As someone who wears glasses, the idea of corrective laser eye surgery is certainly tempting. But then you start reading about how the invasive surgery is actually performed, along with some of (admittedly rare) risks, and suddenly glasses don’t seem so bad. Things could change, however, thanks to research coming out of Columbia University. Researchers there have developed a new noninvasive laser eye surgery which could permanently correct vision — minus any of the less pleasant-sounding aspects of regular laser surgery.
Researchers at Newcastle University have been able to 3D-print a biocompatible corneal framework using a new gel formulations that “keeps the stem cells alive whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer.”
There is a significant shortage of corneas available to transplant, with 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder,” wrote the researchers. “In addition, almost 5 million people suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease.”
Dua’s layer, a new layer of the human cornea.
A new discovery to the human anatomy is just 15 microns thick, but it will make eye surgery safer and simpler. Harminder Dua, a professor at the University of Nottingham, recently found a new layer in the human cornea, and he’s calling it Dua’s layer.
