Sight is one of the most important human senses. When it is lost, it is almost impossible to recover because of the many processes that the body has to perform to optimally execute this function. However, there is a new method that has been successful Bring light back into the eyes of 20 people who are totally or partially blind.
Advances in science generally focus on improving the quality of life for humans. Cure diseases and optimize the function of every process in the body, in an economically accessible way, is the north that many people follow.
Although we know that a sector of society has impossible treatments, it points to things that are within the reach of the pocket of any social class, who want to restore the sight of blind people.
As per the portal publishing The Cuban DebateScientists are responsible for creating this method to restore vision Linköping UniversityIn Sweden, with experts from the company Lincocare.
The researchers developed a prototype artificial cornea with which 20 diseased volunteers were induced to regain their vision after receiving the implant. When the results of this experimental study were published, they received support from the scientific community revista Nature Biotechnology.

How was the artificial cornea made to restore sight to the blind?
When the cornea is damaged, it is very difficult to repair it. It is possible only through organ donation from another human being. About 13 million people are blind due to the same problem, and only one in 70 sufferers benefit from a donation.
To the work of these specialists who made this artificial cornea using an implant made of collagen proteins from pig skin. This substance, especially in the animal kingdom, is very similar to the human cornea.
“The results show that it is possible to develop a biomaterial that meets all the criteria for use as human implants, which can be mass-produced, stored for up to two years, and reach more people with vision problems. “We have made significant efforts to ensure that our development is affordable and widely accessible to all, not just the rich,” said one of the project’s lead developers.
This treatment is called targeted eye disease Keratoconus. This is an injury where the cornea becomes very thin and can cause partial or total blindness.
Clinical trials were conducted in India and Iran. 14 of the 20 volunteers were completely blind. The first tests started two years ago and today all have recovered their vision, with three cases recording 20/20 (perfect) vision.
