What is the cornea of the eye?
1 Answer
The cornea of the eye is the outermost fibrous layer. It covers the iris and is transparent and nonvascular.
It can help to focus light because it is curved. It is the most frequently transplanted tissue because it is readily available from cadavers, and the avascularity prevents circulating antibodies from attacking the transplant.
It only contains pain fibers; thus, any contact with the cornea is interpreted as pain. Your eyes are so important that they will close in a nanosecond if damage may happen.
Laser eye surgery is sometimes performed to sculpt the cornea or reshape the surface of the eye and it's done to improve or correct vision and astigmatism. Hopefully there will be no need for corrective lenses.
