Keratoconus is an eye problem where the cornea starts to thin and eventually its shape gets distorted. This disease is progressive in nature and can affect both the eyes. Due to this condition, your vision will get distorted, which can’t be corrected with prescription glasses.
This condition mostly surfaces during one’s teenage years or early twenties.
What are the symptoms?
Another problem you may have is sensitivity to light and glare. Also, this condition can cause frequent fluctuations in your eyeglass prescription.
What causes it?
Earlier doctors did not know what caused Keratoconus. They were aware of the risk factors –
Rubbing one’s eyes in a vigorous manner.
A family history of keratoconus.
New research, however, has pointed towards enzyme imbalance in the cornea as the most likely cause. It has been found that an enzyme imbalance makes it susceptible to free radicals damage that can weaken the tissue of the cornea.
Too much exposure to UV rays of the sun is also a risk factor of keratoconus.
There are many ways to treat this condition. The exact method will be determined by your doctor based on how severe your condition. It will also depend upon how quickly the condition is progressing.
Mild versions of this condition can be treated with the help of contact lenses or eyeglasses. But if the disease progresses rapidly along with the shape of the cornea being significantly distorted then these treatment options won’t help.
In such cases, you will have to turn to the following treatments –
In the first method, inserts are placed in the cornea to flatten the bulge and support the structure of the cornea to improve vision.
A corneal transplant involves replacing the affected tissue with the donor tissue. This procedure is only recommended in cases of extreme corneal thinning.
