Abstract

A device readable medium for use in controlling a laser vision correction system includes a storage structure having stored therein a pre-programmed first, readable, corrective instruction reference that corresponds to an encoded customized corrective instruction determined by a calculation module external to the medium. The encoded customized corrective instruction is executable by a laser vision correction laser platform for correction of a refractive defect when the corrective instruction reference is properly recognized. A laser vision correction system including the device readable medium is described. A remunerative model relating to the device readable medium is disclosed.
