Cataract is a condition in which the crystalline lens in the eye becomes clouded and prevents light from easily passing through. It ultimately leads to vision loss, therefore it must be treated in order to prevent the possibility of blinding. With new technology, Tamela Martin, MD describes how the treatment has advanced. Phacoemulsification, which is high frequency sound waves, is a procedure that has helped in treatment to make incisions in the eye and remove the cataract with a vacuum like device. A lens is then placed in the eye. Though technology has advanced, the results still aren’t drastically different and there are still risks involved.
