According to the Russian "News Island" news network on February 16th, American scientists found that the insertion of nano-diamonds into contact lenses to deliver drugs is more conducive to the treatment of glaucoma.
According to relevant experts, by 2020, about 80 million people worldwide will suffer from a terrible eye disease, glaucoma. If the patient is not treated in time, it can damage the optic nerve and eventually lead to blindness.
In patients with glaucoma, the decomposition of the ocular tissue is caused by fluid deposition, which creates a burden on the eyeball. Usually doctors recommend eye drops to prevent glaucoma to reduce fluid production. Unfortunately, many patients do not follow the doctor's prescribed dosage, and some drugs have certain side effects on the eyes.
In response, scholastic researchers at the University of California, Los Angeles, created a new drug delivery system that embeds nanodiamonds into contact lenses. In addition, in order to ensure the smooth application of the drug to the eye, the researchers combined the common drugs for the treatment of glaucoma, timolol and maleate, with nanodiamond.
The researchers found that when timolol is in contact with a large amount of lysozyme in the tears, timolol is released and acts on the eyeball. As a result, the researchers say the new treatment is good for drug delivery, and that diamonds can make contact lenses more durable in delivering drugs. The results confirm that this method can reduce certain side effects compared to traditional methods for treating glaucoma.
