Artificial Cornea To Reach Patients This Year

kkleiner writes "A German-led team of researchers has developed a new version of an ophthalmological polymer to which the eye will bond and still function normally. 'The new polymer could help restore sight to thousands waiting for corneal transplants around the world. The artificial cornea has passed clinical trials and is ready to see expanded use in patients this year. ... In order to work in the human body, an artificial cornea has to meet some stringent requirements. First, it has to bond to the human eye around its edge. ... The center of the artificial cornea, however, does not promote cell growth and remains clear so that it can be seen through. The artificial cornea also has to move freely with the eyelid and balance moisture on its faces.'"

Having a new cornea put in?

So you'd have your cornea removed and a new one put in? As someone who's had many eye injuries in my life, let me be the first to say "ouch".

People who use laser eye surgery to correct their vision can only do so a limited number of times. After that, a cornea would need to be replaced. Ideally, a replacement cornea would be able to correct vision without further adjustments.

More importantly, there are a number of diseases related to the cornea that ultimately necessitate a corneal transplant. Technology like this would obviate the need for tissue donation, which is a huge step for people suffering from such illnesses.
