laser operating at a wavelength of 223 nm, a uniform light beam former, a slotted mask with its rotation drive, and a means for forming the image of the slotted mask on a surface of the cornea of the eye. The slotted mask having at least two slots shaped as identical lobes provides in rotation for uniform axysymmetric distribution of ultraviolet radiation over the exposed surface of the cornea. Arranged at the optical outlet of the former are a unit used to monitor energy density of ultraviolet radiation and a microscope. UN DISPOSITIVO DE CORRECCION DE ANOMALIAS DE REFRACCION DEL OJO QUE INCLUYE, OPTICAMENTE ENLAZADOS ENTRE SI, UN LASER DE RADIACION ULTRAVIOLETA DE IMPULSOS CON UNA LONGITUD DE ONDA DE 223 NM, UNA MASCARA RANURADA CON LA TRANSMISION DE SU REVOLUCION, Y UN FORMADOR DE IMAGEN DE LA MASCARA RANURADA EN LA SUPERFICIE DE LA CORNEA DEL OJO. LA MASCARA RANURADA ESTA PROVISTA POR LO MENOS DE DOS RANURAS EN FORMA DE PETALOS IDENTICOS Y DURANTE LA REVOLUCION PROPORCIONA UNA DISTRIBUCION UNIFORME AXIAL SIMETRICA DE LAS RADIACIONES ULTRAVIOLETAS EN LA SUPERFICIE DE LA CORNEA. A LA SALIDA OPTICA DEL FORMADOR DE IMAGEN SE DISPONE EL BLOQUE DE CONTROL DE DENSIDAD DE ENERGIA DE LAS RADIACIONES ULTRAVIOLETAS Y TAMBIEN UN MICROSCOPIO.
