Photorefractive keratectomy

If you are experiencing vision problems such as myopia, hyperopia or astigmatism, you may be a candidate for photorefractive keratectomy (PRK). This procedure is typically used to correct vision issues caused by the shape of the cornea. The most common conditions treated with PRK are:

• Short-sightedness (also known as nearsightedness or myopia)
• Long-sightedness (also known as farsightedness or hyperopia)
• Astigmatism

If you are experiencing any of these symptoms, a private photorefractive keratectomy treatment may be the solution for you. Remember, early detection and treatment can help prevent more serious vision problems in the future. Don't wait until it's too late - book your consultation today.

When you come to Circle Health Group for your initial consultation about a photorefractive keratectomy, we'll start by asking you about your medical history and your reasons for considering the treatment. We'll carry out a comprehensive eye examination to check your eye health and assess your suitability for photorefractive keratectomy. This examination will include measuring the shape of your cornea, testing your vision and checking the overall health of your eye.

Depending on the results of this examination, we may need to carry out additional tests or scans to make a more accurate diagnosis. We'll explain these tests to you in detail and ensure that you're fully informed about what's involved.

Your first consultation is an essential part of the process as it allows us to tailor the treatment to your individual needs. We'll discuss all of the available treatment options with you and make sure you're comfortable with the process. We understand that every patient is different, and we'll take the time to answer any questions you may have and provide you with all of the information you need to make an informed decision.

Our experienced consultants will make a recommendation for the best treatment for you based on the results of your eye examination and other tests, and we'll create a personalised treatment plan that takes your specific needs into account. Rest assured, we'll be with you every step of the way, ensuring you have a positive experience and the best possible outcome.

During your photorefractive keratectomy (PRK) procedure, your surgeon will use a laser to reshape your cornea, allowing your eye to focus more effectively. Here's what you can expect during the procedure:

How long does it typically take?

The entire PRK procedure typically takes around 15 minutes per eye. However, you can expect to spend a few hours at the clinic on the day of the procedure, as you'll need time for pre-operative and post-operative checks.

What anaesthetic is used?

Your surgeon will use eye drops to numb your eye before the procedure. You'll be awake during the procedure, but your eye will be completely numb, so you won't feel pain.

What actually happens during the procedure?

Your surgeon will start by gently removing the thin outer layer of cells on your cornea. Then, they'll use an excimer laser to reshape your cornea, allowing it to focus light more accurately. The laser will be programmed to reshape your cornea based on your specific prescription.

Is there anything you should know about recovery?

After your PRK procedure, you'll need to rest for a few hours. You may experience some discomfort, and your vision may be blurry or hazy for a few days. You'll need to avoid driving and work for a few days, and you'll need to attend several follow-up appointments with your surgeon to monitor your recovery. It may take several weeks for your vision to fully stabilise, and you may need to wear a special contact lens to aid healing.

Remember, your surgeon will provide you with detailed instructions on how to prepare for your PRK procedure and how to care for your eyes during the recovery period. Follow their advice carefully to ensure the best possible outcome.

Like all surgical procedures, photorefractive keratectomy carries some risks. These can include:

• Under-correction or over-correction of the refractive error being treated
• Regrowth of epithelial tissue over the treated area
• Haze or scarring on the surface of the cornea
• Dry eye syndrome or other vision disturbances
• Infection or inflammation of the eye

It's important to note that the risks associated with photorefractive keratectomy are generally low, and most people who undergo the procedure experience few complications.

If you're considering a photorefractive keratectomy, it's important to talk to an experienced eye surgeon who can assess your individual needs and provide you with detailed information about the potential risks and benefits of the procedure. At Circle Health Group, our consultants will take the time to explain everything you need to know about photorefractive keratectomy, answer any questions you may have, and help you make an informed decision about your eye health.

If you're considering photorefractive keratectomy treatment, you may have some questions about the procedure. Here are some frequently asked questions that may help you to understand the treatment better.

What is a photorefractive keratectomy?

Photorefractive keratectomy (PRK) is a type of laser eye surgery that is used to correct vision problems. The procedure uses a laser to reshape the cornea, the clear front part of the eye, to improve how light enters the eye and is focused on the retina. PRK is commonly used to treat nearsightedness, farsightedness, and astigmatism.

What is wavefront-guided photorefractive keratectomy?

Wavefront-guided photorefractive keratectomy (WG-PRK) is a variation of PRK that uses a three-dimensional mapping of the eye to guide the laser during surgery. This technology provides a more detailed and personalised treatment, and can help to correct higher-order aberrations in the eye that traditional PRK may not address. WG-PRK may be recommended for patients with more complex vision problems or who have had previous eye surgeries.

Keep in mind that the best way to determine if photorefractive keratectomy is right for you is to schedule a consultation with a qualified eye surgeon. They will be able to assess your individual needs and provide personalised recommendations.
