Laser Eye Surgery With Wavelight Femtosecond (FS200) Laser

Perth Laser Vision continues to offer the latest eye laser surgery technology in Perth with the addition of the Wavelight Femtosecond (FS200) laser. The Wavelight FS200 represents the latest development in LASIK eye laser surgery and is exclusive to Perth Laser Vision.

LASIK is a two-step procedure which requires the surgeon to first create a micro-thin corneal flap on the surface of the eye, which is then lifted allowing the Excimer laser to reshape the eye to correct the refractive error. This flap is created using the Wavelight FS200 laser. As the Wavelight FS200 laser is directed across the eye by computer ontrol, it creates a microscopic layer of bubbles at a specific depth just beneath the corneal surface. The flap is then lifted by separating the tissue where the bubbles have formed. This technology represents the accepted standard of care in LASIK worldwide. With its excellent safety profile and superior visual outcomes, the Femtosecond Method is the safest refractive surgical technique with more than 8 million LASIK procedures performed using the Femtosecond Method.

Laser Eye Surgery With The Wavelight (EX500) Excimer laser

The Wavelight EX500 Excimer laser is used during the second step of the eye laser surgery procedure to correct the refractive error. Featuring a 500 Hz repetition rate, the WaveLight® EX500 Excimer Laser delivers the world’s fastest treatment times, resulting in consistent outcomes. Its innovative engineering helps reduce the potential for:
•  Sensitivity to eye movements
•  Patient eye fixation fatigue
•  Dehydration of the cornea with delayed or prolonged treatment times
•  Reduces the potential for night-time glare and halos

With a multi-dimensional eye tracker keeping a check on the eye position over 1000 times each second, the WaveLight® EX500 Excimer Laser offers exceptional precision and safety:
•  Movement tracking at 1050Hz and 2 msec latency
•  Dynamic pupil tracking actively adjusts the laser position for eye movements

Topographic mapping for eye laser surgery

Topography guided treatment is a method that measures both the total refractive error and corneal shape of each eye. It provides a personalised vision solution for each individual laser treatment. The method enhances precision in the treatment of refractive errors. Through combining the diagnostic capabilities of the Oculyzer with the Topoyzer, a unique prescription is calculated and then loaded into the Wavelight EX500 Excimer laser using a specialised software system. This technology, when combined with the laser’s infra-red eye tracker to monitor and follow eye movements, and the flying spot laser beam principle, produces even greater precision, accuracy and efficiency further boosting the excellent results already achieved by standard Excimer equipment.

Oculyzer Diagnosis for Laser Eye Surgery

This diagnostic device produces a comprehensive topographic map of both the external and internal surfaces of the cornea, to measure its thickness, elevation and curvature.

Wavefront Aberrometry

This instrument measures the refractive wavefront – a small beam of light is directed into the eye, reflects from the retina at the back of the eye, it can measure from multiple specific points externally, the tiniest deviation of the light ray as it exits the eye through the pupil, thus revealing any abnormalities within the entire optical system.

LenSx® Femtosecond Laser Assisted Cataract Surgery

As one of the first providers of eye laser surgery in Western Australia, Perth Laser Vision has always been at the forefront of the latest eye surgery technologies. Now, the LenSx® laser is the first of its kind in Western Australia, offering the incomparable benefits of laser cataract surgery to our patients.

This femtosecond laser is proven technology for laser cataract surgery and lens replacement procedures.

Staying abreast of technological advances in refractive lens surgery has and always will be essential to the success of Perth Laser Vision. Our latest technology continues this tradition by tailoring cataract and lens replacement surgery to the individual patient to ensure the best possible outcome. We now perform LenSx® laser lens surgery to enhance the vision of our patients by using the latest advances in technology. Perth Laser Vision is the first eye centre in Perth to be using this incredible tool, so contact us today at our Subiaco or Murdoch laser eye clinics to learn more about the bladeless alternative to traditional cataract and lens replacement surgery.

A customised solution
Every eye differs in its size, depth, thickness and curvature of its cornea, so precise measurements and mapping are critical during the planning stages of the eye laser surgery. The LenSx® platform uses a suite of sophisticated technologies such as integrated optical coherence tomography (OCT) to gather these measurements by creating detailed digital images of your eyes. These images allow us to plan and perform lens surgery with unprecedented precision and a level of customisation not possible with manual methods.

Increased accuracy and precision
The LenSx® computer-controlled laser places corneal incisions more accurately than is possible with a handheld blade.  It enables lens implantation to be more predictable than before and enhances the visual results.

Enhanced patient comfort and safety
The LenSx® laser platform enhances the patient’s experience in terms of both comfort and safety by reducing the surgical time.

It can be used with premium lens implants
After the LenSx® laser has helped create all the required incisions, a premium intraocular lens (IOL) such as PanOptix multifocal lens Implant can be placed into position. The placement of a premium IOL typically decreases a patient’s dependence on glasses or contact lenses for distance and reading. Due to the LenSx® laser’s ability to decrease or eliminate astigmatism also, the results of these fantastic new lenses are even better.

Eye laser surgery provides improved chances to see better fast
As more eye surgeons begin offering LenSx® laser lens surgery, thousands of patients will have the opportunity to attain better, uncorrected vision without the interference of age-related loss of focus or cataracts.
