Astigmatism is a condition where the cornea has an irregular shape that causes problems with vision. The cornea, the clear covering of the lens and iris, serves as a protection to the eye and helps transmit light through the eye. The cornea is normally spherical in shape, but those with astigmatism may have their cornea more oval shaped. This oval shaping causes light to scatter instead of focusing to a single point as it passes through the cornea and results in blurred vision.
LASIK Surgery for Astigmatism
A common misconception is that LASIK eye surgery doesn’t apply to astigmatism, but that’s false.
LASIK eye surgery is by far the most commonly selected procedure for refractive eye surgery. During the LASIK procedure, a small incision creates a corneal flap and an excimer laser is used to reshape the cornea. The excimer laser is different from other lasers in that it doesn’t produce heat. Once the procedure has been completed, the corneal flap is repositioned normally and the healing process begins. Most people can notice quite an improvement in vision immediately upon completion of the procedure.
As was answered in your first question, astigmatism isn’t a disease , so it isn’t something to be " cured"
It is just the way light is entering your cornea at 2 different focal points which doesn’t allow the light to focus right on your retina in a single straight line.
That has to do with the shape of your cornea, so there is nothing that can be done about it, unless you undergo laser surgery eventually.
Also, as I said before, about 80% of eyeglass wearers have some astigmatism , it isn’t a big deal, and is easily corrected ( not cured) with glasses.
Astigmatism is more of the "football" shape on the cornea, like nearsightedness is too steep of a curve, or an elongated eye. That is why lenses correct, or lasik removes the corneal tissue that is not curved. Contacts that correct astigmatism have to match the axis of the astigmatism. That is why when the lens turns or moves, your eyes get blurry.
cant cure it but you can treat it, its caused by genetics . Both glasses and contacts all those help but they have to be special made. I have astigmatism, if your like me and its only to a small degree you can wear regular contacts and glasses and wont affect vision much. But if the astigmatism is of a higher degree you will need special made contacts and i think acuvue makes a mass produced one called acuvue with astigmatism.
