Patent ID: 8430862

Claim:
A method for administering a pharmacological agent formulation to a subconjunctival compartment of an eye, comprising the steps of: providing a subconjunctival agent delivery apparatus containing the pharmacological agent formulation in an internal formulation chamber, said agent delivery apparatus including needleless injector means that is in communication with said internal formulation chamber, said needleless injector means including a first transfer mechanism having an integral nozzle member-guide platform assembly, said nozzle member-guide platform assembly comprising a first nozzle member and a deformable guide platform that is adapted to substantially conform to a first surface of a first eye structure and position said subconjunctival agent delivery apparatus on said eye structure when in an engagement position thereon, and force generating means that is adapted to generate sufficient force to expel the pharmacological agent formulation from said agent delivery apparatus and into and through an eye structure; positioning said subconjunctival agent delivery apparatus on said first surface of said first eye structure; and activating said subconjunctival agent delivery apparatus, whereby said pharmacological agent formulation is expelled from said subconjunctival agent delivery apparatus and delivered to said first surface of said first eye structure with a delivery pressure in the range of approximately 100-1000 psi and, whereby a first volume of said pharmacological agent formulation is administered to the subconjunctival compartment of the eye.
