Researchers turn to ultrasound to restore vision, targeting lens, retina, and cornea

New Delhi: Scientists are exploring ultrasound as a new tool to restore vision, taking advantage of the eye’s easy access to sound waves.

The lens, cornea, retina, and vitreous humor can all be studied and targeted using ultrasound, researchers say. Because ultrasound travels as a mechanical wave and forms detailed images without ionizing radiation, it offers a safe way to examine delicate eye structures.

Recent work is moving beyond imaging. Teams are testing ultrasound to deliver drugs to the retina, stimulate nerve cells, and even treat conditions like glaucoma and retinal degeneration by using focused sound energy.

Unlike X-rays, ultrasound poses no DNA damage risk, making it suitable for repeated use in sensitive organs like the eye. Experts say its ability to distinguish tissues of different stiffness could help map damage and guide non-invasive therapies.

While still in early stages, the approach signals a shift: from using ultrasound just to look at the eye, to using it to heal.
