Laser eye surgery for astigmatism
In a normal eye, the cornea is shaped so that light rays are highly collimated and directed towards the sharpest point of vision (focus).
In the case of astigmatism, there are different radii of curvature in the two main axes of the cornea. This results in an uncontrolled increased refractive power along certain visual axes. This leads to the perception of distorted images. Objects are often seen twice or with a shadow next to them.
Using laser eye treatment, we can flatten or increase this axis to correct the vision.
