Korean researchers developed a contact lense that can treat Glaucoma


Glaucoma is an eye disease linked to loss
of vision. Eye-drops and surgical techniques have long
been the main treatments used to slow its progress. Recently however, Korean researchers have
found a more efficient solution. Kim Mok-yeon reports. The National Research Foundation of Korea
announced that local researchers have developed a contact lens that can be used as an efficient
treatment for Glaucoma. The research team, led by professor Kwon In-chan
at the Gwangju Institute of Science and Technology developed a contact lens that boosts drug
delivery efficiency to the eyes, by adding vitamins to soft contact lenses. Since eye-drops don’t stay in the eyes and
are easily washed away by tears, researchers developed this special contact lens that contains
the treatment drugs for Glaucoma. The basic principle is that a soft contact
lens absorbs and stores a special type of drug that cures glaucoma, and when the lens
is worn, the drug is released slowly and more directly to the surface of the eyeball. The team increased the effectiveness of the
lens by adding fat-soluble vitamin A and vitamin E which together form a concrete surface that
can absorb and store larger amounts of glaucoma medication, making it possible for the treatment
to stay in the eyes for a longer period of time. “By using vitamins to store larger amounts
of drugs in the lens, we can also significantly lower the manufacturing cost.” The latest technology is expected to lower
the cost of glaucoma medication because inserting vitamins in the lens is much cheaper than
putting in nanoparticles that can increase drug absorption. Kim Mok-yeon, Arirang News.
