Myths and facts about laser eye surgery

Success rates of laser eye surgery

Before having laser eye surgery, people have many questions. One of the most frequently asked questions is ‘will I go blind?’.

Millions of people worldwide have had laser eye surgery since its introduction in 1989. Today, it is accepted that 90% of patients worldwide who have had a vision correction procedure will have perfect results – up to 98% of patients are able to drive legally without glasses or contact lenses after their procedures.

Are there possible complications after a laser vision correction procedure?

The aim of laser eye surgery is to correct a person’s vision – whether they are short-sighted, long-sighted or have astigmatism – by reshaping the cornea. It is extremely rare that a post-operative complication cannot be corrected.

In some cases (1–5%), a patient’s refractive error may be under- or over-corrected. This will be apparent in the first few months and can usually be fixed by a second surgical procedure (at no extra cost to the patient).

Other possible complications include:

  • Flap problems. This involves a misalignment of the ‘flap’ created on the corneal surface during LASIK, and is usually caused by a patient rubbing their eyes, swimming or taking part in contact sport too soon after the procedure.
  • Loss of visual sharpness. Approximately 1–2% of people may experience this. It usually returns to normal within 6 months.
  • Infection. This is highly unlikely when laser eye surgery is performed by respected surgeon in a reputable clinic.


The vast majority (up to 99%) of people who have had a laser vision correction procedure are extremely happy with their outcome. 98% of people can drive legally without the use of glasses or contact lenses the day after surgery.

As laser technology advances and surgeons perform more of these procedures, the risks decrease. Certainly, this is why it’s recommended that people seek out the most experienced eye surgeons who work with the most up-to-date technology.
