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.

Abstract: A phacoemulsification device has a cutting tip for insertion into an eye and contact with a cataract. The device includes a shaft having a phacoemulsification movement generator connector end, an applicator tip supporting end, and a shaft section extending between the respective ends of the shaft. The shaft section has a convoluted exposed surface comprising longitudinally extending projections and longitudinally extending valleys arranged in sequence about the circumference of the shaft section. The projections are free of any edges as in, for example, an embodiment that includes projections and valleys that have smooth sloped curving walls in cross section and include a plurality of mirror image S-shaped regions extending from a maximum radial extension of a first projection, down to a maximum depth of a first valley and up to a maximum radial extension of a second projection, with the valley positioned between the first and second projections.

Abstract: A phacoemulsification device that features an applicator tip as in a cutting tip for insertion into an eye and into contact with a cataract. The device includes a shaft having a phacoemulsification movement generator connector end at a proximal location and an applicator tip supporting end at a distal end, and the shaft further includes a shaft section that extends in a region positioned between the proximal and distal ends of the shaft, and the shaft section having a convoluted exposed surface which includes longitudinally extending projections and longitudinally extending valleys arranged in sequence about the circumference of the shaft section.
