LASIK is a two step procedureSTEP ONE: First a flap is created in the cornea (front clear window of the eye). At Fendalton Eye Clinic Dr Kent uses the IntraLase Laser to create a precision LASIK flap.
Some clinics still use a bladed instrument (microkeratome) to cut the corneal flap, a less precise means of making the corneal flap. While LASIK is extremely safe if complications occur the microkeratome (blade) is most often the cause.
At Fendalton Eye Clinic, using the precision of the IntraLase Laser to "create" rather than "cut" the corneal flap provides added safety for our patients with a more predictable outcome.
With the IntraLase 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 of High Definition LASIK® involves programming the excimer laser to reshape the inner layers of the cornea with your personalized treatment profile, incorporating iris recognition technology to achieve the desired vision correction.
How does the IntraLase laser make the LASIK flap?The IntraLase laser allows us to tailor-make a precise corneal flap based on what is best for your eyes.
- We programme the IntraLase 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 IntraLase 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 your doctor and is individualized to the way your eye is shaped. The Intralase laser flap is created in around 20 seconds.
- The flap is then lifted and the excimer laser reshapes the inner layers of the cornea. The surgeon then repositions the IntraLase flap back into place where it “locks” into position.
Benefits of creating the LASIK flap with an IntraLase laser
- The safety and accuracy of 100% bladefree, all laser LASIK procedure – a blade never touches your eye.
- The chance of a perfect flap with the IntraLase is nearly 100%. In comparision between 1 in 100 and 1 and 500 procedures with microkeratome LASIK have a problem with creation of the flap.
- Enables more people to achieve 20/20 (normal) vision or better compared to using a microkeratome. 1
- Creation of the LASIK flap with IntraLase is preferred by patients. Vision is preferred 3 to 1 over eyes treated with blade initiated LASIK eye (among those who stated a preference). 2
- Proven technology that has been available in the USA since 2001.
- To date over one million people have had their LASIK flap created using IntraLase.
- Virtually all the leading excimer laser centres worldwide now offer IntraLase LASIK.
- IntraLase LASIK is the only LASIK surgery approved for use in USA AirForce pilots. Studies with microkeratome LASIK showed too much loss of quality of vision. In comparison, IntraLase LASIK has been shown to maintain quality of vision.
