Abstract
Twin bore ophthalmologic tubing includes first and second tubes. The second tube has portions of differing hardness with one of the portions being at an end of that tube. The second tube has a portion at its other end with about the same hardness. Portions of the first and the second tubes may have about the same hardness. In some embodiments, portions of the first and second tubes with the same hardness can correspond to each other along the tubing. One of the portions can have a hardness of 80 to 90 shore A while the other portion can be 60 to 70 shore A. In some embodiments, portions with 60 to 70 shore A hardness can be about six to twelve inches long.
