LASIK

eye glassesDoes the possibility of LASIK or other vision correction surgery have you ditching your contacts or glasses for good? LASIK surgery is definitely a life changing surgery, but if you are over 40, it might not alter your vision in a beneficial way.

LASIK surgery modifies the shape of the cornea in an effort to flex light in a different manner. The cornea is the clear outermost portion of the eye and is responsible for a majority of visual refraction. Many nearsighted, farsighted, and astigmatism corrections are caused by a mix of the corneal shape and total length of the eyeball.

To remedy standard vision, changing the shape of the cornea with respect to the general eye length will work wonders. This is why LASIK, PRK, and other vision restorative surgeries work and why they focus on the cornea itself.

Many people, however, who once wore glasses for myopia, hyperopia, and some types of astigmatism are now totally free from the hassle of contacts or glasses thanks to LASIK.

Who should not have LASIK? Is there something some corrective eye surgeons are not informing patients?

As we reach 40, vision impairment creeps up. Presbyopia is characterized by a failure to concentrate on objects up close and it strikes everyone at some point in life. Presbyopia is triggered by natural modifications inside the eye to the crystalline lens and surrounding muscle tissue.

People who have presbyopia are led to believe the vision restorative surgery will cure this hassle. The truth is that presbyopia has nothing to with either the cornea or eye length. Improving the cornea in the manner that LASIK surgery does will not assist with an eye’s ability to regain its adaptive focus.

Adjusting the cornea will just create a fixed change in vision while presbyopia requires a dynamic function to be fully fixed.

As of this writing, there are a couple of speculative surgeries being carried out to remedy for presbyopia, however they are not yet mainstream. Some people choose to have one eye corrected for a close quarters reading range, and the other corrected for actual far distance. This method is called monovision.

The best and most trusted method to treat presbyopia is still with a great old fashioned pair of spectacles. Whether progressive, bifocals, or reading glasses; lenses are the only surefire way to fix presbyopia.

If you are over the age of forty and still thinking about LASIK, ask your eye care provider to correct your range vision with contact lenses or glasses initially, and after that take a look at a book or magazine. You will notice that it is more difficult to read and to bring things into focus you will need to hold them even further away.

What this means is that if you are one of those that have been slightly nearsighted their entire life and decide to have LASIK in their forties, you are trading in one pair of glasses for another.

 

Ask your specialist about presbyopia and exactly what you can expect after LASIK surgery. Lots of people still decide to go ahead with the treatment but you want to make sure you are going into the surgery with both eyes open!
