Contact Lenses News and Research

RSS

Contact lenses are explicitly designed optical devices that can be worn directly on the cornea of the eye. People with poor eyesight wear contact lenses, which helps to refocus oncoming light rays on the retina to achieve a clear vision. Contact lenses increase or decrease the focusing potential of the cornea, and thereby directly project light onto the retina and aid in treating refractive errors.

Research could pave way for injectable gels that release drugs over time

Gels are formed by mixing polymers into fluids to create gooey substances useful for everything from holding hair in place to enabling contact lenses to float over the eye.

Scientists produce biodegradable nanocoating with antimicrobial and anti-reflective properties

Scientists from Russia and Switzerland have probed into nanostructures covering the corneas of the eyes of small fruit flies. Investigating them the team learned how to produce the safe biodegradable nanocoating with antimicrobial, anti-reflective, and self-cleaning properties in a cost-effective and eco-friendly way.

Surgeons use patients' own stem cells to rebuild damaged corneas

Surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as "cultivated autologous limbal epithelial cell transplantation" (CALEC).

Duke researchers create first cartilage-mimicking gel that's strong enough for knees

The thin, slippery layer of cartilage between the bones in the knee is magical stuff: strong enough to withstand a person's weight, but soft and supple enough to cushion the joint against impact, over decades of repeat use.

'Smart contact lens' technology can detect and treat diabetes

Diabetes is called an incurable disease because once it develops, it does not disappear regardless of treatment in modern medicine. Having diabetes means a life-long obligation of insulin shots and monitoring of blood glucose levels.

New bacteria-killing light-activated coating

A new antimicrobial coating that can be activated by light has been reported by researchers in the journal Nature Communications, in March 2020. The coating can be used to prevent transmission from computer and phone screens and keyboards, the inside of catheters, and breathing tubes. All these are significant routes of healthcare-associated infections (HCAIs).

Yeasts derived from food can reduce multi-drug resistant fungal infections

A study by researchers in the United States and India has shown that probiotic yeasts derived from food are able to reduce the virulence of, and even prevent infections by, several types of fungi that are responsible for life-threatening infections in hospitalized and immune-compromised individuals, including the multi-drug resistant Candida auris, which was recently listed as an urgent threat by the U.S. Centers for Disease Control in its 2019 Antibiotic Resistance Threats report.
