Keratoconus Disease Information
The Keratoconus Disease
is a progressive Eyesight Disorder
that forces the round and smooth Cornea
into a cone shape. The cornea converts light into clear and sharp images.
Whenever the shape is toyed with, the light is unable to properly pass through the eye. This confuses the eye and instead of seeing one direct image, it sees several different images coming through.
When the eye is unsure which is the true source, it projects Double Vision also known as Diplopia or triple images. Being able to properly see distances can also be a Eyesight Problem.
The Keratoconus disease is sometimes extremely hard to spot because it starts to foam slowly. This makes it hard to prevent because when it is encountered it is already too late to take necessary steps to reduce it.
When the cornea starts to become affected, the person will have Myopia also known as Nearsightedness or short sightedness and will start to have Irregular Astigmatism.
Constant changes to Prescription Glasses should also be cause for an alarm. The eye typically should remain at the same power and only small adjustments to the prescription should occur over the course of several years – not every visit. Distortion and Blurry Vision are one of the symptoms along with sensitivity to light.
People are still unsure as to why Keratoconus disease occurs. New research has come up stating that the reason why Keratoconus could occur is due to a lack of or imbalance of an enzyme within the cornea.
This could be genetic or caused by environmental factors. There have been several cases showing that more than one member of the family will develop Keratoconus. People who have been exposed to too much ultraviolet rays from the sun could also be more likely to get Keratoconus.
Extreme eye rubbing or poorly fitted Contact Lenses can also be the cause. However, the evidence is still too early to know for sure.
There is no real way to Protect Your Eyesight once you start to have it. Contact lenses and glasses can greatly help the disease while it is still in its mildest foam.
Once the cornea becomes more cone shaped though, these methods will no longer help correct Blurry Vision. You will have to start wearing special contact lenses called Gas Permeable Contact Lenses.
These lenses are able to present a smooth surface, which will greatly help light enter in an even fashion. However, due to the shape of the cornea, it is really hard to fit these contact lenses. You will probably have to go back to the eye doctor's office more than once in order to get a near-prefect contact lens fit.
When this occurs, the eye care practitioner might recommend wearing two contact lenses in order to reduce discomfort. One Soft Contact lens and then the Gas permeable lens. This is called 'piggybacking'.
Typically the Eye Care Professional or
Eye Care Specialist will over see the process and make sure that there is enough oxygen entering into the eye.
Lack of oxygen can cause blood vessels to burst in the eye, watery eyes, and can become incredibility uncomfortable.
