Laser surgery to correct vision problems has been in use since the early 1990s. Photorefractive Keratotomy (PRK) is typically used to correct low to moderate myopia, while laser in-situ keratomileusis (LASIK) is preferred for high myopia corrections. Although over 18 million LASIK procedures have been performed worldwide, there is still some controversy regarding the maximum correction possible and efficacy with this technique.
In the United States, the management of glaucoma costs about $2.5 billion per year. Of the $1.9 billion in direct costs, glaucoma medications account for an estimated 38% to 52% of the total.
Lightscape Technologies Inc., a provider of innovative lighting design solutions, advanced lighting products and customized energy management solutions, today announced that the company has launched its new LED Screen Rental Service and secured its first rental service contract in Hong Kong.
A type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what’s more the vision it does have breaks the rules. Most other insects have trichromatic vision – they are sensitive to ultraviolet, blue and long wavelength light. In a report published in the online open access journal Frontiers in Zoology, scientists reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths.
Himax Technologies, Inc. today introduced a patented technology for LED notebook panels, CMDI (Cascade Modulated Driver Interface). CDMI technology enables thin and light form factor, lower material costs, and lower power consumption for LED notebook panels and supports resolution of up to 1920x1200. CMDI technology has already passed qualifications at certain North America notebook brands and is in mass production.
The ultra-high data speeds possible on optical fibre networks will only come into their own when the fibres reach the last mile into everyone’s home. But that will require miniaturisation and integration of optical components on a scale not yet seen. European researchers may have some of the answers. Broadband access has transformed the economic potential of the internet.
Medicsight PLC, a subsidiary of MGT Capital Investments, Inc., and an industry leader in the development of Computer-Aided Detection (CAD) and image analysis software which assists in the early detection of disease, welcomes the initiative by Barbara Cubin, Republican Representative for Wyoming, to introduce legislation to increase patient access to Computed Tomography Colonography (CTC). CTC is the innovative screening test for colorectal cancer that has the potential to save thousands of lives.
Palomar Medical Technologies, Inc., a leading researcher and developer of light-based systems for cosmetic treatments, today announced an agreement with The Gillette Company (a wholly owned subsidiary of The Procter and Gamble Company) to extend the Launch Decision of a home-use, light-based hair removal device for women until no later than February 29, 2008.
PLC Systems Inc. announced today that it has received the CE Mark Certificate for its RenalGuard System(TM), clearing the way for the Company to begin its initial launch of the product in the European Union.
A Harvard biology professor’s fascination with seafloor microbes has led to the development of a revolutionary, low-cost power system consuming garbage, compost, and other waste that could provide light for the developing world.
When lasers were developed in the 1960s, they were a solution looking for a problem to solve. Since then, they have become an essential tool in industries as diverse as nanotechnology and biomedicine. A new generation of ultra-fast fibre lasers being developed in Europe is creating even more uses for the beams of high-intensity light, while lowering production and maintenance costs and increasing efficiency.
Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic’s Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use “light activation” to kill cancer cells in much more targeted way than similar treatments.
Using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy.
The U.S. Department of Energy has approved a $912-million price tag and an eight-year construction schedule for the new National Synchrotron Light Source II research installation at Brookhaven National Laboratory.
A team of researchers at the University of St. Andrews has developed one of the smallest optical switches ever made.
