PRK surgery is a popular procedure for correcting vision. PRK, or photorefractive keratectomy, means removing the damaged tissue and replacing it with new, healthy tissue.
PRK is a laser procedure that uses infrared light to reshape your cornea – the clear membrane that covers the front of your eye. The laser works by breaking down collagen fibers that hold your corneal tissue together. The laser also breaks up some of the epithelium (the outer layer of cells) that covers the eye, allowing it to heal faster.
The success rate for PRK has increased over the years because of improvements in equipment and techniques, as well as more experience with this kind of surgery by doctors. Today, most patients can see 20/20 after having PRK — or even better than 20/20!
PRK surgery is typically used on people who have significant astigmatism, but it may also be an option for people with mild to moderate nearsightedness or farsightedness. It’s not recommended for people with high myopia (nearsightedness), high hyperopia (farsightedness), or if you wear contact lenses or glasses.
The main risks associated with PRK surgery include:
- Burning sensation or redness around the eye after treatment
- Reduced vision in one eye after treatment
- Problems with your pupil due to exposure to intense light during treatment
PRK is a procedure that uses a laser to remove cataracts instead of removing the lens completely. This way, you will not have to undergo surgery to replace the lens. It is very fast, requires no incisions, and can be done on an outpatient basis.
PRK surgery is not suitable for everyone, but it can be an option if you have certain conditions that make other types of cataract-removal procedures unsuitable. If you want to know if are you the right person for this procedure, don’t hesitate to ask professionals in your city. For example, look for PRK Chicago specialists who provide you with more information.
PRK is a procedure that uses an excimer laser to remove the corneal epithelium. It’s often used to treat dry eye and corneal scarring. The laser is focused on the cornea, which then causes it to be absorbed by the body without causing damage.
What is PRK surgery?
PRK surgery is a type of laser eye surgery that uses a low-level laser to reshape the cornea. The procedure takes only a few minutes and can be performed in an outpatient setting.
The laser used in PRK surgery is called a femtosecond laser, which means it emits light at a very short wavelength — within the range of 10 nanometers to 1 micron. This narrow range makes it possible to target the precise area of your cornea that requires reshaping.
PRK surgery is a type of laser refractive surgery designed to correct nearsightedness and farsightedness in patients who have less than 0.5 D of astigmatism in their eyes. The procedure uses an excimer laser to treat refractive errors, such as myopia (nearsightedness) and hyperopia (farsightedness), which can result from abnormal corneal curvature or irregular astigmatism.
The PRK procedure involves removing the top layer of your eye’s protective surface, known as the epithelium, with an ultraviolet light source called a pulsed-dye laser device. The epithelium has been removed during previous treatments with other types of lasers, but it’s still present on your retina (the light-sensitive tissue at the back of your eye).
Is PRK better than LASIK?
Both PRK and LASIK are fast procedures and painless as they are performed under eye drop anesthesia and, sometimes, relaxing medication. Some mind pressure is felt during both, but there’s no significant pain. Both are safe procedures with a very small complication rate during the surgery.
As PRK doesn’t leave a flap in the cornea as LASIK, it’s generally considered to be a safer procedure than LASIK. If you’re eligible for both LASIK and PRK, then it might make sense to go for PRK instead, as it’s also cheaper.
- The flap created during LASIK can cause complications in case your eye is injured. No flap is created during PRK.
- People with very thin corneas are not eligible for corneal incisions – the central part of the LASIK surgery. As a result, they have to go for PRK surgery.
- PRK is also considered to be better for dry eyes, as we explain below.
- LASIK gives clear vision faster compared to PRK.
But depending on what you’re looking to treat, the answer may change.
PRK or LASIK for dry eyes? Though technically, PRK is not a treatment for dry eyes, and neither is LASIK. But comparing these two procedures, dry eye treatment and PRK go together nicely because there’s no flap in the cornea in PRK surgery. The flap increases the risk of dryness in the eyes by disrupting the nerves around the cornea – at least, that’s what’s thought generally.
LASIK can, therefore, worsen the dry eye situation compared to PRK.
PRK presbyopia treatment is considered to be better than LASIK presbyopia treatment under some circumstances. At the same time, in some cases, you will be recommended to go for LASIK instead.
Both are well-known surgeries for a variety of eye-related complications. Depending on what you need, your ophthalmologist will recommend what’s the better option for you. PRK is the first eye surgery for refractive complications and, incidentally, has been improved significantly more over the years.
Ultimately, it depends on you. Only an ophthalmologist can determine which surgery is better for your eyes, PRK or LASIK. Consult an expert from a leading eyecare provider, such as the Kraff Eye Institute, before making up your mind.
