Invented eye plaster for retinal cell regeneration


Scientists have developed a synthetic plaster filled with photoreceptor cells, which helps to restore the damaged retina.

The retina degradation due to the death sensitive cells is one of the main causes of vision loss. Previously, researchers have already managed to grow photoreceptor from stem cells in laboratory conditions. Despite the breakthrough, the question of the efficient delivery of spare tissues in the right place remained open.

Now the team of scientists from Wisconsin University in Madison presented a solution in the form of an implantable plaster. It is a very thin frame with cells filled with young photoreceptor cells, on the like tray for ice cubes. At the bottom of each cell there is a circular hole through which the cells grown in the laboratory are connected to the retina.

The implant frame is made of a biocompatible material that has sufficiently high strength indicators and is naturally split in the body in two months. Such a plaster can accommodate up to 300 thousand cells to restore vision.


According to the team, the development is already practically ready for tests on large animals. In the future, scientists plan to improve the implant form and its manufacturing technology.
