Laser eye surgery Brisbane
Laser Eye Surgery
A core service provided by Brisbane based Eye Surgeon Dr. Cameron McLintock is laser eye surgery, which is a highly effective treatment for refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism.
Laser eye surgery is performed while patients are awake and reclining, which means that this particular surgery is minimally invasive.
If you would like a permanent solution to improve your vision without the need for glasses and contact lenses then consider laser eye surgery performed by Dr. Cameron McLintock.
What Is Laser Eye Surgery?
Laser eye surgery is a very common form of surgery designed for the purpose of improving vision and correct refractive errors, such as myopia (“short-sightedness”), hyperopia (“long-sightedness”) and astigmatism.
A refractive error occurs when the eye does not focus light correctly. To achieve clear vision without glasses or contact lenses, the eye needs to focus the light travelling through it. In those with myopia (“short-sightedness”), hyperopia (“long sightedness”) and astigmatism, light is poorly focused by the eye resulting in blurred vision. Presbyopia is a condition in which the eye, with age, loses its ability to focus on near objects. Presbyopia occurs in the mid 40’s and affects everyone. Initially it is apparent as the need to hold near objects further away from the eye to obtain a clear image.
The types of problems that laser eye surgery can correct include:
- myopia (“short-sightedness”)
- hyperopia (“long-sightedness”)
- corneal scarring
- recurrent corneal erosion syndrome
Types of Laser eye Surgery:
There are several types of laser eye surgery that can be performed by Brisbane Ophthalmologist Dr Cameron McLintock to treat the above conditions. These include:
- Surface LASIK (also known as photorefractive keratectomy, PRK)
- PTK (Phototherapeutic keratectomy)
LASIK is a type of laser eye surgery used to treat refractive errors such as myopia (short- sightedness), hyperopia (long-sightedness) and astigmatism. LASIK acts in a similar way to glasses or contact lenses but is a permanent treatment. In LASIK a flap is created in the cornea (clear window at the front of the eye), the flap is lifted, and the laser is applied to the deeper layers of the cornea. The laser changes the shape of the cornea and alters the way it focuses light, resulting in much clearer vision.
Surface LASIK, like LASIK is a type of laser eye surgery that uses laser to change the shape of the cornea. In surface LASIK the laser is applied to the surface of the cornea, not the deeper layers. Both LASIK and surface LASIK have been shown to produce excellent long term outcomes in vision.
Phototherapeutic keratectomy (PTK)
PTK is a type of laser eye surgery which is used primarily for removing opacities of the cornea such as scars. It can also be used to make the surface of the cornea more regular, for example in eyes with Keratoconus.
What to expect during laser eye surgery
No pain is felt during laser eye surgery. Drops are placed in your eyes to numb them and you can also request a very mild sedative to calm your nerves before treatment begins. The laser eye surgery treatment then starts and only lasts a minute or two. During the surgery, your eye is held open so that you don’t blink during the operation. treatment is done.
Am I Eligible for Laser Eye Surgery?
Before you obtain laser eye surgery, it's important to understand that not everyone is eligible for this surgery. Prior to having any laser eye surgery performed, Dr Cameron McLintock will ensure that the surgery is safe for your eyes.

Non-Laser Surgery Options
REFRACTIVE LENS EXCHANGE
In a refractive lens exchange, the natural lens of the eye is removed and replaced with an artificial lens that is permanently implanted into the eye to correct any focusing error. Refractive lens exchange is most commonly performed for presbyopia. There are 3 ways in which the need for glasses or contact lenses can be reduced in refractive lens exchange.
Option 1: Multifocal artificial lens implant in both eyes.
Multifocal intraocular lenses provide excellent vision for objects at all distances. They provide excellent distance vision (driving, watching TV), intermediate vision (eg working with computers) and near vision (eg reading tablets, phones, books). They are the lens type which are most likely to result in spectacle independence. In some people multifocal lenses can result in haloes around lights which are most commonly noticed when driving at night. Usually these are very mild. However, in around 1 in 200 cases, haloes can be very troubling to the point where these lenses need to be removed.
Option 2: Extended depth of focus (EDOF) lens implants.
EDOF lenses provide not only excellent distance vision without glasses (eg driving, watching TV), they also provide excellent intermediate distance vision (eg working with computers).
EDOF lenses also provide some degree of near vision (eg reading tablets, phones, books), although glasses are still required to read small print, particularly under low light conditions. Although the near vision provided by EDOF lenses is not quite as good as that provided by multifocal lenses, it is very rare for haloes to be noticed by patients.
Option 3: “Blended vision” or “monovision.”
In blended vision, artificial lens implants are inserted which result in one eye being focused for distance and the other eye being focused for near.
Blended vision significantly reduces the need to wear glasses after cataract surgery. It usually allows people to be glasses-free for most daily activities.
Patients may still require glasses for reading very fine print and/or for driving at night. Because one eye is focused for distance and the other for near, it can take the brain a few months to fully adapt to blended vision.
IMPLANTABLE COLLIMER LENS (ICL)
The ICL is an artificial lens implant that is inserted into the eye and placed in front of the natural lens, inside the eye. It is akin to a permanent contact lens. Each ICL is custom made for the individual eye.
ICLs have traditionally been used in eyes with varying degrees of refractive error where PRK and LASIK may be less likely to have an excellent outcome. With recent advances in the designs of these lenses and increased safety, the ICL is being increasingly used in eyes with lower refractive errors as an alternative to PRK and LASIK.
Benefits of ICL
There are many benefits of the ICL. These include the fact the procedure is reversible (in the very unlikely event of an unsatisfactory outcome, the ICL is simple to remove), whereas PRK and LASIK are not.
Also, an ICL doesn’t change the shape of the cornea like PRK and LASIK do. In the future, most people will require cataract surgery, where the natural lens that has become clouded (ie a cataract) is removed.
In eyes that have had prior PRK or LASIK, determining the correct strength of lens to implant into the eye at the time of cataract surgery can be very challenging. There is increased risk of the focus not being correct in the eye.
In an eye with a prior ICL, this is not an issue and cataract surgery can be performed with confidence that the lens implant that will be inserted into the eye will be correct.
Other benefits include the fact that there are none of the possible complications that can occur in LASIK due to the presence of a corneal flap, such as dislocation from trauma, dry eye and changing corneal shape with time (post-LASIK ectasia).
