Researchers in Spain have developed a low-cost artificial eye from fish scales

Researchers from Spain's University of Granada developed a.. artificial cornea made..from the scales..of several fish species that are commonly found on markets. This..could be a..lower-cost option to..donor transplants..for severe eye disease.

It is hard to repair the cornea, which is the transparent layer of the eye. This is because it lacks blood vessels and has a limited capacity for regeneration. The treatment of severe corneal disease often involves?donor?transplants. However, organ availability and waiting lists can limit the number of transplants available.

In a press statement, scientists from the University's Tissue Engineering Group (TEG) and the ibs.GRANADA Biomedical Research?Institute claimed that they had developed corneal implants made of fish scales which were "highly biocompatible and transparent".

Ingrid Garzon is a professor of histology and co-author of the study. She said that due to its origins, the product was very "accessible", easy to obtain, and cheap. It could also help boost local fishing.

Although testing has shown that the technology could be used to repair and regenerate corneal tissue, it is still far from being clinically useful in humans.

The team stated that the material showed good results in both laboratory tests and in animals who received implants.

The'release' stated that "although the standard transplant is usually successful, it is necessary to develop new effective regeneration methods which do not depend on organ donations, which are subject to long waiting lists." Miguel Alaminos also works as a professor of histology at the same university.

Researchers at Antwerp University published a peer-reviewed article in 2016 that found artificial corneas made from fish scales to be biocompatible for humans.
