Contact Lens That Can Release Drug Could Be Used To Treat Glaucoma

Slashdot - 9 hours 40 min ago
An anonymous reader quotes a report from The Guardian: Researchers in China revealed they have developed a contact lens that can sense an increase in pressure within the eye and release an anti-glaucoma drug should the pressure exceed a certain level. Writing in the journal Nature Communications, the team describe how they created the device using an upper and lower lens, with a snowflake-shaped pressure sensor and wireless power transfer device sandwiched between them around the rim of the lenses. The arrangement appears to give the effect of the wearer having golden irises. However, the team say the design allows the necessary components to be included in the device without blocking the wearer's view or irritating the eye. When the pressure inside the eye increases, the gap between the upper and lower lenses decreases. This is detected by the pressure sensor by means of a cantilever. The sensor then sends a signal to the wireless system which subsequently triggers the release of an anti-glaucoma drug, from a hydrogel attached to an electrode, and enables it to cross the cornea of the eye. The drug, brimonidine, acts to reduce the pressure within the eye. The study reveals that the contact lenses have so far been tested on pigs' eyes and on the eyes of living rabbits -- albeit with smaller-sized lenses -- although trials have yet to be carried out in humans. The researchers note the lenses are not only soft and minimally invasive but are also battery-free, adding that the approach could be expanded to help tackle other eye diseases. "We can now imagine that a glaucoma sufferer wearing these contact lenses will not only receive real-time information about the pressures within the eye, since the contact lens has built-in wireless capacity and can easily communicate with an app on your smartphone, but also receive, for example, pressure-relieving drugs when needed," said Prof Zubair Ahmed from the Institute of Inflammation and Aging at the University of Birmingham. "The materials required to create such contact lenses are inexpensive and soon could be mass-produced," he added.

South Korea Turns To Surveillance As 'Ghost Surgeries' Shake Faith In Hospitals

Slashdot - 12 hours 40 min ago
After scandals in which doctors let unsupervised assistants operate on patients, South Korea is becoming one of the first to require cameras in operating rooms. The New York Times reports: Ethicists and medical officials, including those at the American College of Surgeons, have cautioned that surveilling surgeons to deter malpractice may undermine trust in doctors, hurt morale, violate patient privacy and discourage physicians from taking risks to save lives. The Korea Medical Association, which is opposed to the new mandate, has lobbied to limit its impact. But supporters of the law said the move would help protect patients, build the public's trust in doctors and provide victims of medical malpractice with evidence to use in court. "People are dying in operating rooms," said An Gi-jong, an advocate for patients. "We can't rely on doctors to solve problems on their own anymore." About five patients have died from ghost surgeries in the past eight years, he said. They include Kwon Dae-hee, a college student in Seoul who died of a hemorrhage in 2016 after jawline surgery. His mother, Lee Na-geum, who obtained footage of his operation and reviewed it hundreds of times, found evidence that the operation had been botched because parts of it had been conducted by an unsupervised nursing assistant. Ms. Lee, 62, who has held a public vigil denouncing ghost surgeries since her son's death, said in an interview: "Once the cameras are installed, your lies will be exposed if you're a ghost doctor. Cameras reveal truth." [...] Under the new law, hospitals performing surgeries on unconscious patients must install video cameras in their operating rooms. If a patient or a relative requests that a surgery be filmed, the hospital must comply. Doctors can refuse for certain reasons, such as if a delay in the operation would put the patient's life at risk, or if the filming would significantly impede residents' training. The recorded footage can be viewed for criminal investigations, prosecutions, trials, medical disputes or mediation.
