LASIK is a type of refractive eye surgery used to correct vision problems. Find out more about what it is and what it involves below.

What is LASIK eye surgery?

LASIK (laser-assisted in situ keratomileusis) is a type of laser vision correction procedure. It is the most common type of laser eye surgery. Other options include LASEK (laser-assisted subepithelial keratectomy), Trans-PRK (photorefractive keratectomy) and ReLEx (laser lenticule extraction).

What can LASIK eye surgery correct?

LASIK can be used to correct the following conditions:

  • Myopia (short-sightedness) – a condition in which your ability to see far away is affected
  • Hyperopia (long-sightedness) – a condition in which your ability to see up-close is affected
  • Astigmatism – a rugby ball shaped eyeball that can cause blurry vision
  • Presbyopia – a condition in which your ability to read is affected

If you suffer from any of these refractive errors, speak to one of our consultant ophthalmologists (eye specialists) to discuss whether LASIK surgery may be the right treatment for you. Contact us for more information.

How is LASIK surgery performed?

LASIK eye surgery involves reshaping the cornea (the front surface of your eye). Before deciding on this treatment, we will need to assess your eyes to determine your suitability.

You will have a thorough consultation with one of our specialists to discuss your eye and general health. We also will explain the risks, possible complications and what to expect from the procedure.


Before the treatment

Before we begin, we will need to measure your eye to determine exactly what you need to correct your vision.

Contact lenses change the natural shape of your cornea, so you will need to stop wearing them for a few days to a few weeks before your procedure.

On the day of the surgery, we will place numbing eye drops in your eye before we start.

During the treatment

LASIK eye surgery is a flap-based treatment in which we create a flap that allows a laser to change the shape of your cornea.

After the treatment

You won’t need any bandages after the procedure. We will give you a post-operative assessment, and then you will be able to go home.

You will need to arrange for someone else to drive you home. We also advise to not do any strenuous activities or exercise for the next week, and you shouldn’t swim for two weeks. You should also avoid rubbing your eyes for at least a week.

Recovery is usually quick, and you should see significant results from the procedure within 24 hours. Your eyes may feel a little sore after the procedure, though this is normal.

How long does LASIK surgery last?

Most people who have LASIK surgery will have good to excellent vision for years or decades after their procedure. The procedure has a high satisfaction rate with patients.

People with a higher prescription before surgery may find that their vision quality decreases slightly over time. We call this myopic regression. For these patients, we may recommend a second LASIK surgery. Your ophthalmologist will discuss your risk of this happening when you have your consultation.

Is there an age limit for LASIK eye surgery?

You must be at least over 18 to have LASIK eye surgery. At Oculase, we recommend that you are over 21 as you need to have a stable prescription.

After the age of 40, people often develop a condition called presbyopia, which can affect their suitability for this surgery. Presbyopia can be treated with blended-monovision LASIK.

There is no strict upper age limit, but after the age of 55, we may recommend a lens-based treatment, such as refractive lens exchange.

Is LASIK eye surgery safe?

We consider LASIK surgery to be a safe, pain-free procedure. LASIK has a low complication rate, and its side effects usually are uncommon and temporary.

Side effects of LASIK surgery

  • Temporary dry eyes after the procedure. We will provide eye drops (artificial tears) to counter this.
  • Glares or halos at night
  • Sensitivity to light immediately after the procedure
  • Small bruises on your eyes
  • Risk of flap problems
  • Vision loss. This is a rare side effect of LASIK, with severe vision loss being very rare.

Your ophthalmologist will discuss the possible risks before your procedure and will inform you of the likelihood of each, given your circumstances.

    Suitability is dependent on:

    • Your glasses prescription
    • Your eye examination
    • Results of eye scans performed at your consultation
    • Thickness of your cornea
    • Your lifestyle
    • Your work and hobbies

    During your consultation, our specialists will discuss whether LASIK or Trans-PRK is suitable for you depending on your personal circumstances.

    After your consultation, our specialists will discuss your treatment options with you. If you are not suitable for laser eye surgery, we may suggest alternative options to help your vision problems.

    Implantable contacts can be a good option for people who are too nearsighted to qualify for LASIK.

    The surgery is generally pain-free as anaesthesia in the form of drops is used during the surgery to numb the eye.

    After Trans-PRK/LASEK, the eyes may be painful for 2-3 days after surgery. However, you will be given drops and tablets to alleviate any pain.

    Driving can be resumed when the legal standard is met, typically one week after surgery. Our consultants will discuss your personal circumstances with you during your consultation.

    It can take up to three months to recover fully from laser eye surgery and to be able to return to all sporting activities, especially contact sports. You will have several follow up appointments in that time to ensure you get the best results.

    Here’s a quick guide to when you can resume specific fitness activities after laser eye surgery:

    • Jogging – 1 week
    • Aerobic exercise – 1 week
    • Yoga/pilates – 1 week
    • Weightlifting – 2 weeks
    • Sauna/steam room – 1 month
    • Swimming – 1 month
