WHAT IS IT ABOUT AND HOW TO RECOGNIZE IT
TheCORNEAL HYPOXIA occurs mostly in contact lens wear, especially extended-wear lenses, sometimes wearing it also at night. This is a condition in which cornea does not get enough oxygen. In fact, contact lenses form a barrier to the oxygen.
There are two forms: Acute or Chronic corneal hypoxia syndrome.
In the first case, the symptoms are blurred vision, burning eyes and feeling of sand, followed by hyper-lacrimation. Often it found in who forgets to remove the lenses before going to sleep. Usually suspend the use of contact lenses, for a period agreed with your doctor, leads to a full recovery.
The chronic disorder, on the contrary, could be asymptomatic. The continuous damages on the ocular surface, when the wearers don’t substitute the contact lenses or use these over the beyond the recommended time, could lead to a formation of new blood vessels on the cornea (which is normally transparent), flowing into visual disturbances.
It is very important to choose the right type of lens, that fits properly to your eye, with the correct moisture level and oxygen permeability.
Likewise, it is essential always follow the directions of the ophthalmologist to avoid complications. At the first redness or irritation sign, suspend immediately the use of contact lenses and consult the specialist to identify the causes.
Contact lenses should always be handled with clean hands, using appropriate liquids to preserve them and not forgetting to clean well the lens port with disinfectant solution. Adequate maintenance of contact lenses decreases the risk of colonization by pathogenic microorganisms, which can determine the occurrence of CONJUNCTIVITIS or KERATITIS.
