Trypan Blue
INFORMATION ABOUT TRYPAN BLUE
Trypan Blue Uses
Trypan Blue is used in eye examination.
How Trypan Blue works
Trypan Blue works by gently staining the front layer of the eye’s natural lens, which is usually clear and hard to see during cataract surgery. Coloring this layer blue helps the surgeon see the area more clearly and perform delicate steps like cutting and removing the lens with better accuracy. The dye only colors the surface it touches and does not go deeper into the eye.
Common side effects of Trypan Blue
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
