Researchers develop 3D printed artificial cornea
Tags: Science and Technology
A team of researchers from Hyderabad have successfully 3D-printed an artificial cornea and transplanted it into a rabbit eye for the first time in the country.
This 3D printed cornea has been made by scientists from LV Prasad Eye Institute (LVPEI), IIT Hyderabad (IITH) and Centre for Cellular and Molecular Biology (CCMB).
This cornea is made from the corneal tissue of the human eye.
This cornea has been completely made by the country's scientists with indigenous technology.
It does not contain any synthetic components and can be applied to patients as well.
How was the 3D cornea made?
Scientists have created a biomimetic hydrogel by extracting decellularized corneal tissue and stem cells from the human eye.
Scientists have said that this 3D printed cornea has been prepared from the corneal tissue of the human eye, so it is completely biocompatible and natural.
This will be helpful in treating diseases like corneal scarring (in which the cornea becomes opaque) and keratoconus (in which the cornea becomes thin).
Many times the cornea of army soldiers gets damaged due to injury, in such a situation the light of those soldiers can be brought back with 3D printed cornea.
What is Cornea?
The cornea is the transparent part of the eye that covers the front of the eye.
It covers the pupil (the centre of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye).
The main function of the cornea is to refract or bend light.
The cornea is responsible for focusing most of the light that enters the eye.
What is 3D Printing?
3D printing uses computer aided design (CAD) to create three-dimensional objects through the layering method.
The model to be printed with the help of software is first developed by the computer, which then instructs the 3D printer.
