PSAT is used to facilitate the delivery of sterile ophthalmic solutions to the back of the eye. A simple pars plana incision is made to expose the suprachoroidal or subretinal space. The iTrack™ 370P microcatheter is inserted and advanced to the target area. Catheter location is confirmed by observing the illuminated tip through the pupillary aperture, and upon arrival at the specific site, a solution can be delivered. Surgeon control is enhanced during the PSAT via the 5 mm increment depth markings on the distal end of the iTrack™ 370P. These precise markings provide a depth reference, so that microcatheter position and control can be maintained during initial insertion and prior to rotation of the eye for pupillary aperture visualization.
