Anatomical complexity of the vision system:

To truly understand the challenges of eye transplants, we must explore the intricate workings of the eye itself. The eyeball consists of several crucial components, including the cornea, lens, and retina, all of which play a vital role in vision.

The cornea, often described as the eye’s window, helps to focus incoming light onto the retina. The lens, located behind the iris, further focuses the light, adjusting its position to ensure clear vision.

The retina, rich in specialized cells called photoreceptors, captures light and converts it into electrical signals that can be understood by the brain. The visual cortex in the brain is responsible for interpreting these signals, allowing us to make sense of the visual world.

Each of these components presents unique challenges when it comes to transplants. Restoring vision would require not only replacing or repairing damaged parts but also ensuring their proper integration into the visual system.
