A Gathering of the top Minds in Corneal Research
Cornea day happened this year on April 25th. The event was organised by the World Cornea Congress, the research arm of the Cornea Society. This year it was held in Boston, Massachusetts, and brought the top minds together in the field of corneal study. The day featured lectures, debates, surgical video reviews, and panel discussions.
As the cornea is often the recipient of different forms of eye surgery, it is a hot topic in eye surgery circles.
What does the Cornea do?
The cornea is the clear part at the front of the eye that helps brings objects near and far into focus. Situated in front of the iris, pupil, and anterior chamber, the cornea helps your lens and anterior chamber to refract light. It changes where the light rays meet on the retina by bending them slightly. It is believed that the cornea accounts for around 66% of our optical power.
Diseases of the Cornea
The cornea can and does attract its fair share of diseases. The most common are shown below:
- Corneal Dystrophy – The cornea loses clarity due to a build up of material in the eye
- Corneal Ulcer – This is due to an inflammatory condition or infection whereby a disruption occurs between layers of the cornea. This causes ulcers to form
- Corneal Neovascularization – This is due to a restriction of oxygen to the cornea. Blood vessels start to grow in the cornea itself
- Fuch’s Dystrophy – Cloudy vision due to disease of the innermost layer of the cornea .
- Keratitis – This is an inflammation of the cornea
- Keratoconus – A degenerative condition whereby the cornea changes shape causing blurred vision
The cornea is also prone to trauma and can suffer abrasions. As you can see a lot can go wrong with this important part of our eye.
Long and Short Sightedness
Myopia (near sightedness) and hyperopia (long sightedness) are often caused by a cornea which is steeper or flatter in curve compared to that of a person with normal clear vision It is also possible to suffer with astigmatism. This is again commonly due to the shape of your corneal surface being more oval than a person with normal vision with a more round spherical cornea.
Eye Surgery and Your Cornea
LASIK and LASEK eye surgery both involve reshaping your cornea to make it more effective at bringing objects into focus. These procedures are used to correct most long and short sighted problems. Sometimes, the condition of the cornea prevents this kind of surgery from being carried out.
Keratoconus treatments have evolved considerably. Prior to Cross – Linking and INTACS treatment, the only way to prevent keratoconus disease was to undergo a corneal transplant. This required a compatible donor, and as such complications arose.
Cornea transplants are still used should the cornea become damaged due to an accident or other treatments are thought to be ineffective.
As you can see the cornea is an extremely important part of our eye, and due to its importance the best minds in the world meet to discuss it. With all new developments in treating eye conditions involving visual errors, where possible, we bring them to our clinic where we use them to help you see better.
