To treat nearsightedness, the steep PMF Advanced Proof Review cornea is made flatter by removing tissue from the center of the cornea. This moves the point of focus from in front of the retina to directly on the retina.To treat farsightedness, the flat cornea is made steeper by removing tissue outside the central optical zone of the cornea. This moves the point of focus from behind the retina to directly on the retina.To treat astigmatism, the cornea is made more spherical - like a basketball instead of a football. This eliminates multiple focusing points within the eye and creates one point of focus on the retina. Astigmatism can be treated at the same time as nearsightedness and farsightedness.
The effects of LASIK are permanent. The effects of LASIK do not wear off. But, it is important to realize that a person's eye can still change internally. That is why many surgeons recommend having the procedure done after the major eye changes have occurred in one's life. For instance, LASIK is not recommended on children because their eyes change a great deal. They would need the vision fine-tuned in a few years. If the procedure is performed after the age of 18, the chance of long-term stable correction is more likely. Even the eyes of patients over the age of 18 can still be changing. Therefore, we recommend a good conversation with your surgeon so they can review the changes you have had and help you make a decision whether or not you should wait until the changes have slowed down. Patients should also note that while results are usually stable, they can be modified by enhancement procedures - procedures performed after the initial one - if necessary.
You can resume most normal activities immediately after surgery. You should wear safety glasses while playing contact sports whether or not you have had surgery. But, if you do not routinely wear safety glasses, your surgeon may recommend wearing them for at least one month after LASIK. You will also need to avoid such activities as contact sports and swimming for several weeks. It is important to talk specifically with your doctor about limitations on activities after LASIK.
