04-IntraLase® LASIK

During LASIK surgery, a flap is created in the outer layers of the cornea. The flap is hinged and lifted so the excimer laser can treat only the underlying layer of the cornea. This circular flap remains attached to the cornea by a small hinge of tissue. The hinge enables the flap to be lifted away from the central cornea. A laser can then be used to reshape the exposed mid-layer of the cornea.

1. what is the IntraLase Method?

The IntraLase Method is a 100% blade-free approach to creating your LASIK flap – the thin flap of tissue that the doctor folds back in order to perform your LASIK procedure. Traditionally, LASIK doctors have used an instrument called a microkeratome for the creation of LASIK flaps. The microkeratome is a hand-held blade that moves across the eye, cutting the LASIK flap as it goes. LASIK is extremely safe, but if complications do occur, the microkeratome is frequently the cause. The IntraLase Method, by contrast, is a 100% blade-free approach to corneal flap creation - enabling your doctor to create an individualized LASIK flap without a blade ever touching your eye.

2. How does the IntraLase Method work?

The IntraLase Method uses tiny, rapid pulses of laser light to create your corneal flap — instead of using a metal blade — during the first step of LASIK. 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. The IntraLase laser moves back and forth across your eye, creating a uniform layer of bubbles just beneath your corneal surface. Just prior to applying laser vision correction, the doctor creates your corneal flap by gently separating the tissue where these bubbles have formed. The corneal flap is then folded back so the doctor can perform the second step of your LASIK treatment.

3. What is the difference between a corneal flap created with the IntraLase Method and one created with a microkeratome?

The microkeratome is a hand-held instrument, which contains a steel blade that moves back and forth and creates a cut as it travels across the cornea. A microkeratome is only capable of making a single, one-dimensional cut across the cornea. As it cuts, the blade oscillates back and forth, which can leave an irregular surface after the flap is lifted. This can affect the quality of your postoperative vision. Because of the unique 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. With the IntraLase Method, a blade never touches your eye.

4. Is the IntraLase Method painful?

Prior to creating the flap, the doctor applies drops to numb the eye, and then applies a special ring and an instrument that gently flattens your cornea in preparation for the IntraLase Method. This part of the process is not painful — patients report feeling only slight pressure.

5. Is it right for me?

If you're looking for blade-free treatment that virtually eliminates the most severe sight-threatening complications, the answer is yes. The IntraLase Method also delivers outstanding visual results: more patients achieve vision that is 20/20 or better when the IntraLase Method is used.1 And patients report better quality of vision overall, particularly in terms of their ability to see well in low light, such as at dusk or at night.

6. What else should I know?

Preferred by patients. In a clinical survey of LASIK patients who had their corneal flaps created using a blade in one eye and the IntraLase Method in the other, the vision in the IntraLase-treated eye was preferred 3-to-1 (among those who stated a preference) Proven and trusted. Hundreds of thousands of procedures have been performed safely and effectively using the IntraLase Method. The most advanced treatment there is. Advanced IntraLase technology gives your doctor the highest degree of surgical control for the most effective procedure you can have. Ultimately, the 100% blade-free IntraLase Method gives patients more confidence andless anxiety going in for LASIK treatment, and excellent vision coming out.
