In BriefA researcher in the U.K. has developed the world's firstsynthetic, soft tissue retina. Because it doesn't contain any hardmaterials, the device should be able to bypass many of the problemsposed by current mechanical implants. Easy on the Eyes <\/p>\n
Anyone whos ever had a stray eyelash or a piece of dust land in their eye can attest to the pain even the tiniest foreign object can cause. While this sensitivity is essential for keeping our eyes in working order, it can also be a problem for those with retinal implants. <\/p>\n
The retina is a light-sensitive layer of tissue at the back of the eye that plays an important role in sight, and damage to it can lead to blindness. For the past few years, retinal implants have been restoring vision for patients with such problems, but those implants have all been mechanical devices, which can wreak havoc on already damaged eyes. <\/p>\n
The human eye is incredibly sensitive, which is why foreign bodies like metal retinal implants can be so damaging, leading to inflammation and\/or scarring, University of Oxford researcher Vanessa Restrepo-Schild explained in a university news release. To that end, she led a team in creating the worlds first synthetic, soft tissue retina. <\/p>\n
The team used lab-created biological tissue for its artificial retina, and because it doesnt incorporate any rigid foreign materials, the device is less likely to cause problems once implanted. A biological synthetic implant is soft and water-based, so much more friendly to the eye environment, explained Restrepo-Schild. <\/p>\n
So far, the team has only tested its implant in a lab environment, so the next steps are testing it with living tissues and expanding on its functionality. Restrepo-Schild is optimistic about the future practical uses of her creation: I hope my research is the first step in a journey towards building technology that is soft and biodegradable instead of hard and wasteful. <\/p>\n
An estimated 39 million people worldwide are blind, and the Oxford team is just one of many developing bionic eyes to help them regain their vision. <\/p>\n
Right now, the only bionic implant approved by the Food and Drug Administration (FDA) for use in the United States is Second Sights Argus II. That system requires the implantation of a device comprising an antenna, an electronics case, and an electrode array on the patients eye. That implant works in conjunction with a pair of glasses, a video processing unit (VPU), and a cable worn outside the body to restore some of the users vision. <\/p>\n
Other researchers are skipping the eyes altogether in their quest to bring sight to the blind. Monash University professor Arthur Lowerys bionic eyes feed information from a glasses-mounted camera directly into the brain via electrodes. This means it could be used by someone with severely damaged eyes or even no eyes at all. <\/p>\n
Beyond helping people with impaired vision, bionic eyes could eventually give superpowers to those who already have no trouble reading the eye chart. Those implants could allow us to see in different light spectrums, give us telescopic sight, or even record what we see and wirelessly upload it to our social networks. The possibilities are endless, and breakthroughs like that of Restrepo-Schild put us one step closer to that age of superhuman sight. <\/p>\n
