摘要
A system and method for reshaping the cornea of an eye with a laser that also incorporates a subsequent compensation for residual vision aberrations. A diagnostic unit obtains a pre-op prescription for the eye and predicts an induced refractive shift resulting from laser treatment. Based on this data, a preview lens is selected or manufactured to evaluate the tolerance of a patient to a predicted post-op vision. Then, a laser unit is used to alter the cornea of the eye (i.e. laser treatment) to increase the depth-of-field of the eye. Subsequently, after the laser treatment has been completed, conventional vision correction is provided by spectacles, intraocular lenses or contact lenses. This conventional correction will then compensate for any remaining pre-op aberrations, as well as any residual aberrations in the patient's post-op vision that may have been induced during the laser treatment.
