New Breakthrough For Cornea Transplantations, No More Waiting List!

Story Highlights
  • The success of the surgery
  • Why is it better?

After undergoing surgery, those who are legally blind or visually impaired may be able to regain their sight using corneas that were produced from pig collagen, according to the findings of certain researchers.

Since a human donor is required to undertake a corneal transplant, the chances of acquiring one are one in seventy. But a researcher at Linkoping University in Sweden named Mehrdad Rafat overcame this seemingly insurmountable obstacle by developing a contact lens made of extracted and purified pig collagen that is both flexible and durable.

The success of the surgery

The condition known as keratoconus, which causes the cornea to become thinner and protrude outward from the center of the eye, was the root cause of corneal blindness in all twenty people who took part in the study.

Before undergoing surgery, 14 participants in the research were regarded to have a level of vision that was believed to be clinically blind, while another 6 participants had considerably impaired vision. All of the patients who participated in the study had their eyesight improved, and three of them reported having 20/20 vision after their surgeries.

After two years had passed after the procedure, and study participants who had been recipients said that they had not experienced any significant bad effects or problems.

Why is it better?

As collagen does not contain any particular cells, the immune system does not often react negatively to its presence. Therefore, to prevent the organ from being rejected by the body, the patients are only required to use immunosuppressive eye drops for the first eight weeks following surgery rather than taking a drug intended to be used permanently.

Rafat is more optimistic about his discovery and claims that the procedure may be less expensive than a transplant surgery that requires a human donor.
