Needless to say, diabetes is a long-term chronic disease with endless complications. Remember, poor management can lead to a higher risk of developing diabetic retinopathy, which is caused by damage in the retina induced by high blood sugar levels. If retinopathy is not treated in time, it can gradually lead to low vision and even worse, blindness.
However, Professor Sei Kwang Han and Ph.D. candidate Jeon-Hui Lee (Department of Materials Science and Engineering), together with Dr. Sangbai Xin of PHI Biomed Co., has developed a smart wearable LED contact lens, which can help prevent and treat the condition at an early stage. Is.
LED contact lenses prevent retinopathy by irradiating 120 watts of far-red/LED light directly into the retina. To test the innovative device, the researchers tested it on animal models of diabetes for a total of 8 weeks.
And, it was found that, at 8 weeks’ time, animals who wore lenses for about 15 minutes 3 times a week did not develop the condition, on the other hand, animals that did not wear lenses showed signs of retinopathic conditions. .
The condition is not difficult to diagnose. An ophthalmologist (eye doctor) can easily diagnose diabetic retinopathy by running a simple test, in which the doctor will monitor for abnormal or growth of blood vessels, bleeding in the center of the eye, and swelling of the retina.
According to the Cleveland Clinic, when the condition becomes severe, a person may have symptoms such as trouble reading or seeing distant objects, blurred or distorted vision, color blindness, poor night vision and small dark spots.
Conventional treatments for diabetic retinopathy include two highly painful procedures—one is highly invasive, in which repeated therapeutic injections are given to the eyeball, meanwhile, in other procedures, the patient undergoes thousands of small burns after being given anesthesia. which are done with a laser. To destroy the capillaries near the retina.
