LASIK for Astigmatism
Astigmatism is the result of having a corneal surface that is not regular in shape. The eye is unable to focus clearly at any distance because of this irregular focussing surface.
The good news is that astigmatism can be corrected with LASIK eye surgery.
How does LASIK treat Asigmatism?
Astigmatism typically is caused by the front surface of the eye (cornea) having an asymmetrical shape.
An analogy that's often used to describe this is to say the cornea is shaped like an egg or the back of a spoon, rather than like a ping-pong ball.
The ultra-precise lasers used for LASIK surgery can be programmed to reshape the cornea so the front surface of the eye is more symmetrical, thereby eliminating vision problems caused by astigmatism.
For nearsighted people, the goal is to flatten the cornea whilst with farsighted people, a steeper cornea is desired. Excimer lasers correct astigmatism by smoothing an irregular cornea into a more normal shape.
