  • Apparatus for corneal surgery
    Patent number: 6607521
    Abstract: An apparatus for corneal surgery to correct a refractive error by ablating corneal tissue with a laser beam emitted from a laser source and delivered onto a cornea of a patient's eye with a light delivering optical system, the apparatus comprising an irradiation area limiting device for limiting an irradiation area of the laser beam and for varying the irradiation area, a first control device for controlling the irradiation area limiting device so as to reduce an ablation amount as the laser beam irradiates further away from a flattest meridian of astigmatism whereby effecting astigmatic correction, a second control device for controlling the irradiation area limiting device so as to increase an ablation amount as the laser beam irradiates further away from a steepest meridian of astigmatism whereby effecting astigmatic correction, and an arithmetic device for dividing a refractive power required for astigmatic correction into halves approximately-equally so that an approximately half of the astigmatic c
