Is it true that if somebody who has done a lasik surgery may lose his vision if he gets a shock on his head?

I have undergone an intralase surgery last Monday, and I have heard that if someone receives a shock on his head he may lose his vision and this would not be possible to be corrected again?Is it true that if somebody who has done a lasik surgery may lose his vision if he gets a shock on his head?
Lasik surgery always has the chance of loss of vision. Cataract surgery, too. Corneal abraisions. Any procedure to the eye.





And hit on the head can cause blindness.
