For most people, the need to wear eyeglasses to read is an inevitable part of aging. The eyes natural lens hardens and loses its ability to change shape, making it more difficult to focus, especially when reading up close.
With age also comes the development of cataracts or clouding of the eyes natural lens. Intraocular lenses (IOLs) traditionally have been used to replace the eyes natural lens after its removal during cataract surgery. However, with the traditional IOLs, most patients still needed to wear glasses for reading and using the computer. This, however, may be changing.
The FDA recently approved the Crystalens, the first of a new generation of IOLs that, in many cases, can allow people to see without eyeglasses or contact lenses. American Academy of Ophthalmology spokesperson Neil F. Martin, M.D., F.A.C.S., of Chevy Chase, Md., "Unlike older fixed-focus IOLs that do not move, the Crystalens is able to move and can focus like a younger eyes natural lens." The Crystalens use hinges, which are attached to the eyes muscles. This allows the lens to move, or accommodate, so you can focus on objects near, far and all distances in-between seamlessly.

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...
Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
