With LASIK at Fendalton Eye Clinic in Christchurch, Dr David Kent uses the safety, precision & accuracy of a Zeiss VisuMax® femtosecond laser to create a flap in the cornea. With a laser creating the flap, Dr Kent achieves the exact thickness of flap that is required.

We are committed to the safety and precision of your laser eye surgery treatment. NASA will only allow their fighter pilots and astronauts to have a LASIK procedure that is carried out with a femtosecond laser creating the corneal flap, you deserve this level of safety and accuracy too.

There are two steps to the LASIK procedure.

Step One:


First a flap is created in the cornea (front clear window of the eye). At Fendalton Eye Clinic, Christchurch, Dr David Kent uses the Zeiss VisuMax® (a femtosecond laser) to create a precise LASIK flap.

Dr Kent, using the precision of a laser to "create" rather than "cut" the corneal flap provides added safety for patients with a more predictable outcome.

With a femtosecond laser we can create the corneal flap using the safety and accuracy of a computer guided laser - without a blade ever touching your eye.

 Step Two:


The precise flap created by the Zeiss VisuMax® laser is lifted. For the second step of the LASIK procedure the Schwind Amaris  excimer laser is used to reshape the inner layers of the cornea with your personalised treatment profile, incorporating eye recognition technology and the exceptional accuracy that only the Schwind Amaris excimer laser can deliver with its unparalleled precision, following every minor movement of your eye employing the unique seven dimensional eye tracker, ensuring accurate delivery of each laser pulse of treatment, adjusting the laser beam for every microscopic movement of your eye in all directions.


How does the Zeiss VisuMax® (femtosecond) laser make the LASIK flap?

The Zeiss VisuMax® laser allows Dr Kent to tailor-make a precise corneal flap based on what is best for your eyes.

Dr Kent programmes the Zeiss VisuMax® laser to deliver tiny rapid pulses of laser, forming microscopic bubbles focused at a precise depth inside the cornea. This process is know as photodisruption.


The Zeiss VisuMax® femtosecond laser creates rows of these bubbles just beneath the corneal surface as it moves back and forth across your eye in a uniform plane - creating a cleavage plane.

  • The edge of the flap is created by stacking laser pulses at an angle that is determined by Dr Kent and is individualised to the way your eye is shaped. The Zeiss VisuMax® laser flap is created in around 20 seconds.
  • The flap is then lifted and the excimer laser reshapes the inner layers of the cornea. Dr Kent then repositions the flap back into place where it naturally “locks” into position due to the action of the endothelial cells on the cornea.
