Abstract
Dispositivo para modificar la forma de la córnea. Por medio de este dispositivo se consigue cambiar plásticamente la forma de la córnea mediante la aplicación del vacío. El dispositivo consiste en una cámara de vacío (1) con aperturas (3) que está conectada a una bomba de vacío (2). Colocando el dispositivo en la superficie de la córnea y después haciendo el vacío, se consigue una deformación plástica de la zona de la córnea por debajo de las aperturas. El resultado es que la curvatura de la córnea y la refracción del ojo son modificadas.Una córnea mas plana reduce o corrige la miopía. Aplicaciones de este invento incluyen la corrección de todos los errores de refracción: miopía, hipermetropía y astigmatismo.Device to modify the shape of the cornea. By means of this device it is possible to plastically change the shape of the cornea by applying a vacuum. The device consists of a vacuum chamber (1) with openings (3) that is connected to a vacuum pump (2). By placing the device on the surface of the cornea and then vacuuming, a plastic deformation of the cornea area below the openings is achieved. The result is that the curvature of the cornea and the refraction of the eye are altered. A flatter cornea reduces or corrects myopia. Applications of this invention include correction of all refractive errors: myopia, hyperopia, and astigmatism.
