Artificial Eye Lens with Liquid Crystal Replaces Reading Glasses

Generation from 50’s should remember this name: Devesh Mistry. Because the British scientist paves her just the way for a future without reading glasses: Mistry has an artificial eye lens liquid crystals developed that will be used with far sigh tedness and cataracts.

The flexibility of the eye lens decreases with increasing age. From about 45 years, it can come to the hyperopia. Small print is hard to read and even use a Smartphone can be a challenge to. Since you need reading glasses.

Prototype of an electrically switchable lenses

Devesh Mistry – British Leeds University researchers has now developed an artificial eye lens in the framework of his PhD thesis, which could replace the traditional reading glasses.

But also people who suffer from cataracts, an eye disease, in which the natural lens is clouded, could benefit from the new lens. Liquid crystals are his solution for interacting eye lens as used in smartphones, tablets, and TV monitors. In 6 to 10 years first patients could benefit from it. And finally discarded the reading glasses.

Not solid and not liquid – Artificial Eye Lens with Liquid Crystal Replaces Reading Glasses

The properties of liquid crystals are ideal for the lens of the eye: so the material has direction-dependent properties, which are necessary for the movements of the eye lens. And can respond to stimulation of the eye. “Liquid crystals are a very under-rated phase of matter,” said Mistry told the times. “Liquid crystals lie between Crystalline Solids and Liquids. They have an ordered structure such as a Crystal, but she can flow like a liquid and respond to stimulation.”

Muscles in the natural lens close up, depending on what the viewer just look at – and be as sharp. But over the years, the lens in the eye is stiff. The focus on things in the vicinity no longer works. The so-called farsightedness occurs.

In the case could in the future, the eye surgeon be used and place the new liquid crystal lens. For this, an incision in the cornea must be carried out. While the old lens with the help of ultrasound is broken. A local anesthetic should suffice for the operation.

Interacts with the eye muscles

After successful surgery, the liquid crystal lens now takes over the task of the eye lens become slack. The artificial lens absorbs the muscle movement of the eye and adapts itself to you.

Devesh wants to finish a workable prototype by late 2018. In about 6 to 10 years the liquid crystal lens to come after his performances into a trade. For this he works with the specialist for contact lenses, ultra vision CLPL and Eurolens research at the Manchester University.

A Canadian optometrist has already developed a Bionic Lens, which aims to improve the vision at all distances and enormously. She is the clinical tests, the Bionic Lens could be already 2017 on the market.
