Approximately…how Much Would Lasik Eye Surgery Cost For Me?

I am seventeen and have terrible vision with a very rare astigmatism. I live in northern Texas so I’m not positive what the price would be.
The cost of my contacts and glasses are really a hassle because my astigmatism is so rare. My contacts actually run around $300.00 every three months!
So if anyone could inform me AT ALL. I would greatly appreciate it!
Thanks (:
