LASEK (laser-assisted subepithelial keratectomy) and PRK (photorefractive keratectomy) are types of advanced laser eye surgery. These treatments can be used to treat conditions like:  

At Oculase, we specialise in personalised, consultant-led treatment with one of London’s top laser eye surgeons, Mr Tariq Ayoub. We blend holistic treatment with traditional procedures so you can get the most out of your treatment journey and achieve better vision. 

Read on to learn more about LASEK and PRK laser eye surgery, what they involve and the benefits of each treatment option.   

What is LASEK? 

LASEK involves using one laser to correct your vision. It may be a suitable option if you have thinner corneas, higher prescriptions for short-sightedness or a pre-existing medical condition that can make laser eye surgery more challenging.

During this procedure, the cornea’s outer layer (epithelium) is first softened and removed with alcohol. This enables the laser to access the cornea’s inner layers and reshape it, correcting your vision.

What is PRK? 

PRK is another common type of laser vision correction. In PRK, the laser reshapes your cornea to correct your prescription.

Trans-PRK is a form of PRK surgery in which the same laser is used to remove both the epithelium and the inner layers of the cornea, called the stroma, to reshape it. This technique is often described as non-touch. At Oculase, we prefer to use this technique rather than LASEK.

LASEK/Trans-PRK procedure


We will provide advice on preparation before your procedure, which will depend on your condition and circumstances. In general, you may be instructed to:   

  • Stop wearing contact lenses and wear your glasses instead for 2 weeks before surgery.
  • Stop using eye makeup, lotions or creams for three days before and on the day of the surgery.
  • Take a shower and wear clean and comfortable clothes on the day of the surgery. We usually advise you not to shower for 2-3 days after the surgery.
  • Eat a light meal on the day of the surgery.
  • Arrange for someone to drive you back home, as your vision may be temporarily blurry after the surgery.
  • Bring UV-protective sunglasses to wear after the surgery to help reduce any photosensitivity (sensitivity to light).   

If you have any questions before the procedure, our specialists are here to help and reassure you.  


During the procedure, your eyes will be kept open with the help of specially designed clips (eyelid speculum) to ensure you don’t blink during the procedure. The laser machine is also programmed to stop immediately when there is movement, so if you do blink or sneeze, for example, you will be safe.

After the surgery, a bandage contact lens is applied to your eye and is usually removed after 4-7 days.  

We will also give you specific aftercare advice, which can include:  

  • Use your eye drops as prescribed. For the first few days after surgery, you may need someone to help you with the drops.
  • Do not take a shower or wash your hair to avoid getting any water into your eyes until your bandage contact lens is removed. However, you can take a bath.
  • Avoid driving until your doctor tells you it is okay to do so.
  • Wear your UV-protective sunglasses for the first few days after surgery and every time you are out in bright sunlight for at least six months after surgery.
  • Avoid wearing eye makeup for one week after the surgery to reduce the risk of infection.
  • Avoid swimming or heavy exercise for two weeks after the surgery to allow your eyes to heal.
  • Do not touch or rub your eyes for at least two weeks after the surgery, as this can affect the healing process. You may gently dab around your eyelids if needed.   


About 95% of people achieve vision that meets driving standards without glasses within 1 week after surgery. After the initial healing period, you will be able to do most activities without glasses. Your vision will continue to get sharper over several weeks.

No flap is created for these types of laser vision correction procedures, so there are no flap-related risks or complications with LASEK/Trans-PRK.

If you do contact sports or if your job puts you at a higher risk of trauma (like a police officer or army personnel), these procedures may be more suitable.

You may also be able to return to work 4-5 days after your surgery. This is dependent on your job, and we will advise you accordingly.


Safety and side effects  

Most people make an excellent recovery after LASEK or PRK. However, the recovery process is slightly slower than that of LASIK. Usually, there is some pain after the procedure as the surface of the cornea heals, but we will prescribe painkillers to help. The pain generally subsides within 2-3 days after surgery, although it may take longer in some people.  

Visual recovery is also slower during the healing process. Once the pain settles and the eyes have healed, you will be able to see much more clearly. This can take a few days. The vision you will achieve is similar about one week after surgery, regardless of whether you have LASEK, trans-PRK, or LASIK. 

You may experience some temporary side effects. These can include:  

While these side effectsmight seem concerning, most people experience no lasting effects. Modern laser technology has also significantly reduced the risk of them.  

At Oculase, we use the latest laser technology to ensure the best outcomes. If you follow our preparation and aftercare guidance as closely as possible, you can achieve optimal results in the long term.  


LASEK and Trans-PRK are similar procedures. Both involve using one laser and applying it to the cornea without creating a flap for access.  

In comparison, during LASIK eye surgery, a flap is first created in your cornea for access. Two lasers are used to reshape your lens to correct your vision, and then the flap is gently repositioned.  

What are the alternatives to LASEK and PRK laser eye surgery?

Alternative surgical procedures to LASEK and PRK can include LASIK, implantable contact lens surgery (ICL) or lens replacement surgery (RLE).  

ICL or RLE may be recommended for people over 50 or those with extreme prescriptions of myopia, hyperopia, or astigmatism. We will discuss the procedures that will be right for you at your consultation.

    No, it is not a painful procedure, as numbing anaesthetic eye drops are used in both eyes. However, after the procedure, the eyes can be painful for 2-3 days as the epithelium heals. You will be given painkillers and drops to help you with the pain.

    Several factors can determine your suitability for LASEK or PRK.  You may be better suited for PRK rather than LASIK if you have thin corneas. Soldiers, police officers, or athletes, such as boxers, may also be better suited to PRK. This is due to the increased risk of trauma, which may cause flap dislodgement if LASIK is used; in PRK, no flap is created.

    Additionally, you should be 18 years or older with a stable eye prescription. Your corneas need to be healthy, and your eye’s overall health must be generally good.


    Like LASIK, LASEK/PRK results can last for the rest of your life. However, changes can occur naturally due to ageing, and your prescription can partially recur as a result.

    If this does happen, you may be able to have further laser treatment, even if your initial treatment was longer than a decade or two. Your surgeon will tell you which procedure is safest for you.

    This is dependent on factors such as the health of your eye, time between surgical procedures, or corneal thickness. However, generally, you can have LASEK after LASIK treatment if your surgeon recommends it and you need a second round of laser eye surgery. 

    Contact us if you have queries about whether you need additional laser eye surgery, and we can advise you on the best course of action. 

    You may be unsuitable for PRK if you have:  

    • Severe dry eyes 
    • Skin or other diseases that can affect healing 
    • Corneal disease 
    • Keratoconus
    • Advancedglaucoma
    • Cataract affecting vision 
    • Poorly controlled diabetes 
    • Pregnant and breastfeeding women 
    • Extreme glasses prescription  

    If you have any of the above, you may be suitable for an alternate procedure, such as Implantable Contact Lens or RLE. AtOculase, we will discuss the best procedure for you based on your examination findings, your scans and your circumstances.  

    Total blindness, where you cannot even see light, is extremely rare. However, all complications are more likely if you don’t follow the aftercare guidelines.
