The iScience Surgical Ophthalmic Viscoinjector is a manually operated device for precision delivery of small amounts of viscous fluid such as a sterile viscoelastic solution pre-packaged in a cartridge, for example Healon, HealonGV and Healon5 manufactured by Advanced Medical Optics Inc., and Ocucoat manufactured by Bausch and Lomb.

The iScience Surgical Ophthalmic Viscolnjector consists of a holder for a viscoelastic The loolorios bargreates a manually operated screw driven plunger. For use, a cantridge of viscoelastic solution is placed into the body of the Ophthalmic Viscolnjector. A needle inside the Ophthalmic Viscolnjector pierces the septum of the viscoelastic cartridge as it is seated within the body cavity. The cap from the Ophthalmic Cannage as it is connected to the body to secure the cartridge of viscoelastic solution inside the Viscolnjector. The thumbwheel is rotated clockwise thereby advancing the screw driven plunger to deliver viscoelastic solution. The end of the screw has a bushing that contacts the stopper in the viscoelastic cartridge. As the screw is advanced at a controlled rate the stopper displaces fluid out through the needle that has pierced the septum. The opposite, blunt end of the needle is embedded in a male Luer lock connector. This connector may be mated to a female Luer connector and the viscoelastic solution delivered. Markings on the thumbwheel, cap, and body of the Viscolnjector are provided to assist in determining the number of complete or partial thumbwheel rotations and thus relate to the amount of fluid delivered.

The iScience Surgical Ophthalmic Microcannula is indicated for fluid infusion and aspiration, as well as illumination, during surgery.

The iScience Surgical Ophthalmic Microcannula, or iTRACK, is a flexible microcannula designed to allow atraumatic cannulation of spaces in the eye such as the anterior chamber and posterior segment, for infusion and aspiration of fluids during surgery, including saline and viscoelastics. The microcannula incorporates an optical fiber to allow transmission of light to the microcannula tip for surgical illumination and guidance.
