<p>A spray or delivery device is arranged to dispense a dye into the anterior chamber of an eye for staining a specific ocular structure or tissue (e.g., anterior lens capsule, vitreo-retinal interface). The spray device includes a cannula having a distal end arranged for insertion into the anterior chamber of the eye. The cannula preferably has a dispensing orifice located at a side of the cannula offset from the distal end. In a method for conducting intra-ocular surgery, the delivery device would dispense a dye in a particular fashion so as to control its application to the intended target tissue, thereby limiting delivery of the dye to undesired surrounding tissue structures. Another exemplary embodiment discloses a method of staining an ocular structure, including staining the ocular structure with either indigotindisulfonate, Patent Blue V, Sulphan Blue, tolonium chloride, or Evans Blue.</p> |
