 In the event that you're not sure whether your wound is watertight, we are fortunate to have a product called Reshore Sealant. It's a hydrogel sealant, very comfortable to the eye, made out of the same material that contact lenses are manufactured from. Put two drops of the diluent in the blue over the blue dot and mix it using the back end of the special spears that are provided by ocular therapeutics. You mix it for five seconds and then you have 11 to 12 seconds to apply it before it polymerizes. So the blue will disappear in about an hour. That's just there to give the surgeon good visibility.
