Laser Eye Surgery

Laser refractive surgery is commonly performed to correct refractive errors to eliminate dependence on glasses and contact lens for everyday activities. It is used to correct myopia, hypermetropia, astigmatism and presbyopia. The aim of refractive surgery is to re-shape the curvature of the cornea so that rays of light entering the eye are clearly focused onto the retina. There are two types of laser procedures that can be performed, PRK and LASIK.


PRK is a surface procedure to the eye, which allows refractive adjustments of the cornea. This is the most common procedure to correct refractive errors. PRK has been available since 1992 and refinements in laser technology have produced better results. During PRK the surface layer of cells (epithelium) is gently removed by a laser and the underlying cornea is sculptured using the Schwind Amaris 750S Excimer laser in accordance with the patient’s individual refractive error. The recovery after PRK is slow and there are moments when the eye can be uncomfortable and this is usually dealt with by using a bandage contact lens in the first three-four days postoperative. Local anaesthesia in the form of eye drops is used during the procedure, as well as a mild oral sedative if the patient wishes. Generally patients need a week off work after the procedure.

SMILE is a new technique providing treatment of some cases of myopia, where lenticular tissue is removed using a femtosecond cutting device. Tissue is not lost but rather removed via a pocket and this allows the eye to recover without loss of structural weakening as may be the cause with LASIK. The remaining tissue of the cornea after SMILE procedure is still intact.

Trans-epithelial ‘no-touch’ laser

Trans-epithelial PRK is the newest advancement in performing PRK procedures and it is unique to the Schwind Amaris 750S Excimer laser. The laser in ‘one-step’ removes the epithelium (surface layer) and does the laser concurrently. The advantages of this technique are the precise removal of epithelium allowing for faster healing, reduction in pain during recovery and the manual aspects of the PRK are minimised, making it a ‘no-touch’ procedure.

LASIK (Laser Assisted In-Situ Keratomileusis)

LASIK has become the most popular form of laser vision treatment. LASIK is a refractive procedure allowing a change in power of the eye under the protection of a flap. At Central Sydney Eye Surgeons, a femtosecond laser (link to Z-Lasik info) rather than a blade is used to create a flap. Once the flap is created, the flap is lifted exposing the deeper tissue of the cornea allowing further laser treatment with an excimer laser to alter the shape of the eye. This in turn will allow a change in refractive power. The advantages of LASIK include a relatively painless recovery and almost instant refractive alterations presenting a ‘wow’ effect. Not all people are suitable for LASIK and detailed investigative tests would be required to determine one’s suitability. Local anaesthesia in the form of eye drops is used during the procedure, as well as a mild oral sedative if the patient so wishes. Use of the Z-LASIK femtosecond laser allows remarkably quick visual recovery. Most patients will begin to see clearly 2 hours after the procedure with good vision being achieved the following day.

Wavefront Customised Treatments

At Central Sydney Eye Surgeons we use the most advanced technology, allowing customised treatments for each individual eye. Central Sydney Eye Surgeons we use wavefront technology to personalise your treatment plan to achieve the most precise results possible.

Initial Assessment

At your initial consultation you will meet the Central Sydney Eye Surgeons team. You will have an extensive eye examination to ensure your eyes are healthy and to determine if you are suitable for laser eye surgery. Your eyes will be assessed initially by an Orthoptist (clinical staff) prior to meeting your surgeon. At this consultation we will discuss all the surgical options to determine which type of surgery best fits your eyes and lifestyle.

The assessment will take approximately 1 – 2 hours. Dilating drops will be used to open your pupils. This will make your vision blurry for 2 – 3 hours. You will have difficulty to read at near and you will be sensitive to sunlight until the drops wear off. It is advised you bring a pair of sunglasses with you and organise other forms of transport for the way home as you will not be able to drive after this appointment, until the drops wear off.

If you wear contact lenses, it is best you leave them out for a period prior to your assessment, as contact lenses can alter the shape of the eye. For soft contact lens wearers we ask that you leave your contact lenses out for 2 days prior to the assessment and for hard contact lens wearers leave them out for 1 week prior to the assessment. If contact lenses are not left out, the assessment can still be performed however contact lenses must be left out for a longer period prior to the surgery day, where repeat measurements will be taken.

Your eye assessment will involve:

  • Detailed History
  • Vision assessment: your prescription will be assessed
  • Corneal topography: will be used to map the shape of your cornea (front surface of the eye) and to determine the corneal thickness. Your surgeon will use these maps to plan your surgery to achieve the most precise results possible.
  • Wavefront Analysis: looking for discrepancies in your visual system that may impact low light vision
  • A full dilated eye examination
  • Discussion of options that best suit your eyes and lifestyle
  • Opportunity for you to ask any questions you may have
