Intelligent adhesive for the release of drugs in the cornea and treatment of eye diseases



Scientists from Singapore have developed an eye-catching micro-optic adhesive that will improve ophthalmic treatment.

Mille daily reported that Nanyang University of Technology found that glue covered with fine, soluble needles penetrated the eye to release drugs directly into the cornea, which can alleviate many ocular ailments from glaucoma to macular degeneration.

Scientists believe that releasing drugs in this way makes them more effective than eye drops, tablets and painful injections.

Although it may look like a small layer of nails, scientists insist that the glue is painless and easy to use, such as contact lenses, and explains that the elastic glue can be easily pressed by thumb pressure slightly onto the surface of the eye and then removed without it caused a lack of comfort or demanding high skills.

Once the glue is placed, fluid from the eye begins to penetrate into a vacuum between the needles that erodes the fabrics or drugs it carries until the needles reach the cornea. During the next few days, as treatment continues, other drugs will be released.

To prove its effectiveness, scientists have tested glue on rats. When the mice received only one microgram of blood adhering drug per 90% of the affected area of ​​the eye, the scientists found no evidence that the mice suffered from pain and did not detect any bleeding or inflammation in the mouse eyes
