ABSTRACT:
A method and device for reshaping cornea 12 wherein radially orientated microintubation channels 32 are surgically created in corneal stroma 30 with surgical microinstrumentation after which corneal shaping devices 34 are inserted into said microintubation channels. Said microintubation channels extend radially from peri-limbal tissue towards the center of said cornea, but not to the very center of said cornea. Said corneal shaping devices place stress on the dome of said cornea and alter corneal topography in a manner that allows for correction of distance vision, near vision, and astigmatism.
