G7: In Focus: Keratoconus

Keratoconus occurs when your cornea — the clear, dome-shaped front surface of your eye — thins and gradually bulges outward into a cone shape.

Changing the shape of the cornea brings light rays out of focus. As a result, your vision is blurry and distorted, making daily tasks like reading or driving difficult.

In the early stage and in mild keratoconus, eyeglasses may be all that is needed to improve vision

The minimally-invasive therapy slows down or stops the progression of the corneal deformation of keratoconus, by making collagen bonds in the cornea stronger, allowing it to become stiffer and usually stop bulging out.
