Laser eye surgery to remove errors of refraction (LASIK) was first developed and used for near-sighted individuals (myopics) such as yourself.

For as long as you will qualify as a candidate for LASIK, and pass the qualifying tests (i.e. stable refractive error for at least a year, at least 18 years of age, with no or controlled dry-eye syndrome and enough corneal tissue to work with). You can go for the procedure.

It would be best to see an ophthalmologist so you can discuss further. One of the most important things that a LASIK candidate must have is a realistic expectation of the results of the procedure.
