If you wear contact lenses or glasses for your visual impairments, an annual eye exam with an eye doctor is usually necessary to update your glasses. Patients will typically need to commit time and money to this type of maintenance. If you are considering LASIK, you should know that your outstanding laser vision correction results will usually last for many years. As your eyes age over time, there may be a change in your vision over the course of several years. Occasionally, if these changes make you feel blurry, you may benefit from an enhancement procedure to address any of this blurred vision.
