[ What is claimed is:] [1.]1. A method of vision correction comprising:directing laser energy to a mask to provide a modulated laser beam having different energy levels at different locations across the modulated laser beam; anddirecting the modulated laser beam to a cornea of a patient to ablate a region of the cornea to different degrees to provide the cornea with progressive vision correction powers.
