Scientists develop eye drops that can dissolve cataracts—it could be the answer to vision problems


There are more than 285 million people worldwide who have vision problems and 32.4 million people around the world estimated by Fred Hollows Foundation to be blind. 90% of these people live in developing countries with more than half of these blindness cases are caused by cataracts.

According to the American Academy of Ophthalmology, nearly 22 million Americans who are over age 40 have cataracts and more than half of Americans will have cataracts by the time they reach 80.

As the leading cause of blindness in the world, FOM reported that the only treatment to cataracts is only surgery—and it’s expensive. Hence, treatment is not an option for not only those in developing countries but many others too.

As cataracts form a milky layer over the eye which obstructs vision, the treatment was created based on a naturally-occurring steroid known as lanosterol.

Scientist initially discovered two siblings who had cataract but not their parents. They thought maybe the parents don’t have cataracts because they are producing lanosterol and their kids have cataracts because they aren’t producing lanosterol. Scientist tested this hypothesis on rabbits and the results were very promising.

Due to this, researchers based in the US have created a drug that can dissolve cataracts and can be delivered directly into the eyes through an eyedropper.

However, the treatment has yet to be tested on humans. If the trials on human are successful and they make it to the market, these eye drops could change the lives of millions around the world.

Hopefully, the trial will be successful and it will be available to the public very soon!
