When we have a syringe that is filled with liquid, be it balanced salt solution or visco-elastic, we have a high pressure situation that could result in an iatrogenic trauma and complication. The syringe is capable of causing high pressure that can cause a traditional Luer-lock cannula to shoot off into the eye and damage the delicate ocular structures.
The key to using these syringes is to hold them with a firm grip at the cannula tip, much like holding a pencil tip. This prevents the cannula from shooting off the tip of the syringe if it is occluded.
