Abstract

A method and business architecture for providing vision correction to a patient involves obtaining wavefront aberration measurement information and, optionally, patient history data, ordering data, dispensing data, billing data, and other information, from the patient; transmitting the various data to respective appropriate platforms, e.g., transmitting the wavefront aberration information to a custom lens supply platform; producing a custom lens for the patient; and delivering a custom lens to the patient in a personalized manner. The method further involves fitting and measurement processes including in-situ lens shaping and custom manufacture of contact lenses, IOLs, inlays or onlays by laser ablation, lathing, casting/molding and machining. Business architectures according to the invention include segregating vision correction method steps into contractual, revenue generating business transactions.
