Welcome to HCM.
Looks like your daughter had a Corneal injury
which the transparent part of the eye. Since you have not mentioned how bad is the injury I am not able to comment exactly about the progression in your daughter.
The cornea is made up of five layers all of it being transparent . So any superficial or deep injury to this layer leads to scar formation (like other parts of the body). Which in turn will affect the amount of light getting into the eye causing blurred vision
If the injury is superficial the healing and scarring( mark as mentioned by your doctor) is faster.
If apart from deep layers of cornea, other parts of the eye are involved, then we have to wait and watch how the healing process occurs for a week or two. Until then it's quite difficult to explain the visual outcome of that eye.
So lets hope she has only a superficial wound and its only the cornea that was injured and the rest of the layers are okay. There are procedures like corneal transplants
available if she needs one later (to restore her vision). Don't worry and hope for the best. Take care :).
