Prk Eye Surgery
PRK (photorefractive keratectomy) is a type of laser eye surgery that is used to correct vision problems such as nearsightedness, farsightedness, and astigmatism.
Unlike LASIK, which involves creating a flap in the cornea, PRK involves removing the outer layer of the cornea (epithelium) before reshaping the cornea with a laser.
PRK was the first type of laser eye surgery to be approved by the FDA, and it has been performed for over 30 years.
This article is your ultimate guide to understanding PRK eye surgery, covering its definition, benefits, procedure, recovery, potential risks, and more.
What is PRK Eye Surgery
PRK works by reshaping the cornea, the clear front part of the eye. The cornea is responsible for focusing light onto the retina, the light-sensitive tissue at the back of the eye. When the cornea is misshapen, it can cause blurry vision.
During PRK, a laser is used to remove a thin layer of tissue from the cornea. This allows the cornea to reshape itself and focus light more accurately.

Who is a Good Candidate for PRK
PRK is a good option for people who have nearsightedness, farsightedness, or astigmatism. It is also a good option for people who are not good candidates for LASIK, a different type of laser eye surgery.
In general, good candidates for PRK are:
- Aged 18 or older
- Have stable vision for at least 1 year
- Have a healthy cornea
- Do not have any eye diseases such as glaucoma or retinal detachment
How Does PRK Eye Surgery Work
PRK is typically performed on an outpatient basis. The procedure takes about 15 minutes per eye.
The first step in PRK is to numb the eye with drops. Then, the surgeon uses a special instrument to remove a thin layer of tissue from the cornea. This is called the epithelium.
Once the epithelium is removed, the surgeon uses a laser to reshape the cornea. The laser is guided by a computer that has been programmed with information about the patient’s eye.
After the laser treatment, a bandage contact lens is placed over the eye to protect it and promote healing.
Benefits of PRK Eye Surgery
PRK has several benefits, including:
- Improved vision
- Reduced dependence on glasses or contact lenses
- Fewer eye complications
In most cases, PRK can provide significant improvement in vision. After PRK, many people are able to see 20/20 or better without glasses or contact lenses.
PRK also has a lower risk of eye complications than some other types of laser eye surgery, such as LASIK. This is because PRK does not involve creating a flap in the cornea.
Risks of PRK Eye Surgery
There are some risks associated with PRK, including:
- Dry eye
- Sensitivity to light
- Complications from the Procedure
Dry eye is a common side effect of PRK. This is because the epithelium, which helps to protect the cornea, is removed during the procedure. Dry eye can be managed with artificial tears or other medications.
Sensitivity to light is another common side effect of PRK. This is because the cornea is more sensitive to light after the procedure. Sensitivity to light usually improves over time.
Pain is usually mild and can be managed with over-the-counter pain medication.
In rare cases, there may be complications from the procedure, such as infection or scarring. These complications are usually treatable.
Recovery from PRK Eye Surgery
Recovery from PRK takes several weeks. During the first few days, the eye will be very sensitive to light. You will need to wear sunglasses or a hat when you go outside.
You may also experience some pain and discomfort. The bandage contact lens will usually be removed after 1-2 days.
After the contact lens is removed, you will need to wear glasses or sunglasses to protect your eyes from the sun.
Your vision will continue to improve over the next few weeks. Most people are able to see well enough to drive and return to work within 1-2 weeks. However, it may take up to 6 months for your vision to fully recover
Prk Eye Surgery Insurance Coverage
The cost of PRK Eye Surgery varies depending on a number of factors, including the surgeon’s experience, the location of the surgery, and the severity of the vision problem.
Insurance coverage for PRK Eye Surgery also varies, with some insurance plans covering the procedure and others not.

Choosing a Surgeon
Choosing a qualified surgeon is one of the most important factors in ensuring a successful PRK Eye Surgery.
Patients should look for a surgeon who is experienced in performing PRK and who has a good reputation in the field.
Patients should also ask the surgeon questions about the procedure and what to expect during the recovery period.
In conclusion, Eye Surgery is a safe and effective way to correct vision problems such as nearsightedness, farsightedness, and astigmatism.
By choosing a qualified surgeon and following post-operative care instructions, patients can minimize the risks and complications associated with the procedure.
With proper care, most people achieve excellent long-term results from Eye Surgery.
