3.2.1 Viscoelastic with cannula
To model this tool, we observed and studied a real tool as the one
shown in figure 5. This tool is used for placing the viscoelastic
material into the anterior chamber of the eye during the
capsulorhexis stage of the cataract surgery procedure. It basically
consists of a syringe with the viscoelastic material inside and a
slightly bent tip.
