What happens if the eye gets stabbed?

Depends: The amount of eye injury depends on the amount and tye of ocular tissue disrupted by the perforation. If the object penetrates, but doesn't perforate the eye, trauma may be minimal. Perforating injuries of the lens cause cataract, the iris can tear and bleed . Retinal trauma can be devestating. A rupture to the cornea or sclera cannot always be repaired. Velocity of the injury can also disrupt.

Bad things: This is a very bad place to get stabbed.
