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 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 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 substrate surface, and to form and remove a reacted portion of the substrate surface.

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; andSimultaneously 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. 2. The method of claim 1, wherein the CO2 particle spray is a CO2 Composite Spray. 3. The method of claim 2, wherein the CO2 Composite Spray is a composition of solid phase carbon dioxide particles, having variable particle size and concentration, entrained in a temperature-controlled, pressure-controlled, and flow-controlled propellant comprising a clean inert gas. 4. The method of claim 1, wherein said at least one source of ionizing-heating radiation is a UV Laser, NIR Laser, IR Laser, RF Ablation, Pulsed UV Light, IR Light, Excimer Laser, Semiconductor Laser, Diode Laser, Fiber Laser, Nd:YAG Laser, LED Laser and CO2 Laser. 5. The method of claim 1, wherein the polymeric ophthalmic substrate surfaces comprise polymers, plastics, composites, polyester, polyethylene, polycarbonate, acrylics, polymethylmethacrylate, polyureaurethane, polysulfone, thiourea, polyetheretherketone, polypropylene, polyamide, polyimide, polyamide imide, polyester imide and silicones. 6. The method of claim 3, wherein the CO2 Composite Spray controls surface temperature by impinging a composition of CO2 solid particles and particle sizes entrained in the temperature-regulated and pressure-regulated propellant gas against said same surface portion. 7. The method of claim 3, wherein the propellant comprises air, nitrogen, oxygen, ozonated air, carbon dioxide, argon, or helium gas. 8. The method of claim 2, wherein the CO2 Composite Spray contains additives comprising silanes, siloxanes, fluorinates, amines or ozone or other organic and inorganic compounds, which provide beneficial surface chemistry during surface plasma reactions. 9. The method of claim 1, wherein the simultaneous ablation and functionalization is between 0.1 mm/sec and 300 mm/sec. 10. The method of claim 1, wherein the simultaneous ablation and functionalization is between 10 mm/sec and 200 mm/sec. 11. A method for simultaneously ablating and functionalizing a portion of a polymeric ophthalmic substrate surface, comprising the following steps: Applying a CO2 Composite Spray against an unreacted portion of the polymeric ophthalmic substrate surface; andSimultaneously projecting at least one source of ionizing-heating radiation into said CO2 Composite 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 Composite 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. 12. The method of claim 11, wherein the CO2 Composite Spray is a composition of solid phase carbon dioxide particles, having variable particle size and concentration, entrained in a temperature-controlled, pressure-controlled, and flow-controlled propellant comprising a clean inert gas. 13. The method of claim 11, wherein said at least one source of ionizing-heating radiation is a UV Laser, NIR Laser, IR Laser, RF Ablation, Pulsed UV Light, IR Light, Excimer Laser, Semiconductor Laser, Diode Laser, Fiber Laser, Nd:YAG Laser, LED Laser and CO2 Laser. 14. The method of claim 11, wherein the polymeric ophthalmic substrate surfaces comprise polymers, plastics, composites, polyester, polyethylene, polycarbonate, acrylics, polymethylmethacrylate, polyureaurethane, polysulfone, thiourea, polyetheretherketone, polypropylene, polyamide, polyimide, polyamide imide, polyester imide and silicones. 15. The method of claim 11, wherein the CO2 Composite Spray controls surface temperature by impinging a composition of CO2 solid particles and particle sizes entrained in the temperature-regulated and pressure-regulated propellant gas against said same surface portion. 16. The method of claim 12, wherein the propellant comprises air, nitrogen, oxygen, ozonated air, carbon dioxide, argon, or helium gas. 17. The method of claim 11, wherein the CO2 Composite Spray wherein the CO2 Composite Spray contains additives comprising silanes, siloxanes, fluorinates, amines or ozone or other organic and inorganic compounds, which provide beneficial surface chemistry during surface plasma reactions. 18. The method of claim 11, wherein the simultaneous ablation and functionalization is between 0.1 mm/sec and 300 mm/sec. 19. The method of claim 11, wherein the simultaneous ablation and functionalization is between 10 mm/sec and 200 mm/sec.
