We only perform laser eye surgery on ages 18 and older. Two reasons for that:
1- one needs to be of legal age inorder to sign a medical consent form.
2- More likely than not that the prescription will continue to change till into the 20’s. Best to wait for the prescription to stabilize in the mid twenties before we laser the eyes.

If she is a responsible girl, you may consider fitting contact lens with supervision for proper use.
In most cases, this applies to patients with myopia (near-sightedness). If she has hyperopia (far-sightedness), this can continue to increase for a longer time and so she might not be a candidate even after she is fully grown because the refraction is not stable.
Exceptions are made in children for when one eye is much weaker than the other and is at risk for losing vision (amblyopia). This is typically done at an academic center after careful consultation and review by pediatric ophthalmologists if all other options have been exhausted.
