IntraLASIK is a form of refractive eye surgery that is similar to LASIK. It creates a corneal flap with a femtosecond laser microkeratome rather than with a mechanical microkeratome, which uses a blade. The difference between LASIK and IntraLASIK is the method by which the corneal flap is created. IntraLASIK can be used to surgically create monovision to improve your ability to see objects both near and far.
A LASIK flap created with a femtosecond laser is regarded by many ophthalmologists as an improvement over traditional LASIK because of a greater accuracy in flap size, shape, and thickness.
Kaskaloglu Eye Hospital uses the IntraLase FS Laser, which has a computer-controlled laser that creates the corneal flap for LASIK. This provides unprecedented control and the ability to customize the flap for each of our patients.
That is a femtosecond Laser?
A femtosecond laser is an infrared laser that can treat tissue very precisely with significantly less heat created than other laser treatments , a big advantage in eye laser surgery. Femtosecond lasers work with ultra-short impulses of light (10-15 seconds) that last only a quadrillionth of a second to create a spot as tiny as 1/100mm.
What can the femtosecond laser be used for?
The laser is used to treat patients with thinner corneas or those with more severe nearsightedness or farsightedness. It can also be used to treat patients with opacities or warped areas of the cornea.
How It Works
To make the corneal flap, the IntraLase FS60 Laser is focused into a tiny spot of energy that passes harmlessly through the outer layers of the cornea until reaching its exact focal point within the central layer of the cornea. There, the corneal flap procedure is initiated, silently and painlessly, with remarkable precision. Contrary to traditional lasers, the energy of the laser beam from a femtosecond laser doesn’t affect the tissue on the surface of the cornea, but rather reaches a specific predetermined depth inside the cornea.
You will not be able to see the laser and the procedure only lasts about 40-50 seconds per eye.
The IntraLase FS Laser can also be used to create the channels and entry cuts for placement of Intacs. Using the IntraLase FS Laser for this procedure assures that the two segments are placed at the exact same depth and removes the need for making the more surgically difficult mechanical channel.
Why we’ve invested in the IntraLase FS Laser:
IntraLASIK provides our patients with an extra margin of safety by eliminating potential complications from mechanical microkeratomes. This procedure allows us to perform LASIK on patients with thin corneas because we can make a more precise shallow flap, which allows us to correct higher levels of refractive error. It also provides both the patient and the surgeon with a higher level of confidence knowing the creation of the flap will be without complications.
The corneal flap procedure with IntraLASIK using the IntraLase FS Laser is painless and more comfortable as there is much less pressure placed on the cornea with the laser versus the mechanical microkeratome.
