Patent ID: 8535333

Claim:
A method of using a delivery system for implantation of a device into an eye in the absence of a lens or other imaging system, the method comprising: mounting an implant on a delivery device comprising a guidewire having a sheath coupled to the guidewire, wherein the guidewire comprises a first metering system at a distal end of the guidewire and the sheath comprises a second metering system at a distal end of the sheath, the first and second metering systems having corresponding graduated markings; inserting the implant on the delivery device into an anterior chamber through an incision in a cornea; advancing the implant on the delivery device through a transparent zone of the anterior chamber toward an opaque zone of the anterior chamber; seating a distal end of the guidewire at eye tissue where resistance is felt; reading through the transparent zone a first graduated marking of the first metering system, wherein the first graduated marking is aligned with an edge between the transparent zone and the opaque zone; advancing the implant on the guidewire into the eye tissue beyond where resistance is felt; and reading through the transparent zone a second graduated marking on the second metering system, wherein the second graduated marking is aligned with the edge between the transparent zone and the opaque zone.
