What is "cornea"?
The cornea is the transparent, dome-shaped layer at the front of the eye that covers the iris and pupil. It plays a crucial role in refracting and focusing light onto the retina, allowing us to see clearly. The cornea is composed of specialized cells and is responsible for most of the eye's focusing power. It is essential for maintaining the integrity of the eye and protecting it from external elements.
Example
Doctors carefully transplanted a cornea into the patient's eye.
I wore an patch to aid in the recovery of a scratched cornea.
Medical advancements have made it possible to transplant not only vital organs but also tissues like corneas.
