Everyone‘s talking about me, I feel notorious.
The medical eyesight chart that was posted is pretty much accurate. Your vision correction, nearsightedness, farsightedness, colour vision, and any problems like astigmatism are all taken into account, and any problems may bar you from certain trades, or from the CF in general.
As for Laser Eye Surgery, you‘d be hard pressed finding a place that charges you $5000 for the surgery. LASIK is by far the best route, unless you have really terrible vision or your corneas are too thin. When looking for a surgeon, get their full name and make a quick phone call to the College of Physicians and Surgeons. Ask them if the doctor is in good standing, has had any malpractice suits, etc.. Also, call the Better Business Bureau to find out if they‘ve had any problems.
Laser surgery, unlike most other surgical treatments, are done by the thousands. One laser surgeon could easily do 1,000 corrections in the space of a single year, so keep that in mind when you‘re shopping around. As for price, make sure it‘s "all inclusive". The price they set should include an optemetrical exam beforehand and afterwards, all treatment, subsequent checkups, and the meds and tape that they send home with you after the surgery (eye drops, antibiotics etc.). Often, the price that you think is a huge savings is a lot more than you think once you add up all the extra costs.
There is a chance that your eyes can regress afterwards, or require a second treatment, or get an infection, or even go blind. These are all pretty rare, and the vast majority of people come out with 20/20 vision. However, with any surgery there are risks, and it‘s something that you have to consider before going into anything, and certainly before signing that little waiver form.
