Laser Eye Surgery Technology

Advanced Vision Care is the only clinic that uses the very latest, cutting edge laser eye surgery technology in all of our treatments:

NEW Technolas TENEO 317 Laser by Bausch and Lomb

NEW Technolas TENEO 317 Laser by Bausch and Lomb

At Advanced Vision Care we only use the most advanced laser eye surgery technology and the Bausch & Lomb Technolas TENEO 317 (released in 2017) is the fastest treating and newest excimer laser available, and provides some of the best outcomes. It provides optical sculpting by precisely evaporating tissue from the collagen layer of the cornea.

  • Fast: 1 sec per dioptre – typical treatment lasts only 3 seconds, which allows for a reduction in thermal effects on the cornea leading to quicker recovery time
  • 500Hz ‘flying spot’ laser – able to create complex and customised treatments for short-sightedness, long-sightedness, astigmatism and presbyopia
  • Bausch + Lomb Technolas have over 20 years of refractive experience in making vision-correcting lasers with unparalleled precision, stability and accuracy

Eyetracker

eyetracker

  • Tracks all eye movements – 6 dimensions (XYZ, intraoperative rotations and static rotations using Iris Recognition)
  • Takes pictures of the eye (sampling rate) 1,750 times per second (1750Hz)
  • Has a response time of 2ms – so no laser pulses are ever misplaced
  • The Eyetracker can follow the most sudden or subtle of eye movements

Iris Recognition

  • Iris picture captured on our sophisticated aberrometer (Zywave)
  • Thousand times more accurate than a fingerprint
  • Ensures accurate placement of your personalised laser treatment
  • Especially important for patients with astigmatism, night vision problems or irregular corneas

Advanced Wavefront

The Bausch & Lomb Zywave Aberrometer meticulously measures the prescription and imperfections (aberrations) of the eye. It does this by passing a beam along 9000 points of the cornea to the retina and calculates the required refractive errors in these exact locations. This data creates a refractive and aberrations profile of each pupil.

The Zywave Aberrometer then uses the Zernike algorithm to mathematically reconstruct the wavefront. As the Zywave Aberrometer measures total wavefront aberrations and mathematically represents them up to the 5th order Zernike terms, it not just limited to sphere and cylinder (used for glasses and contact lens prescriptions). This data, combined with the many tests performed at your consultation, is used to create a truly personalised treatment plan.

Intralase Laser

Intralase has revolutionised Laser surgery by making the creation of the flap even safer and, consequently, has improved the precision, recovery time and the quality of vision achieved.

intralase laserIntralase is a femtosecond laser that uses tiny, rapid pulses of harmless light to create a corneal flap, instead of using a blade. Each pulse of light passes through the top layers of the cornea and forms a microscopic bubble at a specific depth and position within the eye that is determined by the personalised treatment plan.

The Intralase laser moves back and forth across the eye, creating a uniform layer of bubbles of carbon dioxide and water vapour. These bubbles are precisely positioned to define the flap’s dimensions and hinge location. These bubbles expand to push the cells apart allowing the flap to be gently lifted and rested.

Intralase is able to create extremely precise corneal flaps that are stronger and thinner which consequently boosts the recovery time.

The corneal flap creation only takes 15 to 20 seconds. Once complete the flap can then be gently lifted and easily separated where these bubbles have formed to expose the area of the cornea that will be treated.
