Is there a prescription limit for laser eye surgery?

LASIK can treat most people in the standard range for common refractive errors, but not some people with extreme conditions. There may be other options available if you are outside the recommended limits for LASIK correction. Common refractive errors like myopia, hyperopia, and astigmatism are measured in diopters (D).

What prescription Can laser eye surgery correct?

To be considered legally blind, your visual acuity must be 20/200 or worse in your better eye while you are wearing corrective lenses.

How bad does your vision have to be for Lasik?

Having bad vision that is not bad enough for LASIK is one of these. Normal visual acuity is 20/20. It means you can clearly and accurately see at 20 feet what is reality at 20 feet away. Having 20/100 vision means you should be within 20 feet to see what a person with normal vision can see 100 feet away.

This is a common concern, but rest assured that blinking and moving during LASIK surgery usually is not a problem. Also, a small device will hold your eyelids open during the procedure so you can’t accidentally blink and your eyelids cannot interfere with any step of the surgery.

The Right Age For LASIK

Generally, the perfect candidate for LASIK is someone between the ages of 20 and 40. This is because a major determining factor in LASIK candidacy is a stable eye prescription for at least two years. Just as your body grows and matures through adolescence, so do your eyes.

Candidacy for LASIK surgery is typically not dependent upon age, but upon the stability and health of the eye. While the minimum age for LASIK surgery is 18 years old, there is technically no age limit for laser vision correction. First, your vision must be stable.

That means you see at 20 feet what the average person can see at 200 feet away. So, if you take someone with 20/20 vision and put them 200 feet away from the chart, they would still be able to see the big E clearly. 20/200 visual acuity and worse is considered legally blind in the United States.
