Significant advances in the treatment of green cataracts with hydrogel

Georgia: Water-filled hydrogel will now be able to treat complex diseases such as glaucoma, a special type of hydrogel that can open the door to treatment for this difficult disease without any surgery.

In which eye drops and taking medicine can also get rid of.

Scientists at Georgia Tech and Emory University have developed an injection of a very thick hydrogel that contains a water-absorbing polymer. Treatment of cataracts involves first reducing the pressure inside the eye, and in very serious cases irreversible blindness can occur.

Sometimes an operation has to be done to reduce the pressure inside the eye, which sometimes fails. With this technology, a polymer can be inserted into a place under the eye with a needle. The place where this polymer is inserted is called the supercoidal space (SCS).

Inserting the polymer opens a passage in the SCS and from there the fluid that accumulates in the eye comes out. Now, in the new technology, inserting a tiny drop of hydrogel (50 micro liters) into a needle just one millimeter long opens the narrow passage inside the eye.

This process can also open another closed central passage behind the eye, which drains out the fluid that has accumulated inside and reduces the pressure created inside the eye. One injection opens the eye socket for four to five months. In this way, the patient gets relief from the injection twice a year.

Currently, these experiments have been performed on some animals with very encouraging results.
