What are the benefits of LASIK laser eye surgery?

Mr Tariq Ayoub - 16 Mar 2022

If you’re experiencing a refractive error, you may be looking for a permanent solution. Our article covers the disadvantages and benefits of LASIK laser eye surgery. Read now to find out more.

What is LASIK laser eye surgery?

LASIK laser eye surgery is a refractive surgery for vision correction.

Watch our Consultant Ophthalmologist, Mr Tariq Ayoub, describe the aim of laser eye surgery in this short video.


During LASIK surgery, your ophthalmologist (eye specialist) will use lasers to correct any corneal irregularities causing problems with your vision. The cornea is the front surface of your eye. 

With a refractive error, light doesn’t travel through your cornea to focus on your retina as it should. Refractive errors are common, which is why you should keep to regular eye exams to monitor your eye health.

Refractive errors include:

Refractive errors can cause blurry vision, problems focusing while on a computer or reading, glare or halos around bright lights, and eye strain. LASIK laser eye surgery counters these symptoms.

Disadvantages of LASIK surgery

Temporary dry eyes

Due to less tear production, you may experience dry eyes for a few weeks after the procedure. We can counter this with artificial tears in the form of eye drops.

Glares and Halos

Glares and halos can be a temporary side effect of LASIK laser eye surgery, though they often last a few days up to a few weeks.

It isn’t suitable for everyone

LASIK surgery may not be suitable for people who already suffer from dry eyes, though this will depend on what is causing your dry eyes. Watch our video to learn more: Can I have laser eye surgery with dry eyes?

You may also be unsuitable if you are pregnant, nursing, have advanced glaucoma or poorly controlled diabetes. To ensure a stable prescription, we do not offer LASIK laser eye surgery to people under 21 at Oculase.

Risk of flap complications

Flap complications are rare but can include:

  • Dislocation
  • Folds or wrinkles
  • Epithelial ingrowth
  • Irregular astigmatism
  • Inflammation under the flap

These complications can cause blurry, distorted or double vision. Speak to your ophthalmologist if you experience any of these symptoms after surgery.

Generally, laser eye surgeries, including LASIK, are safe procedures with few complications. Read our blog, ‘Is laser vision correction surgery safe?’ to learn more about the potential risks of this surgery.

Benefits of LASIK laser eye surgery

Fast improvement in your vision

You should see results immediately after the procedure, though your eyes may be blurry or dry for a short time. Over 24-48 hours, you should see significant improvement in your vision.

Quick recovery time

Discomfort in your eyes should only last a couple of hours after the surgery, and other side effects, such as dry eyes and blurry vision, are usually temporary. There is usually no need for bandages or stitches after LASIK eye surgery.

High success rate

LASIK laser eye surgery is very effective, with more than 90% of patients attaining 20/20 vision. Most of the time, you will not need glasses or contact lenses after the LASIK procedure. 

However, with age, you may experience changes in the shape or length of your eye, which can slightly affect your vision quality.

No pain

We use numbing eye drops before the procedure to prevent any pain, though your eyes may feel uncomfortable after the procedure.

Further adjustments

If your eye shape or length changes as you age, affecting your vision quality, LASIK surgery allows the option to re-operate on your eyes to fix these later issues.
