Contact Lens's and Eye Safety

Approximately 1 out of 20 people will have contact lens related problems.

Are you one of them?

Through recent research it has been found that contact lenses can affect several different areas of the eye. These effects could be simple irritation to more sight threatening complications. You may have experienced some of these problems or just had a concern about them.

The weather, oxygen and their effect on your eyes.

The weather and the wearing of contacts both have an effect. The eye cleans itself from harmful bacteria and other foreign substances through the process of creating what is known as the tear film. Not only does it protect the eye but it also carries the moisture and oxygen to help and protect the eye. The reduced amount of oxygen on the surface of the eye in turn reduces the blood flow to the cornea, which can create complications. While soft contact lenses have less of an effect on this than hard lenses it still does have an effect. And there are other problems that contacts can cause with your eyes.

Now throw in dry weather, the wind and the fluctuating temperatures you can see what your eyes are dealing with on a daily basis. In many instances, the risk to the health of your eyes is greater from wearing contact lenses than from today’s LASIK eye procedure.

And there are the aspects of “chronic wear and tear” from continual contact lens wear to the eye from simply having this foreign substance or particle in the eye. This can predispose an eye to infections and if you might have even experienced these difficulties yourself.

What are your alternatives?

LASIK is the alternative to contact lens wear. While not having them to affect your eyes in a potentially dangerous way is of great benefit you will also receive the benefit of having very improved eyesight if not 20-20.

LASIK and Your Retina

There is a misconception when it comes to LASIK and your retina. Some patients think that because they are having LASIK, the issues with their retina will also be corrected.

This is not true.

Your retina is found at the back of your eye. It is responsible for sending messages to your brain. These messages tell your brain what you are looking at.

You have LASIK to correct a refractive error. Refractive errors occur when the cornea in your eye is misshapen. The cornea, which is found in the front of your eye, should be round and bowl-shaped. If the cornea is not perfectly shaped, then you will experience a refractive error: nearsightedness, farsightedness, or astigmatism.

Light is reflected off of objects and is filtered by the cornea of your eye. When the cornea is perfectly shaped, this light will refract directly onto your retina. If the cornea is misshaped, then the light will not shine directly onto your retina, and this causes double vision, blurry vision, or fuzzy objects.

LASIK works to reshape the cornea into a bowl-shape so that the light will reflect directly onto your retina. It does this through the use of a laser, guided by a surgeon. The laser only affects the cornea and not the retina, therefore it does not correct any issues you may be experiencing with your retina.

A board-certified surgeon should carefully analyze your eyes prior to approving you for LASIK surgery. Most of the risks associated with LASIK occur because the person may not be an excellent candidate for LASIK. Some of these risks include double vision, a fixed or rotating glare, rings of light (“halos”) or starbursts of light. There is also a risk of dry eye, however most patients will experience dry eye for a short time after surgery.
