Abstract: A system that provides for multiple viscoelastic container support and adjustment of a less full container with a fuller container to facilitate, for example, a continuous supply of a protective viscoelastic fluid into the anterior chamber of the eye with minimal operator disruption. The system provides for delivering viscoelastic material to an eye though use of a controlled driver driving a transmission that is in driving communication with an actuator for forcing viscoelastic fluid material from one of a plurality of containers. A viscoelastic material support assembly, which includes a multiple viscoelastic material container retention supporting structure and an adjustment mechanism for adjusting the retention supporting structure relative to the actuator into an injection capable setting, operates to supply a desired amount of viscoelastic material to the eye chamber. The system includes inputs, automated corrections, and visual interaction. Also provided are methods for using the system.

Abstract: The present invention discloses a system and method for delivery viscoelastic, materials into the eye based on the intraocular pressure of the eye, thereby reducing the distraction of the surgeon from other activities involved in the surgery, and increasing the consistency and accuracy of the use of viscoelastic materials during surgery, from surgeon to surgeon.
