PRK Vision Correction
Photorefractive keratectomy, also known as PRK, is a type of eye surgery used to correct many types of vision limitations. Those who suffer from nearsightedness (myopia), farsightedness (hyperopia), or astigmatism may see a significant improvement in their vision after having this type of eye surgery. As one of the first types of laser eye surgery developed, it has been in use much longer than the more popular LASIK procedure. However, it is still used and may offer several key benefits.
What Happens in PRK Eye Surgery?
PRK eye surgery involves reshaping the cornea using a laser. The reshaping process helps properly focus the light that enters the eye onto the retina. This improves and clarifies vision. When you undergo the PRK procedure in our Brooklyn office, the surgeon removes the thin outer layer of the cornea altogether, whereas in LASIK surgery, the surgeon only pulls this tissue back. Once removed, this tissue is discarded; the surgeon then works to correct the shape of the cornea. The outer layer, called the epithelium, grows back on its own over time.
What Can You Expect During the PRK Eye Surgery?
Before the procedure, your eye surgeon will carefully examine your eyes to ensure you are healthy enough for surgery and will benefit from it. You will undergo a process called corneal mapping to measure the contours of your eyes. Using this information, the surgeon will create a plan to follow during the procedure.
PRK eye surgery is generally an outpatient procedure. In most cases, it takes less than 20 minutes to complete. You are not put to sleep for this procedure, but you will be sedated and comfortable. We will also use a numbing agent to ensure that you feel no pain.
We’ll ask you to look at a specific light for a few minutes while we look at your eyes under a microscope. You’ll notice the surgeon’s use of the laser, but you will not feel it. The laser directs pulses of light toward your eye; each pulse changes the shape of your cornea by removing a very small amount of tissue. Your surgeon is completely in control of the process.
What to Expect During Recovery From PRK?
We’ll have you relax in our office for a bit before you leave. We will also provide you with anti-inflammatory medications and pain medications as needed. Someone else will need to drive you home. You can expect to recover at home for a few days; most people feel back to normal within a couple of weeks. It can take some time for your vision to be completely restored and improved.
