How does laser eye surgery work?

Laser eye surgery (laser sight correction) involves precise reshaping of the cornea to very accurately correct short sight (myopia), long sight (hyperopia), and astigmatism. At Moorfields Private we offer LASIK and surface laser treatments (PRK, LASEK, and TransPRK).

  • All modern laser eye surgery procedures produce similar visual results. The main difference between the categories outlined below is speed of recovery and time off work.

    Your specialist consultant surgeon will discuss each of the procedures in more detail with you at your first consultation, when they will advise which will best suit your individual needs.

    LASIK

    This is the most commonly performed laser eye treatment. For LASIK surgery, two different types of laser are used. First, a femtosecond laser creates a thin protective layer by tracing a 3D pattern of tiny gas bubbles through the corneal tissue. This hinged layer is lifted back by the surgeon before an excimer laser reshapes the cornea to correct focus. The protective flap is then replaced to complete the procedure.

    After approximately 3-6 hours, the surface cell layer heals around the edge of the flap and sight begins to improve. By the day after surgery, most people are able to see well enough to work and drive a car.

    Surface laser treatment (LASEK and TransPRK)

    Surface laser treatments are performed directly beneath the clear skin layer of the cornea (the corneal epithelium), which is removed by the laser (TransPRK) or the surgeon (LASEK) before laser reshaping to correct vision. Visual recovery is slower than for LASIK eye surgery because it takes the skin layer a few days to grow back and a few weeks to smooth off optically. Surface laser treatments are often the best option for patients with thinner corneas.

    Once the surface cell layer has healed, the vision starts to improve and typically reaches the driving standard in 1-4 weeks after TransPRK or LASEK eye surgery, depending on the prescription treated. Most patients require a week off work after surgery.

  • It may be more affordable than you realise to get laser eye surgery from the highly experienced surgeons at Moorfields Private. Fees for your initial consultation start from £150.

    Once you have agreed a personalised plan with your consultant, the full cost of onward treatment can be confirmed. As a guide, Moorfields laser eye surgery costs start from £4,300, which includes your consultant’s professional fees. Moorfields Private’s refractive surgery costs reflect the highest quality of care and the most advanced refractive laser equipment available.

    Laser eye surgery costs in the UK do vary based on a number of factors. Here are some common factors that can affect your eye laser treatment cost:

    The type of treatment

    We offer a wide range of treatments suited to your needs. Your consultant will be able to advise which type of laser eye surgery is best for you.

    Your chosen consultant

    Moorfields Private’s consultants are renowned world-wide. You can choose your preferred consultant who will deliver every aspect of your care throughout your entire treatment pathway.

    Your TransPRK or LASIK eye surgery cost will usually include post-operative consultations and take-home medication. However, if you wish to see your consultant outside of the covered treatment plan, there may be additional charges which will be advised by your consultant’s practice manager.

    To find out more about laser eye surgery finance with interest free payment plans, please make an enquiry with your chosen consultant’s practice team. Further information on how to pay for your treatment can be found on our payment page.

  • When you choose Moorfields Private for laser eye surgery, you can rest assured that you will receive the highest quality treatment and care. Moorfields Private has a worldwide reputation, with all of our surgeons holding accredited consultant positions at Moorfields Eye Hospital NHS Foundation Trust, working at the very top of their profession.
    They use the most advanced refractive laser equipment available, which is renewed every three years to provide supreme accuracy.

    Above all, we pride ourselves on offering a service with complete continuity. At each visit, you will see the surgeon of your choice who will supervise every aspect of your care from start to finish. We pride ourselves on delivering the best experience and results when it comes to laser eye surgery in the UK.

  • At your first appointment, your specialist consultant surgeon will discuss the most appropriate laser treatment for your eyes to suit your individual needs. However, the following is a useful guide to general suitability:

    • You should be at least 21 years old and your eyes must be healthy and your prescription stable.
    • You should not be pregnant or nursing, as these conditions might change the measured refraction of the eye. You should wait for three months after breastfeeding to come for a consultation.
    • You should not be taking certain prescription drugs, such as Accutane or oral Prednisolone.
    • You should be in good general health. Laser eye surgery may not be recommended for patients with diabetes, rheumatoid arthritis, lupus, glaucoma, herpes infections of the eye, or cataracts. You should discuss this with your surgeon.
    • If you’re long-sighted (can’t see things close up), your prescription should be up to +3 to +4.
    • If you’re short-sighted (can’t see things in the distance), your prescription should be up to -10 to -11.
    • If you have astigmatism (poor near and distance vision), your prescription should be up to -6D.
  • Serious complications following laser eye surgery are rare and Moorfields Private has an excellent safety record. Less than 1 in 5000 patients require further surgery to replace damaged tissue in the cornea - the clear window at the front of the eye.

    Despite these advances, all surgery carries a small risk of complications. Most problems can be fixed and it is important to note that wearing contact lenses – the main alternative to laser vision correction for most patients – is also not free of risk, with approximately 1 in 3000 contact lens wearers developing a serious corneal infection every year.

    Your surgeon will discuss any risks with you before you decide to go ahead with the surgery.

  • Normally, laser eye surgery will leave you with life-long freedom from glasses and contact lenses. However, natural changes in your prescription can occur throughout your lifetime. There are a number of repeat treatment options for patients in any age group who experience changes in their vision following laser eye surgery. Your surgeon will discuss these with you during your consultation.

  • For all types of laser eye surgery, local anaesthetic drops are used to completely numb the patient’s eye. Patients may experience around 30-40 seconds of pressure on their eye during LASIK or SMILE surgery, when the LASIK flap or SMILE lenticule is being created. They may also experience around 4-6 hours of mild discomfort following the surgery.

    If you are nervous about the procedure, you can request to take a sedative tablet.

  • Laser eye surgery is typically a quick procedure, taking around 10-15 minutes for both eyes.

  • It takes around 3-6 hours for the surface cell layer on the eye to start healing and for sight to begin improving following LASIK eye surgery. Most people are able to drive and return to work the day after their surgery.

    LASEK and TransPRK surgeries have a longer recovery time, with patients taking around 1-4 weeks for their vision to return to driving standard after the procedure. Most people require a week to recover before returning to work from this type of surgery.

  • The only way to know which vision correction treatment is the right option for you is by booking an appointment with one of our specialist consultant eye surgeons. Here are the next steps to take towards better vision:

    3. After you’ve met with your consultant and been assessed, we will book the surgery.
    4. Surgery takes around 10-15 minutes for both eyes.
    5. One to three days later, you will have a follow-up appointment to check how your eyes are recovering.
