Surgical disappointment Presenting the company’s technology during an industry session at this week’s SPIE Photonics Europe event in Strasbourg, Keranova’s scientific director Aurélien Bernard explained that despite the introduction ...

A heart attack, or myocardial infarction (MI), can cause considerable damage to the tissues of the heart, and a better understanding of that damage would be a valuable step towards improved treatment and therapy after the attack. Researchers at the University of Houston have developed a technique based on optical coherence elastography (OCE) that could be used for biomechanical characterization of MI, and be a useful tool to study heart repair. The work was published in Biomedical Optics Express . "About one million people suffer heart attacks every year, and there is currently no cure for the resulting cardiac tissue scarring ...

Optical coherence tomography has become a standard technique in ophthalmology, thanks to its easy fit with clinical workflows and the ability to image particular zones of the eye, such as the anterior chamber and the cornea. Use of the same technique to image the whole eye has proved challenging. OCT's limited imaging depth can be improved though Fourier domain methods and use of modern swept-source laser sources, but the optics of the eye prevent the focusing of light on both the anterior chamber and the retina simultaneously without sacrificing resolution. A project from Poland's Nicolaus Copernicus University and ...

A research effort involving Laser Zentrum Hannover (LZH) in Germany is developing a new, laser-based treatment for presbyopia – the condition that impacts near vision in people from around the age of 40 onwards. At the moment presbyopia – caused by the age-related stiffening of the lens in those affected – is usually treated with simple solutions like reading or bifocal glasses, with multi-focal contact lenses from the likes of Bausch + Lomb becoming available more recently. Some laser procedures have also been developed, but if successful the LZH-led project could lead to a "gentle" new femtosecond laser technique that makes tiny cuts in ...

Carl Zeiss Meditec , the healthcare equipment division of the German optics giant Zeiss, has smashed its annual revenue target after posting sales in excess of €1 billion for the first time. At €1.04 billion, the publicly listed company’s revenues for the year ending September 30 were up 14 per cent on the previous 12 months . And although the weak euro currency accounts for nearly half of that growth rate, the result still saw the company’s stock price rise close to a 15-year high on the Frankfurt exchange.
