Eye surgeons have performed over 40 million Laser Eye Surgery procedures worldwide. Some project that Laser Eye Surgery will be commonest surgical procedure in the world (after cataract surgery).
The vast majority of patients achieve outstanding results without complications. Still, Laser Eye Surgery remains a surgical procedure. As with all surgical procedures, there are risks.
The most common Laser Eye Surgery risks include:
Surgical complications relating to the flap during Laser Eye Surgery. The flap might not perfect at the time of surgery. If this is the case, we defer Laser Eye Surgery for three months. The flap may also cause problems if it heals in an unconventional way. We can correct most flap complications can without compromising the visual outcome. With femtosecond Laser Eye Surgery, you needn’t worry about flap complications.
Post-operative dry eye. Some patients need tear drops for a few months after Laser Eye Surgery. It is rare for patients to need tear supplements long term. If we detect you may be at risk for post-operative dry eye, we’ll inform you of this before the Laser Eye Surgery.
Some patients have seen glare and halos around lights at night after Laser Eye Surgery. Night vision disturbances do not usually interfere with driving. Most cases resolve within the first six months after surgery. Laser manufacturers introduced Wavefront technology which reduced the incidence of night vision disturbances.
You can be under or over corrected. Under or over correction occurs when a patient’s individual healing response varies from the average for their age and sex. That is more likely to occur in the correction of higher degrees of short or long sight. It’s important to note that we can retreat patients after their original treatment. We like to wait some time for the eyes to settle after a primary treatment. If the eyes have not resettled after a reasonable amount of time, we’ll offer an enhancement.
Reduction of vision can result following all forms of laser surgery. It’s possible that glasses or contact lenses worn after surgery may not correct it. This problem may be due to inflammation or infection of the cornea after treatment. Vision loss can result from irregular healing or scarring of the cornea.
A severe visual loss is rare (we’ve never had a case where a patient experienced severe visual loss). In extreme cases, patients have required corneal transplants following treatment.
