What is the IntraLase?
The IntraLase Method is a 100% blade-free approach to creating the LASIK flap – the thin flap of tissue that the doctor folds back in order to perform the LASIK procedure.
Over 5 million procedures have been performed safely and effectively using the IntraLase method. And, in a clinical survey of LASIK patients who had their corneal flaps created using a microkeratome in one eye and the IntraLase method in the other, patients preferred the vision in the IntraLase treated eye 3:1 over the microkeratomes among those who stated a preference.
The IntraLase method enables the doctor to tailor the LASIK flap according to the shape of your eye. This is important because everyone’s eyes are shaped a little differently, and having a corneal flap that is individualized to your eye will help the doctor ensure that you get the best possible results.
Clinical studies show excellent visual outcomes and high patient satisfaction when the IntraLase method is used.
The creation of the corneal flap prepares the eye for the second step of the LASIK procedure, when another laser, known as an excimer laser, is used to correct vision.
Unlike other procedures, the IntraLase method creates the flap by applying tiny, rapid pulses of laser light – not a metal blade (microkeratome). Each pulse of light passes through the top layers of your cornea and forms a microscopic bubble at a specific depth and position within your eye that is determined by the doctor. As the IntraLase or iFS Laser moves back and forth across your eye, a uniform layer of bubbles forms just below the corneal surface. The doctor creates the corneal flap by gently separating the tissue where these bubbles have formed.
Because of the way in which the IntraLase method creates a precisely positioned layer of bubbles just beneath the surface of your eye, it creates a smooth, even surface after your flap is lifted. The flap is then folded back so then doctor can perform the second step of your LASIK procedure.
The IntraLase method of flap creation takes less than 15 seconds per eye. Including preparation time, the entire LASIK procedure typically takes about 15 minutes. Once the entire process is completed, the corneal flap ‘locks’ back into position.
The IntraLase laser which is available at Lee Hung Ming Eye Centre is the fifth generation laser which can create a corneal flap in under 15 seconds. The videos below show the difference in the speed of flap creation of an older generation of IntraLase and the fifth generation IntraLase which is used at Lee Hung Ming Eye Centre.
