Claim Text:
1. A method for simultaneously ablating and functionalizing a portion of a polymeric ophthalmic substrate surface, comprising the following steps: Applying a CO2 particle spray against an unreacted portion of the polymeric ophthalmic substrate surface; and Simultaneously projecting at least one source of ionizing-heating radiation into said CO2 particle spray flowing against said unreacted portion of the polymeric ophthalmic substrate surface, thus intersecting and mixing together to form an instantaneous surface treatment composition of ionizing-heating radiation and CO2 particle spray flowing against the polymeric ophthalmic substrate surface, and to form and remove a reacted portion of the polymeric ophthalmic substrate surface; and the at least one source of ionizing-heating radiation is Blown Ion Plasma or Corona Plasma.
