This is a registered trademarked procedure registered by AMO in November 2007. Many components used like the Visx Excimer laser and Intralase were used either individually or in combination by many surgeons over last 4 years. It is only recently all components of the iLASIK have the latest of the star S4 laser and IntraLase 60 can be truly called iLASIK. Eyetech was the first in Canada to buy the latest Visx Star S4 IR laser when ILasik was introduced for the first time in early part of this year.

The components of iLASIK are:
Step 1 – Creating Your Personal Vision Profile for your best personal vision
Step 2 – Bladeless creation of corneal flap using INTRALASE®C FS Laser
Step 3 – Advanced CustomVue laser correction using Visx Star S4 IR Excimer Laser
Step 1 – CustomVue™ WaveScan Wavefront®
The first step in the iLASIK procedure is to perform a series of tests to determine the individual characteristics of your vision, including the use of our WaveScan™ technology. Your correction in your glasses is not unique. Glasses and contacts are limited in their ability to correct unique imperfections in each individual’s vision. In fact, millions of individuals have the same eye glass prescription. With the CustomVue procedure, no two “prescriptions” are identical. The WaveScan system creates a 3-D map of the unique imperfections of your eyes. Then our Advanced CustomVue™ process uses the digital information from that map to design a custom treatment for each of your eyes. The wavefront analysis for each eye is very unique for you and only you.
Other systems use similar equipment to customise your vision. The big difference is the other laser analyses 78 points on the whole cornea and our system measures 240 points in a 6.5 mm pupil area. We get more data to do more refined custom correction. Most other systems analyse up to 4th or 5th order of wavefront abnormalities. Visx CustomVue WaveScan measures up to and beyond 8th order abnormalities. Our system is the only one calculating the data by Fourier mathematical analysis to give you the best possible personalised vision correction.
Fourier-based wavefront algorithms:
- Fourier delivers the highest resolution available of the wavefront error
- Uses more data points to derive the optimal shape
- Uses all data from any shape of pupil
- Accurately reconstructs all peripheral data
- Captures and treats higher and lower order aberrations up to 7 mm diameter pupil
Imagine the personalisation you can get with our system! It is all here for you.

Step 2 – making the iLASIK Flap
The iLASIK procedure exclusively uses an advanced technology called the IntraLase™ Method. The IntraLase Method is a 100% blade-free approach to creating your corneal flap. After your eye is numbed with anaesthetic drop a circular ring is placed centering your cornea. A gentle suction is applied to steady the ring. The IntraLase laser is "docked" on to the ring. Laser is delivered through the docked system. The flap is created by the laser creating one micron cleavage at a time in rapid succession. The flap is completed by the laser cutting the out -line of the flap. The hinge of the flap is usually placed at the top so the movement of the upper eyelid does not displace the flap. After the flap is created in one eye the other is engaged in a similar procedure to create the corneal flap before proceeding with the laser correction.

Step 3 – Your Laser Vision Correction
Now that you’ve had your personal vision profile using WaveScan technology and your blade-free corneal flap using the exclusive IntraLase Method, your vision can be corrected using the Advanced CustomVue treatment with Visx Star S4 IR Excimer laser. Your personalised correction data is transferred to the computer of the laser delivery system. A "speculum" is used to prevent your eyelids from closing during the procedure. The corneal flap is gently lifted. The exposed corneal tissue is treated with the Excimer Laser. Advanced CustomVue treatment corrects the broadest range of vision imperfections possible, including mild-to-severe nearsightedness, farsightedness and all types of astigmatism. The treatment time is very short and it takes only seconds to deliver the treatment precisely. The 3d tracking system and Iris registration makes your best personalised vision precisely done even if you move your eyes during the procedure. If the eye wanders out of the tracking area the laser delivery automatically stops. The Iris registration also compensates for circular rotation of the eyes which normally occurs when you lie down. Other lasers don’t have this feature. The Visx Star S4 IR laser has the following unique features which makes it more advanced than other lasers:
- variable spot scanning (vss): variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times. the different size spots literally dance on the corneal surface sculpting your personal best vision just like an artist using different brush strokes-some broad some fine.
- variable repetition rate (vrr): vrr delivers treatment at varying repetition rates, optimizing treatment time and prevents pulse stacking and heating.
- ActiveTrak 3-d active eye tracking: captures all 3 dimensions of intra-operative eye movements. your cornea is dome shaped so this 3 dimensional tracking and delivery is critical. other lasers don’t have this 3d tracking.
Iris registration: locates the pre mapped iris land marks in your WaveScan and then automatically sets the treatment precisely placed. this iris registration is not present with other lasers.
After the procedure the flap is gently repositioned. Prior markings placed at the edge of the flip make the positioning of the flap accurate.
