Using the “O&O” Glass Tumbling Barrels:

Particular care, should be taken when loading and unloading the lenses. A little practice might be needed to avoid over-tightening the seal so that the glass thread is not damaged on re-opening.

To close the hexagonal barrel

  • Ensure that there are no glass beads on the convex area of the cap (A).
  • Verify that there are no glass beads on the inner and outer ground area (B and C).
  • Screw the Delrin® cap on to the barrel until the inner glass portion of the cap stops.
  • Twist half to one full turn more, to ensure a leak‐proof seal.
  • Place the barrel on the polishing machine and make sure that there is no leakage. If there is any seepage, tighten the cap by another quarter turn.

To open the barrel

  • Unscrew the cap and wipe off all remaining glass beads on the convex area of the cap (A) and on the inner and outer ground areas (B and C) before inspecting your lenses.

Running-in period for a new barrel:

After manufacture, remaining oxidation or surface modification of the DURAN® glass may, for a short while, cause lens contamination.
Therefore a "running‐in" period is necessary (usually a week to ten days).

For "running‐in" use glass or beads that are expressly for this purpose, adding DI water and Tween 80.

Tumbling Polishing Methods:

Several polishing methods are available on request for Intraocular Lenses.
The most commonly used are the following:
