Mediterranean diet may have protective role in AMD, study finds

NICE, France — The Mediterranean diet, combined with physical exercise, might have a protective role in the development and progression of age-related macular degeneration, according to a Portuguese study. The study, which was the first to specifically evaluate the role of the Mediterranean diet and lifestyle habits in AMD, was developed within the larger epidemiological AMD Coimbra Eye Study, a cross-sectional population-based study including subjects aged 55 years or older from two Portuguese populations, one from a coastal town and one from an inland town.

Contact lens case changes color to signal bacterial contamination

SAN DIEGO — Researchers have developed a microbial sensing device that alerts contact lens wearers of unsafe levels of bacteria and to discard the lens. They presented their findings at ICAAC 2015.“We have devised a real-time sensing device, embedded within a contact lens case, that is capable of signaling the presence of abnormal levels of live microorganisms,” Nishal Govindji-Bhatt, PhD, a postdoctoral research associate at the University of Manchester, said in a press release.

AAO and ASCRS set guidelines on postop co-management, transfer of care

The American Academy of Ophthalmology and the American Society of Cataract and Refractive Surgery have issued a joint position paper with guidelines on co-management and transfer of care after ophthalmic surgery.“Co-management is a relationship between an operating ophthalmologist and a non-operating practitioner for shared responsibility in the postoperative care when the patient consents to multiple providers, the services being performed are within the providers’ respective scope of practice and there is agreement between the providers to share patient care,” the paper said. “Transfer of care occurs when there is complete (Read more...)

Publication Exclusive: Fallout from failed clinical trials poses challenges to companies

So far in 2015, four different ophthalmic products in phase 3 clinical trials failed to meet their primary endpoints. Ocular Surgery News spoke with three of these companies to find out what happened and how they responded. Their stories offer a telling glimpse at the challenges and opportunities companies face when endpoints are missed in clinical trials as part of the overall innovation cycle.“Private companies often simply learn from their experience and make appropriate adjustments to their research and business plan. They continue on as long as their investors are (Read more...)

Endophthalmitis rate after intravitreal injections comparable to rate after cataract surgery

BARCELONA — Data from the Swedish Macula Register showed steady growth of intravitreal injection volume over the last 7 years and a stable low incidence of endophthalmitis with a slight increase in 2014. “Between 2007 and 2014, we had 18,802 patients, 21,811 eyes, 304,401 visits and 145,747 treatments. Numbers have been growing steadily. Treatments were just over 2,000 in 2007 and nearly 36,000 in 2014,” Inger Westborg, MD, said at the European Society of Cataract and Refractive Surgeons meeting here.

Zeiss builds on range of ophthalmic products

BARCELONA — Carl Zeiss Meditec introduced additions and enhancements to a range of ophthalmic products at the European Society of Cataract and Refractive Surgeons meeting.In particular, Visuconnect 500 software adds networking capability to Zeiss’s line of basic diagnostics devices, Opmi Lumera 300 is a new surgical microscope, and the SL 220 slit lamp features a new user interface and tower design, Ralf Kuschnereit, PhD, head of the Ophthalmic Systems Division, reported at a company press briefing.

Complicated cases bring out the best in femtosecond laser cataract surgery

BARCELONA — While most surgeons are still using femtosecond laser-assisted cataract surgery only in standard cases, in which no significant difference from classic phaco has yet been demonstrated, the true advantages are in a wide range of complicated cases, according to José L. Güell, MD.At a symposium on femtosecond laser cataract during the European Society of Cataract and Refractive Surgeons meeting, he showed examples of several situations in which laser makes the difference for the surgeon and the eye he or she is operating on.

Pupil expansion device gently deals with small pupil problems during cataract surgery

BARCELONA — A new pupil expansion device allows a safer, gentler approach to intraoperative floppy iris syndrome, pseudoexfoliation and small pupils during surgery.The I-Ring pupil expander (Beaver Visitec) is made of soft polyurethane, as opposed to the stiffer polypropylene more commonly used in pupil expansion devices. It is preloaded in an inserter and injected through the phaco incision.
