Most people are aware of long-sightedness and short-sightedness. But not everyone knows about astigmatism. Approximately 1.4 million Australians struggle with this vision defect. It may also be present alongside shortsightedness, but not always.
What causes this refractive error? What are the symptoms? Can you get refractive surgery for astigmatism? Let’s find out!
What is astigmatism?
The ideal eye should be round. Unfortunately, most of us do not have perfect eyes. In reality, most people have an eye with astigmatism to some degree or another.
When the eyeball isn’t round, the cornea bends the light passing through at odd angles. This means the light will not fall on the focal point in the eye. This causes blurry and distorted vision of objects at all distances. This may cause eyestrain and headaches for some people. Astigmatism symptoms can be more obvious at night, causing halos around light rays.
Most people are born with astigmatism. Although, it is possible to develop the problem after eye surgery, injury, or eye disease.
How can you fix astigmatism?
You can wear eyeglasses or contact lenses to correct the issue. But, if you dislike the idea of wearing corrective lenses for the rest of your life, you can have laser eye surgery.
In laser eye surgery, we remove small amounts of the front surface of the cornea to give it the correct curvature. This ensures that it bends light in such a way that it falls on the correct point, so your vision is clear.
It is not necessary to be long-sighted or short-sighted to have surgery. You can have surgical procedures to correct astigmatism even if that is your only vision defect. The cost of this surgery is the same as for any other type of laser eye surgery.
If you have astigmatism and cataracts, we can correct both at the same time with a lens implant.
