Keratoconus is a disease of the cornea, the clear front lens of the eye (like the crystal on a watch), that occurs in the overall population at a rate of about one in 2000. It usually begins in the teens and 20's and can worsen over time. It is often discovered when vision cannot be properly corrected with glasses. Keratoconus results in thinning of the corneal tissues.
Consequently, the cornea bulges out of its smooth, clear, dome-like structure, and assumes a more conical and irregular configuration. Because of this change in shape, the cornea loses its ability to form a clear image in the eye and the patient's vision can decrease drastically. Treatments include specialty keratoconus contact lenses and corneal inlays. However, the keratoconus cornea can continue to bulge over time and some keratoconus patients ultimately may require corneal transplantation to regain vision.
Corneal collagen crosslinking (CXL) using ultraviolet light combined with riboflavin (Vitamin B2) is an investigational procedure designed to strengthen the cornea and decrease the progression of keratoconus. CXL is an investigational procedure and is not approved for use in the United States. However, here at the CLEI Center for Keratoconus, we are participating in a research study of CXL. The goal of the study is to assess the safety and efficacy of crosslinking for the treatment of keratoconus as well as corneal ectasia after LASIK. If successful, CXL may decrease progression of keratoconus and maintain the patient's vision over time.
During the crosslinking procedure, anesthesia drops are administered. The surface epithelial cells of the cornea are then removed and riboflavin drops are administered for 30 minutes. The riboflavin acts both to enhance the crosslinking effect and to protect the rest of the eye from the UV exposure.
The patient then looks at a UV emitting light for 30 minutes. At the conclusion of the procedure, a soft contact lens bandage is applied. The contact lens is left in place to improve healing for approximately 5 days and is then removed. Antibiotic and anti-inflammatory drops are used for two weeks afterwards.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
