Laser Eye Surgery FAQs

Below are AVC’s laser eye surgery FAQs. Please click on the questions below to reveal the facts and answers:

Lasik treats prescription up to -10D, +5D with an astigmatism of up to -5D. Lasek is able to treat prescriptions up to -9D, +2D with an astigmatism of up to -5D.

Unfortunately not everyone is suitable for treatment, which can be due to the health of the eye or the thickness of the cornea. Suitability is determined at the consultation by the surgeon after comprehensive testing.

Immediate reasons that determine suitability are:

  • Age – Patients’ must be over the age of 18.
  • Prescription –The prescription must be stable.
  • Pregnancy – Being pregnant or having breast fed in the last 2 months.
  • Health – Patients’ with Keratoconus and auto immune diseases.

There is no upper age limit for Laser treatments. Suitability will be determined at the consultation where we will perform comprehensive testing to find out the cause of the visual issues. There are many factors that not only affect suitability for treatment but whether the treatment is best suited to a patients’ needs.

If there is another treatment that could better address the visual problems experienced by a patient then an alternative treatment will be discussed, for example the presence of cataracts.

Wavefront laser eye treatment corrects the aberrations (imperfections) in the eyes which cause a prescription. AVC deliver a gold standard in Laser treatment with our personalised treatment plans and sole use of Wavefront technology. Our state of the art laser eye surgery provides better quality vision and reduces night time glare that can be experienced with inferior Laser treatments.

As with any surgery there are no 100% guarantees. There are many variables, the main being corneal healing. We are able to achieve the same vision as obtained with the use of visual aids and if you have 20/20 vision with glasses or contact lenses, then it is highly possible that this can be achieved after treatment, however this will be discussed at the consultation.

98% of our patients’ achieve 20/20 vision and approximately over 30 to 40% of our patients’ achieve better than 20/20 vision.

Lasik is the most common laser surgery performed worldwide. There has been a lot of research conducted, it has undergone numerous clinical trials and is FDA approved.

As with any surgery procedure Laser eye surgery is not completely risk free. Complications are very rare but these will be explained and discussed at your consultation. Any complications are easily dealt with by our comprehensive aftercare system.

AVC uses the latest Intralase Laser to create the corneal flap, instead of the surgeon creating the flap manually. The Intralase creates a personalised corneal flap with precision and is a safer method, producing improved visual outcomes and faster recovery times.

It will take about 20 minutes to treat both eyes but we recommend our patients’ attend the clinic for 1 to 2 hours allowing enough time to prepare, perform the treatment, recover and be discharged.

AVC’s Advanced Control Eye-tracking (ACE) System is the most sophisticated 3-D eye tracker available and keeps the eye being treated under continuous surveillance.

It uses the unique iris map created at your consultation that is used in your personalised treatment plan that keeps the eye being treated under continuous surveillance. It guides the laser throughout the treatment by tracking and mirroring the movement of the eye, and if there is too much movement it will shut off the laser.

Before the procedure the surgeon will apply anaesthetic drops to numb the eye so no pain is felt. However, the eye lid guard that prevents blinking throughout the procedure can cause some discomfort. Some patients’ also report a sensation of pressure for a few seconds whilst the flap is created.

The protective lens is placed in the eyes as an extra precautionary measure and if it falls out there is no need to replace it. The lens is removed at the first post-operative check which for Lasik is one or two days after treatment and for Lasek is 4 to 5 days. We recommend not to touch the lenses, even if you are an experienced lens wearer.

At first your vision will be a little blurry after surgery and this wears off a few hours after treatment. Recovery times after laser eye surgery vary as everyone’s eyes heal independently at different rates. Initial recovery after Lasik treatment is usually 24 to 48 hours and for Lasek is 3 to 4 days. It is recommended that all aftercare instructions are followed to aid recovery.

The majority of our patients’ are back to work within 24 to 48 hours. However, this can vary due depending on your occupation; working in a dusty environment may mean that more time off is needed. The amount of time off work needed will be suggested by the surgeon at your consultation.

At your first post-operative check, your surgeon will examine your eye to determine how your vision is recovering and advise when to start driving. It is typically between 1 to 2 days after treatment for Lasik and 3 to 4 days after Lasek.

No patient at AVC have ever gone blind. The chances of going blind are extremely rare and with AVC’s comprehensive aftercare it would be impossible.

The treatment will last a lifetime.

However, it will not prevent natural deterioration that can be caused by health issues and environmental factors. If there is a deterioration in vision, retreatment may be required to correct the remaining prescription. Laser treatment will not prevent the natural aging of the eye that leads to presbyopia which is a reading prescription.

This is where one eye is corrected for short sight and the other is corrected for long sight. To be able to have this form of treatment patients’ must undergo a contact lens trial to ensure they can adjust to this type of vision. Half of the individuals that try this cannot get used to Monovision and can suffer from imbalance and headaches.
