PRK Eye Surgery

A proven surface laser treatment for clearer vision

PRK is a well-established form of surface laser eye surgery that can suit patients with thinner corneas, higher prescriptions, or for some people whose occupation, sport or lifestyle makes a flap-free procedure preferable.

It corrects short-sightedness, long-sightedness and astigmatism by reshaping the cornea with an excimer laser. Unlike LASIK, however, no corneal flap is created.

Recovery can take up to five days, and the early healing period can be uncomfortable. It is normal for patients to experience light sensitivity, discomfort, and grittiness during this period. We advise patients to rest and avoid screens. For suitable patients, PRK offers an established route to long-term vision correction using a flap-free approach.

PRK eye surgery: a flap-free laser eye surgery option

PRK is a surface laser eye surgery procedure designed to correct your prescription without creating a corneal flap.

It can be particularly suitable for patients with thinner corneas, higher prescriptions and certain occupational requirements, or active lifestyles involving contact sports.

The treatment works by reshaping the cornea with laser technology so light can focus more accurately inside the eye. Because the correction is performed on the surface of the cornea, the eye needs several days to heal initially.

Your consultation is designed to establish which type of laser eye surgery is most appropriate for your individual eyes.

What is PRK eye surgery?

PRK stands for Photorefractive Keratectomy. It is a type of surface laser eye surgery used to correct refractive errors such as short-sightedness, long-sightedness and astigmatism.

During PRK, the thin outer layer of cells covering the cornea, called the epithelium, is prepared so that an excimer laser can reshape the corneal tissue beneath. Once treatment is complete, a protective contact lens is placed over the eye while the surface heals.

How PRK compares to LASIK

PRK is not a lesser alternative to LASIK. For the right eyes it is the more suitable choice, and long-term results are comparable.

What happens during PRK eye surgery?

The PRK procedure involves five main steps.

  • 01

    Anaesthetic drops

    Anaesthetic eye drops are applied before treatment to numb the surface of your eye. You remain awake during the procedure, but the drops help keep the eye comfortable while your clinical team explains what is happening.

  • 02

    The epithelium is gently prepared

    With Optilase's PRK surface treatment, the outer layer of cells on the cornea, the epithelium, is softened using an ethanol solution and gently moved aside. This gives your surgeon access to the corneal surface that needs to be reshaped.

  • 03

    Laser reshaping

    An excimer laser is then applied to the cornea to correct your prescription. The laser removes microscopic amounts of tissue to alter the shape of the cornea so light can focus more accurately inside the eye. Where suitable, treatment can be guided by i-Design Advanced Wavefront Technology to create a more personalised treatment profile.

  • 04

    A protective contact lens is applied

    Once laser treatment is complete, a special contact lens is placed over the cornea. This acts as a temporary protective layer while the surface cells heal. It is normally worn for approximately five days and removed by your clinical team when appropriate. You can return home on the same day.

  • 05

    Protective lens removal and early recovery

    The protective contact lens is normally worn for approximately five days while the epithelial surface heals. Your clinical team will check your eyes and remove the lens when appropriate. Vision usually continues to improve gradually after the lens is removed as the cornea continues to heal and settle.

Your free PRK consultation

Your free consultation with an Optilase laser optometrist takes approximately one hour and allows us to examine your prescription, corneal health and overall suitability for laser eye surgery.

  • A discussion about your vision and prescription history
  • Assessment of your eye health and detailed vision testing
  • Measurement of your corneal shape and thickness
  • Advanced corneal mapping
  • i-Design scanning where appropriate
  • Assessment of your suitability for PRK or another procedure
  • Discussion of your work, sport and lifestyle
  • An explanation of the treatment recommended for you
  • Clear information about PRK recovery time
  • Discussion of potential risks and side effects
  • Information about treatment costs and finance options
  • Time to ask questions before deciding whether to proceed

The decision about whether PRK or another vision correction procedure is suitable should be based on your individual eyes rather than personal preference alone.

Preparing for PRK eye surgery

Your clinical team will give you personalised instructions before surgery. These may include stopping contact lens wear for a specified period before treatment, using lubricant drops to improve corneal health and avoiding eye make-up for 24 hours before your procedure. We will also explain what to expect during the first week of recovery so that you can plan work, driving and other activities realistically.

Who is suitable for PRK?

PRK may be recommended when surface laser treatment is considered appropriate for your individual eyes. You may be suitable if you:

  • Are aged 18 or over
  • Have a stable prescription
  • Have healthy eyes
  • Have a prescription within the treatable range
  • Have corneal measurements that may make a flap-free surface treatment more appropriate
  • Participate in certain contact sports
  • Work in an occupation where avoiding a corneal flap may be preferable

Prescription strength, corneal shape and overall eye health will also affect your suitability. Some patients will be better suited to another form of vision correction entirely. Your laser optometrist and consultant ophthalmic surgeon will advise you based on your individual assessment.

Your PRK recovery, week by week

Because PRK treats the surface of the cornea, healing follows a predictable pattern. Your clinical team will give you personalised guidance at every stage.

  1. Day 0

    Treatment day

    Your procedure takes place under anaesthetic drops. A protective contact lens is fitted before you leave and you go home the same day.

  2. Days 1-5

    The surface heals

    The protective lens stays in place while the epithelium regrows. Rest, avoid screens, and expect discomfort, watering and light sensitivity.

  3. Days 5-7

    Lens removed

    Your clinical team removes the protective lens when the surface has healed. Most patients return to work around this point, depending on their occupation.

  4. Weeks 2-6

    Vision settles

    Vision continues to improve and may fluctuate as the cornea settles. You will attend follow-up appointments so we can monitor healing.

  5. Long term

    Fine improvements continue

    Fine visual improvements can continue for several months, with your results supported by our laser lifetime care guarantee.

Recovery varies from person to person. If anything feels significantly different from what your clinical team has told you to expect, contact the clinic for advice.

What's normal, and when to call us

Some symptoms are an expected part of surface healing. Others are worth a phone call.

Expected while you heal

  • Discomfort
  • A gritty or scratchy sensation
  • Watering
  • Light sensitivity
  • Blurred vision
  • Fluctuating vision
  • Dryness

Contact the clinic if you notice

  • Severe or worsening pain
  • A sudden deterioration in vision
  • An opaque discharge
  • Excessive redness
  • Symptoms that are significantly different from what your team described

These symptoms vary from person to person and generally improve as the surface of the eye heals.

PRK aftercare

Following your aftercare plan carefully helps support your recovery. Your personalised instructions will cover:

  • Prescribed eye drops
  • Caring for the protective contact lens
  • Avoiding rubbing your eyes
  • Driving
  • Returning to work
  • Exercise
  • Contact sports
  • Showering and swimming
  • Eye make-up
  • Screen use
  • Protecting your eyes from bright sunlight

You will also attend follow-up appointments so we can monitor how your eyes are healing. If anything feels significantly different from what your clinical team has told you to expect, contact the clinic for advice.

Dry eyes after PRK surgery

Temporary dry-eye symptoms can occur while the surface of the eye heals after PRK. Symptoms can include:

  • Dryness
  • Grittiness
  • Burning or irritation
  • Fluctuating vision
  • Sensitivity to wind, heating or air conditioning

Lubricating drops will form part of your aftercare plan. For many patients, dryness improves as healing progresses, although recovery varies. Persistent or worsening dry-eye symptoms should be discussed with your clinical team.

PRK eye surgery risks and side effects

PRK is an established laser vision correction procedure, but like all forms of surgery, it has potential risks and side effects.

  • Pain or discomfort during early healing
  • Dry-eye symptoms
  • Light sensitivity
  • Blurred or fluctuating vision
  • Glare or halos around lights
  • Under-correction or over-correction
  • Regression of part of the original prescription
  • Inflammation
  • Infection
  • Corneal haze
  • The possibility of enhancement treatment
  • Rarely, more significant changes to vision

The likelihood of individual complications depends on factors such as your prescription, corneal measurements, eye health and healing response. Your clinical team will explain the risks that apply to you before treatment so you can make an informed decision.

PRK technology at Optilase

Excimer laser technology

PRK laser eye surgery uses an excimer laser to reshape microscopic amounts of corneal tissue according to your treatment plan. By precisely changing the curvature of the cornea, the laser changes how light is focused inside your eye. Optilase uses excimer laser technology with eye-tracking and iris-recognition capabilities designed to support accurate treatment delivery.

i-Design Advanced Wavefront Technology

A standard glasses prescription tells us how much correction your eyes need, but every eye also has its own individual optical characteristics. i-Design Advanced Wavefront Technology provides detailed measurements that can be used to create a more personalised laser treatment profile.

PRK questions answered

Quick answers to the questions we hear most often about PRK at Optilase Eye Clinic.

  • PRK, or Photorefractive Keratectomy, is a surface laser eye surgery used to correct short-sightedness, long-sightedness and astigmatism. The outer surface of the cornea is carefully prepared before an excimer laser reshapes the tissue underneath. A protective contact lens is then placed over the eye while the surface heals.

  • PRK and LASEK are closely related surface laser eye surgery techniques, but they are not exactly the same. With PRK, the epithelial cells on the surface of the cornea are prepared and removed before the excimer laser treatment.

    With LASEK, the epithelial layer is softened and moved aside before laser treatment, then repositioned across the corneal surface afterwards. Both procedures normally use a protective contact lens while the eye surface heals. Optilase offers PRK. Your clinical team can explain the procedure in detail during your consultation.

  • PRK may be recommended when your eye measurements or lifestyle make a surface procedure more suitable. For example, it may be considered for some patients with thinner corneas or people involved in certain contact sports or occupations where avoiding a corneal flap may be preferable. Your consultation will establish which treatment is most appropriate for you.

  • Anaesthetic drops are applied first to numb your eye. The epithelial surface is then prepared so an excimer laser can reshape the cornea and correct your prescription. A protective contact lens is placed over the treated eye afterwards and normally remains in place for approximately five days while the surface heals.

  • The PRK procedure itself is performed using anaesthetic eye drops. The main difference in comfort occurs during recovery. Because the surface of the cornea needs time to heal after PRK, soreness, grittiness, watering and light sensitivity can occur during the first few days. Our team will explain what to expect and how to manage the early recovery period before you have surgery.

  • The surface layer of the cornea generally heals over approximately five days, during which a protective contact lens is normally worn. Patients may need around 5 to 7 days away from work depending on their occupation and individual recovery. Vision then continues to improve and settle during the following weeks.

  • PRK treatment costs can vary depending on the treatment plan and technology recommended for your individual eyes. Your full treatment cost will be explained clearly following your suitability assessment, including what is included in your treatment and aftercare. For current information, visit our laser eye surgery pricing page.

  • PRK is a well-established form of laser eye surgery. However, no surgical procedure is completely without risk. Possible PRK eye surgery risks include infection, inflammation, dry eye, glare, halos, under- or over-correction and corneal haze. Careful assessment before treatment helps identify whether PRK is appropriate for your eyes. Your Consultant Ophthalmic Surgeon will discuss the relevant benefits and risks with you before surgery.
