If you’re suffering from astigmatism, one route you may take to correct it is undergoing PRK (photorefractive keratectomy) vision correction surgery. This procedure is commonly used to treat nearsightedness and farsightedness, but it can also be effective in correcting astigmatism. So, what should you expect when undergoing PRK vision correction?
How Does PRK Vision Correction Work?
To understand how PRK vision correction works, it’s important to first understand what astigmatism is. Astigmatism is a very common condition in which the shape of the eye’s cornea or lens is shaped abnormally. As a result, incoming light can’t focus correctly on the retina, which can cause issues like blurry vision, trouble seeing at night, and eye strain.
In most cases, astigmatism can be treated with special glasses or contact lenses. However, if you’re looking for a permanent solution, it will require the shape of your cornea or lens to be corrected. During PRK vision correction surgery, the surgeon begins by removing the thin, outer layer of the cornea. After that, they use a specialized laser to carefully adjust the cornea’s shape, which greatly reduces or completely eliminates the effects of astigmatism.
What Should You Expect During PRK Vision Correction?
When you decide to undergo PRK vision correction surgery, your eye surgeon will first examine your eyes to ensure that the procedure is the right option. You will then undergo a process called corneal mapping, which measures the contours of your eyes and helps your surgeon create an effective treatment plan.
Typically, PRK vision correction is performed as an outpatient procedure. You won’t be asleep for the surgery, but you will be sedated and kept as comfortable as possible, and your surgeon will use a numbing agent to prevent any pain. During the surgery, you’ll be asked to focus on a specific light while the surgeon looks at your eye under a microscope. They will then carefully reshape your cornea with a laser, but you won’t feel anything happening. All in all, PRK vision correction surgery only takes around 20 minutes to complete.
What Is the Recovery Like?
After your PRK vision correction surgery, you’ll be able to leave the office within an hour or two. Typically, the surgeon will place a special clear lens in the eye, which will essentially serve as a bandage. You’ll need someone to drive you home, and you may also be prescribed anti-inflammatory and/or pain medication. You will likely need to spend a few days resting, but you should be able to return to your normal routine within a week or so.
After the surgery, your vision may be blurry for a few days. It will improve after that, but it could be as long as a month or more before you start noticing the positive effects of the procedure.
What Is the Takeaway?
For anyone seeking a permanent solution to astigmatism, PRK vision correction surgery is an option worth considering. The procedure is quick and simple, and the recovery isn’t particularly bad.
