Technology

PERTH Laser Vision has performed laser eye surgery procedures on more than 18,000 eyes, achieving a sound record of excellent results and patient satisfaction.

The centre continues to offer the latest technology in Perth with the addition of the IntraLase Femtosecond (FS) laser.

The IntraLase FS represents the latest improvement in LASIK surgery. LASIK is a two step procedure which requires the surgeon to first create a micro-thin corneal flap, which is then lifted allowing the Excimer laser to be applied to reshape the eye to correct either short-sightedness, long-sightedness or astigmatism. This flap was previously created using a small blade and an instrument called a Microkeratome. Now the flap can be created using the IntraLase FS laser. As the IntraLase FS moves across the eye it creates a layer of bubbles at a specific depth in the corneal layer. The flap is then lifted by separating the tissue where the bubbles have formed.

This technology represents an emerging standard of care in LASIK worldwide. With its excellent safety profile and superior visual outcomes, the IntraLase Method is among the fastest-growing refractive surgical techniques and more than 1,000,000 LASIK procedures have been performed using the IntraLase Method.

The Excimer laser is used during the second step of the procedure to correct the refractive error. Zyoptix is a system developed to provide a personalised vision solution for each individual laser treatment. The effect is even greater precision in the treatment of refractive errors. Zyoptix uses wavefront analysis, a method that measures the total refractive error and corneal shape of each eye. Through combining the diagnostic capabilities of the Orbscan IIZ with the Zywave Aberrometer, a unique prescription is calculated and then loaded into the Bausch & Lomb Excimer laser using a specialised software system. This technology when combined with the lasers' 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 Excimer equipment.

Orbscan IIZ

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

Zywave Aberrometer

This instrument uses wavefront technology - directing a beam of light into the eye, the beam reflects off the back of the eye and the Zywave measures the shape of the wave of light that is reflected out of the eye from, a specific point, thus revealing any abnormalities within the entire optical system.
