I'm thinking about getting LASIK. What are the pros and cons of LASIK surgery?

Pros:
 • It's a quick, relatively painless procedure that can improve vision significantly.
 • There is usually little to no discomfort during or after the procedure.
 • You will be able to see clearly with minimal glasses or contacts needed afterwards.

Cons:
 • It can cause dryness in your eyes, which can take some time to adjust to.
 • Your vision may not be perfect right away due to the healing process.
 • Some people experience headaches, halos around lights, or other side effects from the surgery.
