Refractive surgery often offers improved vision without the hassle of glasses or contact lenses. In general, you have a very good chance of achieving 20/25 vision or better after refractive surgery.

More than 8 out of 10 people who've undergone refractive surgery no longer need to use their glasses or contact lenses for the majority of their activities.

Your results depend on your specific refractive error and other factors. People with a low grade of nearsightedness tend to have the most success with refractive surgery. People with a high degree of nearsightedness or farsightedness along with astigmatism have less predictable results.

Many people have positive results and report high satisfaction after LASIK surgery. However, long-term results often aren't available, as many people are sufficiently satisfied after surgery. They don't feel a need for repeat examination, and they become lost to follow-up. Also, the LASIK procedure has evolved over time, and the procedure done today is different from the procedure done a few years ago.
