Most people see the eye doctor for a checkup and prescription update every one to three years. It is normal for a person’s optical prescription to change a very small amount every several years. The reason for this is explained in the Refractive Drift section of our “Advanced Optical Issues” page. This slow rate of change “drift” of the prescription through life is not worsened, nor is it eliminated, by having LASIK. After LASIK, if the eyes change, the change will be very slight and should stay close to “zero prescription” point where you want them!
