Glasses , LASIK

If your daughter has nearsightedness (myopia), this can be corrected with glasses, contact lenses, or refractive surgery, depending upon her age. If there is any associated astigmatism, this can be treated similarly depending upon the amount of astigmatism present.
I would suggest seeing an eye doctor in order to determine the amount of nearsightedness and/or astigmatism that is present and to discuss the options to correct the problem. Good luck and best wishes.

glasses "fix" nearsightedness - there are surgeries that "fix" nearsightedness - your ophthalmologist can tell you what can and cannot be done at your child's current age.
