laser eye operations

Is it possible to do Laser Operation for any level of eye power?

for example I’ve around minus 3 power for my eyes, can I take to avoid Spectacles??

laser operation is not usually done on people with power greater than -6. So u can surely go 4 it.But laser has its own complications. After the surjury the eye gets very delicate so u hav 2 be very careful like u should not let anythig hit ur eye etc. that means u cant play games like football…there r doctors who do laser surgery but they wear glasses themselves. so i would suggest u 2 get contacts.
