The Technology

Home / Equipment

At Laser Vision Clinic Central Coast we utilise the MEL 80 laser’s advanced eye tracking, flying Gaussian spot laser beam and optional wavefront guided laser eye treatment to produce the best patient outcomes yet.  It is the powerful combination of Zeiss’ MEL 80 and VisuMax, together with the sophisticated diagnostic capability of the CRS Master, which allows us to provide patients with what we believe is currently the best laser vision correction surgery equipment available in the world.

Manufactured by Carl Zeiss Meditec, VisuMax femtosecond laser and MEL 80 Excimer laser constitute the most sophisticated and technologically advanced laser refractive system available anywhere in the world.  Unlike competing laser systems, Carl Zeiss designed both systems from ground up to work together seamlessly and to provide highly sophisticated, predictable and safe laser vision correction surgery.


VisuMax femtosecond Laser

VisuMax is the fastest femtosecond laser currently available. This leads to enhanced clinical outcomes for patients as compared to other lasers on the market.
A femtosecond laser produces extremely short pulses of infra-red light which are used to divide the corneal tissue. A femtosecond is 0.000,000,000,000,001 second (one quadrillionth of a second). One femtosecond compared to one second is like the diameter of a human hair compared to the distance between the earth and the moon.

The VisuMax laser produces 500,000 pulses a second, each pulse lasting only a few femtoseconds. Each laser pulse produces a microscopic gas bubble which separates the surrounding corneal tissue. Thousands of closely computer guided laser pulses join together to create a highly precise incision in the corneal tissue.

The accuracy of the VisuMax femtosecond laser allows a flap to be cut and lifted out of the way so that the tissue under the flap can be reshaped to correct refractive error.


MEL 80 Excimer Laser

The excimer laser uses high-energy pulses of ultraviolet light to alter the shape of the cornea. It does this by removing extremely tiny amounts of tissue (25 100,000ths of a millimetre at a time), without disturbing other tissue.

MEL 80 laser enables extremely safe and precise correction. Highly developed optics focus the laser beam in a very small spot size and an optimal Gaussian shape. This makes the finest corrections possible and the surrounding tissue unharmed. Intelligent technology tracks the slightest eye movements during laser eye treatment and guides the laser beam to continue to work in precisely the right position.

The surgeon obtains a precise digital “impression” of your eyes, enabling him or her to recognise even the most subtle anomalities in the visual process and plan an individual laser eye treatment optimised for you.
