The human eye is a bit more complicated than we first thought. Scientists have discovered a previously undetected layer in the cornea, the clear window at the front of the eye. The findings could dramatically improve surgeries that involve corneal grafts and transplants.
Named the Dua Layer after the professor who discovered it, this new layer is located at the back of the cornea between the corneal stroma and Descemet’s membrane. Although it’s just 15 microns thick, it’s incredibly tough and strong enough to withstand one and a half to two bars of pressure.
