Zusammenfassung: | A method for preparing an apparatus for customizing corneal corrections comprising superposing a reference field (grid) on the anterior surface of the cornea of an eye to divide the corneal surface into reference areas. Said reference areas are typically suitable for corresponding with a refractive power map of the cornea and preferably for directing an incising laser beam through an individual reference area to a focal spot, selectively moving the focal spot along the laser beam path to photoalter a predetermined volume of stromal tissue and redirecting the beam and moving the focal spot through another said reference area until the required corneal correction is achieved. |
