There a number of eye conditions that most of us are aware of. Myopia or short-sightedness, hyperopia or long-sightedness, astigmatism or blurred vision, cataract, and common eye infections that occur every now and them.
But when your ophthalmologist tells you that you have keratoconus, chances are that you will be totally lost.
Keratoconus is a condition where the cornea of your eye starts thinning and bulge in the shape of a cone, causing blurry vision. The term keratoconus translates to cornea shaped like a cone. Keratoconus treatments are now available in Dubai.
Healthy Cornea and Keratoconus
A healthy and normal cornea is more spherical, very similar to one-third of a football. The cornea has a smooth spherical topography, through which the light passes in a straight line, passes through the iris and into the lens, making vision possible.
If you have keratoconus, then the cornea starts thinning and the pressure from inside your eyes will make it bulge outwards. This uneven cornea bends the incoming light and thereby distorting your vision
Causes and symptoms
There is no definite answer as to what causes the condition. Experts suggest that part of the condition is genetic. If a parent has the condition, then the child is monitored closely for the symptoms. There has also been a correlation between keratoconus and people with allergic sensitivity.
The allergies like asthma, conjunctivitis or even dermatitis may put you at higher risk of susceptibility to the condition although these studies are not conclusive. It is believed that constant eye rubbing can cause keratoconus and people with allergic sensitivity usually do it a whole lot more than others. It is unknown whether the condition itself or if it is the action of eye rubbing that leads to keratoconus.
The common symptoms include –
- Blurred and out of focus vision
- Ghosting or overlapped images
- Light sensitivity
- Dry irritable eyes
- Difficulty in reading small prints
The treatment solutions vary depending on the severity of the condition. In the early stages, your vision can be corrected using Rigid lens preamble lenses or RGP lenses. Soft contact lenses may not be sufficient in people suffering from the condition. As the condition progresses, surgical intervention might be necessary.
Intrastromal Corneal Ring Segments or INTACS are insertable contact lenses placed behind the nerves in your eye and requires very less maintenance. These can also be changed according to the changes in the prescription. Patients suffering from keratoconus turn to INTACS when they can no longer use an RGP.
Corneal transplants are performed on people with severe vision loss and scarring due to the progressive peripheral thinning. The surgical options are considered only if other options are no longer viable.
However, keratoconus treatment in Dubai now offers a new treatment method called the cornea cross-linking or CXL, which uses custom-made riboflavin drops to saturate the cornea and then activate it using UV-A light. The eye is then subjected to high sensitivity laser which will restore the patient’s eyes back to its normal functioning.
