Which of the following eye part is 3D printed by Scientists in 2018?

Cornea

The correct answer is Option (4) - Cornea

Cornea:

• The cornea is the clear front portion of the eye, encompassing the iris, pupil, and anterior chamber.
• Responsible for refracting light along with the anterior chamber and lens, the cornea plays a crucial role in vision.
• Addressing the scarcity of eye donors, scientists have developed 3D printed human corneas, offering a potential solution.
• This advancement aims to provide vision to millions suffering from blindness and prevent corneal blindness due to conditions like trachoma.
• The dimensions of the printed cornea closely match those of an actual human cornea to ensure shape and size accuracy.
