Important Considerations for People Age Forty
If you are considering LASIK as the procedure to correct your vision and are over age forty, there are several things you should consider when making the decision. As a person enters their forties, they begin to lose the ability for the eye to focus from distance to near called presbyopia. This needs to be taken into account when deciding whether to have LASIK and in what manner is the LASIK going to be performed.
What is Presbyopia?
Presbyopia is the condition when the lens inside the eye that we use to focus loses its ability to change shape and focus objects from distance to near. If you are over forty years of age, then after conventional LASIK you will begin to have problems seeing up close. The loss of the ability to focus up close or read without reading glasses will progressively become worse until the sixties.
What are the Options for having LASIK after Age Forty?
LASIK for both Eyes for Distance
You can choose to correct your vision for distance with LASIK and then you will need reading glasses to see up close. As stated earlier this begins in the forties and gradually becomes worse until age sixty. Every two or three years you will need a slightly stronger reading glass which can be purchased over-the-counter for a minimal amount of money.
Monovision LASIK is the procedure where the dominant eye is corrected for distance and the non-dominant eye is corrected for near if that eye is not able to see up close at the proper reading distance.
Dominant or Non-Dominant Eye
Every person has a dominant eye that is their primary eye. This knowledge can be useful in many circumstances such as in baseball. It would advantageous to have the batter have his dominant eye toward the pitcher.
How do you Test for Dominant or Non-Dominant Eyes?
You cut a quarter size hole in the middle of a piece of paper. You look with both eyes open at an object across the room and hold the paper with both hands and your arms fully extended. You then lift up the paper in front of you and still maintain focus on the object. Now while not moving the paper and looking at the object, you close one eye at a time and see which eye you were using to see the object. That is your dominant eye.
Multifocal LASIK at this time is not approved in the United States but has been performed overseas for several years. The LASIK is performed in such a manner that the corneal shape allows the eye to focus at distance and near. It is under study at this time in the U.S…
