What are the risks of laser eye surgery?

Dr Abi Tenen


For more than 30 years, laser eye surgery has been performed around the world to correct refractive errors, including short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. During this time, thousands of clinical studies have shown laser eye surgery to be one of the safest elective procedures available today.

However, all medical and surgical procedures carry some degree of risk, so it’s extremely important to choose a skilled surgeon and a clinic equipped with the latest technology to reduce your chances of complications.

The risk of complications and side-effects are low

Most of the complications and side-effects from laser eye surgery are temporary and they generally resolve on their own or with follow-up treatment. Potential issues to be aware of include:

No patient in Australia has become blind from laser eye surgery

For some patients considering laser eye surgery, their biggest fear is becoming blind as a result of the procedure. Blindness is always listed as a potential side-effect of any eye surgery, but this would usually only result from serious complications inside the eye (e.g. an infection). The reality is that no patient has ever become blind after undergoing laser eye surgery in Australia.

One of the reasons for this is that laser eye surgery is a very superficial and precisely controlled procedure, meaning that the laser only comes into contact with the surface of your eye. In the unlikely event that an infection or damage was to occur, the chance of your inner eye being affected is extremely low. Our clinic has been operating since 1991 and we are very proud of the fact that we have zero infections on record as a result of laser eye surgery.

You may also find it reassuring to know that Australian surgeons are highly qualified and among the best in the world.

Laser eye surgery is considered safe for eligible patients

During your pre-operative appointment, we take a full medical history, thoroughly examine your eyes, and encourage you to discuss your specific visual goals and any concerns. You will need to allow around 1.5 hours for this appointment and you will have the opportunity to ask as many questions as you like.

If you meet the eligibility criteria, and laser eye surgery is the most suitable treatment, your options include:

A lot of my patients are familiar with LASIK, as this is the most commonly performed procedure. In general, this is because LASIK has a shorter recovery time – not because one procedure is ‘better’ than the other. All produce excellent results and have comparable safety profiles.

However, in some situations, one procedure may be recommended over the others based on factors such as your lifestyle, visual goals, general eye health, and the thickness and symmetry of your corneas.

Choose a reputable clinic with the latest technology

Our clinic is home to a state-of-the-art laser suite, fitted with a SCHWIND AMARIS 1050RS excimer laser and the ALCON LenSx femtosecond laser. The excimer laser has the fastest and most accurate eye tracking available to date. This sophisticated technology translates into excellent visual results and improved safety for our patients.

Laser eye surgery is not ‘one size fits all’

There is no standard solution for correcting refractive errors, so laser eye surgery may not be the most suitable treatment for everyone. For some of my patients, laser eye surgery is recommended in combination with another treatment for a better outcome, or to treat more than one eye condition at the same time. For others, laser eye surgery may not be recommended at all. The decision is tailored to each patient’s individual circumstances, suitability and needs.
