The cornea is the clear protective layer covering the eye. Injuries and diseases affecting the cornea might lead to adverse eye problems like blurred visions. The cornea is responsible for filtering out ultraviolet rays that comes from the sun. However, with the advancement in medical technologies and the constant efforts of scientists through research, corneal diseases can be treated. The artificial corneal implants are the most recent of the treatments. Artificial corneal implants proved to be beneficial because: it caters for the huge number of people who are waiting for corneal transplants and operations for instance Europe has a waiting list of over 40000 people and a worldwide list of 10 million. They are also biocompatible ensuring that there are no complications when in contact with the eye surface. In cases where traditional corneal transplants (also referred as corneal grafts) have failed to work, artificial cornea can be used. The risk of getting diseases from donors is also reduced. It prevents astigmatism and enhances rapid visual recovery. Additionally, they are useful to patients who have not qualified to get living cornea donors.
