Thousands and thousands of eye surgeries go wrong each year – mainly because there is so much we still have to learn about ourselves. A good example of this is the Dua’s layer, a newly discovered layer of the cornea scientists and doctors didn’t even know existed. It turns out that the cornea, the clear part of the eye that covers the iris, doesn’t have five layers – it has six, which with this new knowledge, will make many more eye surgeries in the future much more successful.
Dua’s layer, discovered by Harminder Dua, a professor at the University of Nottingham, is only 15 microns thick, and was found by separating the corneas of many donated eyes with pressurized air. It is suspected that Dua’s layer is the cause of the previously mysterious corneal hydrops, a disorder whose symptoms include eye irritation and the build up of fluid in the eye. This disorder has led to many botched eye surgeries, infections, and loss of sight.
