"I'm a student pilot ..... but i'm short sighted..."
Many commercial pilots, nay, most commercial pilots are rather short sighted.............
My daughter had laser eye correction about a year or so ago and found her vision is perfect. She speaks very highly of the procedure. Cost her around $2,500 per eye in Sydney. Not guaranteed, but I think the success rate is in the high nineties - around 97%.
Expect your eyesight to deteriorate with age, rather than the result of laser surgery.
