IS LASIK SAFE?
Results vary from centre to centre, but around 90% of people who undergo laser eye surgery have vision between 20/20 and 20/40 (without glasses or contact lenses).

20/20 vision is normal, healthy vision — not “perfect” vision. With 20/40, you can see at 20 feet what an average person sees at 40 feet.

Studies have shown that an average of 95% of individuals who have had laser eye surgery are satisfied with the results.

WHAT ARE THE POTENTIAL SIDE EFFECTS OF LASIK

Glare, halos & double vision
You might notice increased light sensitivity, glare, halos around bright lights or double vision. Your vision in dim light (such as dusk or fog) may be reduced. You may also have difficulty seeing at night after surgery, which usually lasts a few days to a few weeks.


Dry eyes
Dry Eyes are a common side effect of LASIK surgery, which sometimes resolves on its own within a few weeks or months. After the surgery, the cornea may be temporarily weakened. This can cause the eyes to produce fewer tears, leading to dry eyes. In some cases, dry eye after laser eye surgery may be more severe and require treatment. This can include using artificial tears (Drops & Sprays) to moisten the eyes or taking other steps to stimulate tear production (including dietary supplements).


Under-corrections
Under-corrections are more common for short-sighted people. If the laser removes too little tissue from your eye, you won’t get the clearer vision results you were hoping for. You may need another procedure within a year.


Over-corrections
Over-corrections may be more challenging to fix than under-corrections. It’s also possible that the laser will remove too much tissue from your eye.


Astigmatism
Astigmatism can be caused by uneven tissue removal. It may require additional surgery, glasses or contact lenses.


Flap problems
Folding back or removing the flap from the front of your eye during surgery can cause complications, including infection and excess tears. The outermost corneal tissue layer may grow abnormally underneath the flap during the healing process.


Regression
Regression is when your vision slowly changes back toward your original prescription. This is a less common complication.


Pain and/or patches
Eye discomfort, pain or sensitivity to light. In some rare cases, tiny red or pink blood patches on the whites of your eyes.


Infection
As with all surgical procedures, there is a small risk of infection.


Vision loss or changes
Rarely, surgical complications can result in loss of vision. Some people also may not see as sharply or clearly as previously.
