Scientists Create Artificial Retina Implant That Could Restore Vision
Scientists have recently designed and developed an artificial retina and with the use of this artificial retina, the lost vision of rats can be restored. Scientists are expecting that in one year time they will be able to develop such artificial retina which will be helpful in order to restore vision in human eyes.
The retina implant which is designed has the capability of converting any light into an electrical energy which can easily stimulate the retinal neurons. Therefore, if this implant is properly designed then it can easily light the eyes of the people who have faced a breakdown in the photoreceptor cells.
The retina which is consists of millions of photoreceptor cells is placed right behind the eye. The breakdown of photoreceptor cells can occur due to the mutation of 240 identified genes. Previously scientists used to treat the retina of the eyes. But now the concept have changed and now they are looking to cure the blindness problem with the help of CRISPR genes.
A team which is formed by Italian Institute of Technology is looking for a new approach. The team is thinking that an implanted Prosthesis can do the job. Scientists believe that this implanted Prosthesis can be an ideal replacement for a damaged retina.
The developers have confirmed that they are looking to build the prosthesis implant with the help of a silk-based substrate. At the same time, the implants will be covered by a semiconducting polymer.
According to the Royal College of Surgeons, the semiconducting polymers can work as a photovoltaic material. At the same time, it will be very efficient in order to absorb photons. The researcher has tested this concept in a rat's eye and so far it is looking really good.
It is expected that the trials on humans may start in the mid of 2018. If the trials on humans is a success then it can be a revolutionary discovery in the medical science.
