Can i have a safe lasik therapy. Then?

I am aware of my eye weakness since 2004 (i was born in 1999). In 2004, i was diagnosed with -1.25 power, in both eyes. It steadily worsened upto -8.25 in both eyes, nd is now constant from a couple years. The doctor I used to visit, always told me it is bcz of natural eye growth. My question is, I want to have a lasik laser or some kind of operation (100% safe and pain free), in Delhi, and ensure that my eyes will be all good from then. Pls tell me if its possible easily (blade free, low cost maybe 40k-80k for both eyes, a permanent no side effects no risk solution). Tell me about the success rate, types of operations, when can i have them for me (if I can have at -8.25 power). Pls help me with this, and tell me in as much detail as possible for u. What exactly will be done in the operation, any complications or not, what before what after? For what price of operation, nd where, i can be fully assured that it is going to be very safe and worth it? If lasik can't go beyond -8, then?
