Astigmatism is one of several common vision problems, but it is a bit different than the others. Whereas most others cause issues with either near or distant vision, astigmatism can cause problems seeing clearly at all distances. Though it can be a lifelong condition, there are ways to address it. Let’s look at this quick guide about astigmatism and treatment options provided by our eye doctors at Granite Pointe Eye Care in Roseville, CA.
What Is Astigmatism?
To have good vision, your cornea needs to be shaped like a sphere. This ensures that the light that enters your eye refracts properly. With astigmatism, the cornea is shaped more like a football. This makes the light that enters the eye focus behind or in front of the retina instead of on it. This causes your vision to become blurry.
In most cases, people are born with this condition. It may not present itself as a problem in your early years, but it can worsen over time. Other people experience astigmatism after an injury or trauma to the cornea. This is typically called irregular astigmatism.
Astigmatism Treatment Options
Some of the common treatment options for astigmatism are the same as other vision issues: prescription eyeglasses or contacts. In most cases, these will only treat regular astigmatism – the kind that you are born with. For irregular astigmatism, rigid gas-permeable contacts are a better option.
Though glasses and contacts can help you see better, they won’t fix the issue. For a permanent solution, refractive surgery is necessary. There are two different types of refractive surgery used to treat astigmatism: LASIK and PRK. LASIK or laser-assisted in situ keratomileusis is the more common option. It involves cutting a thin flap of the cornea and then using a laser to reshape the cornea. Typically, both eyes can be done at once.
PRK or photorefractive keratectomy is less common but sometimes necessary. For LASIK to be done, the cornea has to be thick enough to safely cut the flap. If your cornea is too thin, PRK is required. Since it takes a little longer to heal from PRK, your eye doctor will typically only do one eye at a time.
