Am I Suitable?

Am I suitable? More than ever, the answer is probably “YES”!

It is necessary to have a thorough examination to see if Laser Vision Correction will work for you, but there are a few general guidelines that may indicate suitability.

If you can answer yes to the following questions you may be a candidate for the Lasik or SMILE Procedure : 

  •   Are you at least 18 years of age?
  •   Not pregnant or breast feeding?
  •   Do you have generally healthy eyes?
  •   Do you see well when wearing glasses or contacts?

You may be suitable.

Find out if you are suitable for Laser Vision Correction

Which Procedure?

Our advanced technology has put Laser Vision within reach of many patients who were simply not suitable in the past. Our SMILE minimally invasive procedure offers incredibly accurate computer-guided precision that is making laser vision a reality for thousands more patients around the world. Plus, if you are not suitable for SMILE/Lasik/surface laser, our advanced range of lens implants can provide equally outstanding results.

You can now consider vision correction if you suffer from:

  •   Astigmatism
  •   Near or short-sightedness (SMILE only suitable in cases of short-sightedness)
  •   Long sightedness or hyperopia
  •   Thin, flat or steep corneas
  •   Need reading glasses
  •   Or if you are simply frustrated with other prescription glasses and contact lenses

Note: Laser Vision Correction (LVC) cannot improve vision impaired due to reasons other than the need for glasses or contacts. For example, LVC cannot restore vision lost to diabetes, cataract, glaucoma, age related macular degeneration or poor vision in one eye from childhood.

No matter what your prescription, our state-of-the-art technologies and vision correction procedures means we are likely to be able to assist you in reducing your dependence on spectacles or contacts.

  • Normal Vision (emmetropia):
    Normal Vision (emmetropia):

    Light rays are refracted by the cornea and the lens in such a way that the focal point is directly on the retina.  Objects both near and far appear in sharp focus.

  • Nearsightedness (myopia):
    Nearsightedness (myopia):

    Light rays are refracted by the cornea and the lens in such a way that the focal point is in front of the retina.  Distant objects appear out of focus.  Depending on the degree of myopia, near objects appear in sharp focus.

  • Farsightedness (hyperopia):
    Farsightedness (hyperopia):

    Light rays are refracted by the cornea and the lens in such a way taht the focal point is behind the retina.  Depending on the extent of the farsightedness, objects which are close, and even distant ones in some cases, appear out of focus.

  • Astigmatism
    Astigmatism

    The irregular curvature of the cornea causes the light rays to be refracted into mulitple focal points and not just one.  Depending on the extent of the astigmatism, objects both near and far appear skewed and distorted.

Keratoconus

The most common reason people are not suitable for laser vision correction is an eye condition called Keratoconus. This changes the shape of the cornea, the front lens of the eye. Keratoconus occurs in about one in 2,000 Australians. In addition there is often a family history of Keratoconus, corneal transplants, or hard contact lenses. So if you have no family members who have needed corneal transplants or hard contact lenses, you can assume you are suitable for laser vision correction. Consult your optometrist for testing or to find out more about Keratoconus.

Alternatives To Laser

While a lot more people are suitable for laser vision correction than they think, particularly with new technologies, there are some people for whom different vision correction procedures are a better options. These include:

  • Surface laser
    Surface laser

    This is where the cornea on the front of the eye is still refocused using the VISX excimer laser, but the surface layer is removed rather than being lifted as a flap. This technique is used where the cornea is too thin and /or the prescription correction too high to leave sufficient remaining cornea after correction if the usual Lasik flap is created. The eye is a little more uncomfortable afterward, and vision takes a little longer to return and stabilise, but surface laser is still a good method of laser vision correction. Special anaesthetic drops and contact lenses needed for the first few days only, can make the eye much more comfortable. Special cold solutions and “antimetabolites’ used in the procedure help keep the cornea clear, compared with early days of surface laser two decades ago.

  • Phakic IOLs
    Phakic IOLs

    These are essentially like placing a contact lens permanently inside the eye so you don’t have to put them in and out eye daily, weekly, or monthly, along with all the cleaning, storage and lens care that goes with contacts. But the phakic IOL can always be removed later if required, which is one of the best things about them. Phakic IOLs are the only completely reversible vision correction procedure. We use the Staar Visian ICL version VC where possible. This lens is a significant improvement on earlier phakic IOLs. It is placed behind the pupil where you cant see it, in a 20 minute procedure performed under anaesthetic drops and sedation in our day procedure centre. The risk of the procedure is low, and the recovery of vision very fast and quality of vision obtained excellent. This lens is often used for those patients who require a vision correction greater than even modern lasers can be safely used for, ie patients who are very long or very short sighted, or for whom laser vision correction is not suitable because of thin corneas, dry eye, or other reasons.

  • Clear lens extraction
    Clear lens extraction

    Clear lens extraction is essentially the same as cataract surgery, except the crystalline lens removed is clear, not yet having become a cloudy cataract. The intraocular lens (IOL) is then put in the place of the clear crystalline lens which has been removed. Clear lens extraction involves about a 2 ½ hour visit to our dedicated day procedure centre in Eastwood. No injections are used around the eye, so there is no patch needed or bruising after the procedure. Patients see well after 36 hours and carry on with almost all normal duties after 24 hours.

  • Monovision (for Presbyopia/Reading glasses)
    Monovision (for Presbyopia/Reading glasses)

    This is a method to decrease dependence on reading glasses. In monovision, the patient’s dominant eye is set for distance and their non-dominant eye is set for intermediate or near vision. We can help you determine which eye is dominant. Monovision could be thought of as the modern version of the old fashioned monacle. Though it sounds a little strange, in fact most people who select monovision do extremely well with it, adapting over just a few weeks to their new vision. In fact, monovision is the commonest way people avoid using reading glasses when over 45 years of age. A modified form of monovision can be achieved with insertion of a multifocal IOL into the non-dominant eye after clear lens extraction for that eye.

  • ICL
    ICL

    "ICLs can be thought of as Internal Contact Lenses". They are used for patients generally < 45 years old, who do not need reading glasses yet when corrected for distance vision, and who may not be suitable for laser vision correction. The ICL sits in the eye behind the coloured part of the eye, the iris, and therefore cannot be seen. They are placed inside the eye, so cannot be felt like external contact lenses. They stay in the eye and do not need any maintenance, do not degrade or reject. If in later life you need cataract surgery, they do not interfere with cataract surgery and can be removed at the same time. They are inserted in a short procedure at our dedicated day procedure centre, without any needle injections around the eye, meaning there is no eye patch and no bruising after. You can continue with almost all activities 24 hours after the procedure. If both eyes require ICLs, insertion for each eye is usually performed separately , one week apart.
