Why Laser Eye (LASIK) Surgery Works
Having performed over 20,000 LASIK surgery procedures, Dr Binetter is one of the most experienced LASIK surgeons in Australia.
LASIK surgery is the most commonly used technique for vision correction around the world.
With LASIK most patients will see an improvement in their natural eyesight immediately after surgery with a full recovery and correction by 3 months. Indeed, by the next day, the vast majority of all patients have functional vision without glasses and can see well enough to drive a car and return to work.
What happens in the long term following LASIK surgery?
It is possible that results could last a lifetime. Once refraction has stabilised, (usually by 3 months after LASIK surgery), the reshaped cornea is permanently modified – your refractive error corrected.
However, as you age it is important to realise that natural degeneration and other diseases may affect your vision which is a perfectly natural process. Should these arrise we have safe and effective procedures for both cataracts and presbyopia (loss of reading vision).
LASIK Surgery for Myopia or Short-Sightedness
Myopia up to -10 D can now be treated with the Excimer laser. Results will vary according to the severity of the refractive error and the amount of laser treatment that will be required.
Most individuals have myopia less than -3D. Results indicate that up to 99% of this group can achieve 20/20 vision following LASIK surgery. And in those with myopia between -3D to -6D up to 96% can achieve 20/20. Additional treatment can be undertaken when necessary, to gain further improvement in vision. Less than 5% undergo such treatment.
Individuals with extreme levels of myopia greater than -10D can be treated with intraocular lens implants or a combination of refractive surgical procedures including lens implants, and LASIK.
Regression after LASIK surgery is uncommon and usually less than 1% of initial treatments will regress.
Complications associated with LASIK refractive surgery are uncommon. The risk of infection is estimated to be one in 10,000.
Hyperopia or Long-Sightedness
Hyperopia treatment requires a steepening of the curvature of the cornea to increase the magnification power of the eye.
- Results for low and moderate hyperopia are similar to those with myopia with up to 94% achieving 20/20 vision.
Hyperopia greater than +3.0D requires a larger amount of laser treatment. Alternative treatments may be offered such as Intraocular Lens Implants or Refractive Lens Exchange which may provide superior visual results to LASIK surgery. Both reading vision and distance vision is improved by Hyperopic LASIK. However, older individuals may still find a need for reading spectacles. This requirement varies from one individual to another.
Because the Australian Institute of Eye Surgery is so confident of our LASIK surgeons vast clinical experience we stand behind our vision correction results with The Lifetime Commitment for which most patients are eligible. We are the only vision correction centre in Australia to provide this.
