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.
Zap your brown eyes blue.
A California medical company says they have developed the technology to turn your pretty brown eyes into deep baby blues, like Elijah Wood’s.
Circle lenses give you wider-than-life eyes.
Of all the strange outfits and accessories Lady Gaga wore in her “Bad Romance” video, who would have guessed that the look that would catch fire would be the huge anime-style eyes she flashed in the bathtub?
Before and after shots that show the success of the stem cell technique.
Dozens of people whose eyes were severely damaged in chemical accidents have had their sight restored with transplants of their own stem cells.
Sharron Kay Thornton talks with her lead surgeon Victor Perez who restored sight to her left eye.
Doctors in Miami announced Wednesday that they had performed a vision-restoring surgery that used the 60-year-old patient’s tooth.The surgery, the first in the USA, was performed Labor Day weekend at the Bascom Palmer Eye Institute at the University of Miami Miller School of Medicine. Afterward, patient Sharron Thornton was able to see for the first time in nine years. “Sharron was able to see 20/60 this morning. She was seeing only shadows a couple of weeks ago,” says ophthalmologist and surgeon Victor Perez.
Researchers at Stanford University may have just gotten us one step closer to creating a cyborg. They’ve developed a new kind of artificial cornea, one that’s “showing promise” in animal studies and could eliminate the need for cornea transplants completely.
