An irrigation tube (28) that has a relatively high fluidic resistance. The high resistance can be created by providing a relatively long tube.

The high resistance of the tube will minimize the instantaneous change of flowrate out of the cornea (16) in the event an occlusion is cleared from the aspiration tube (34). Minimizing the change in flowrate will tend to insure a higher flowrate from the irrigation line and a positive pressure within the cornea (16).

Why it's free to use
- Filed April 3, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
