Abstract: Sistema de corrección óptica (10) para corregir defectos visuales de un ojo (120), el sistema (10) de corrección óptica comprende: analizador de frente de onda (26) para determinar una diferencia de trayectoria óptica entre un frente de onda de referencia (131) y un frente de onda con aberraciones (130) del ojo (120), un conversor (40) para proporcionar una corrección óptica de cada ojo basada en la diferencia de camino óptico e índices de refracción del medio (126) a través del que pasa el frente de onda con aberraciones (130), caracterizado porque: el sistema de corrección óptica comprende además: un tren óptico en la trayectoria del frente de onda con aberraciones que comprende una primera lente mantenida en una primera posición fija y una segunda lente para cambiar la longitud de la trayectoria óptica entre dicha primera y segunda lentes.

Abstract: A system and method for objective measurement and correction of focusing optical systems comprising optics disposed in the path of the beam (18) which directs the beam through the focusing optical system, e.g., and eye (120) and focuses the beam at its rear portion (122). The beam is diffusely reflected back and a wavefront analyzer (26) is disposed in the path of the wavefront projected from the optics and calculates the distortions as an estimate of aberrations of the focusing optical system.
