What is LASIK?
LASIK is the most attractive refractive procedure as an alternative method to contact lenses and glasses. The method uses a medical laser on the cornea to change its shape, to better focus light onto the retina of the eye, improving vision as a result. Since its effect shows up immediately after the surgery in the U.S., it is known as a popular way to correct eyesight with 1.3 million people undergoing the surgery every year. Here in Japan, the method is also spreading rapidly. What is the IntraLase Method?
The Femtosecond laser is a 100% blade-free technique used to perform the critical first step in the LASIK procedure: creating the corneal flap. The creation of the corneal flap prepares the eye for the second step of the LASIK procedure, in which an Excimer laser is used on the inner cornea to correct vision.
How does the IntreaLase Method work?
The Femtosecond laser 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 Femtosecond 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.
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. With Femtosecond laser, it creates a smooth surface after your flap is lifted and a blade never touches your eye.
At Shinagawa LASIK Center, we offer the highest level of treatment possible with efficient staff members. We provide doctors with recognized surgical skill, clinical engineering technologists, and optometrists who properly manage the maintenance of the laser and other optical equipments.

The process of surgical operation
 |
Local anesthesia is applied. |
 |
By irradiating the Femtosecond laser, a flap (lid) is produced. |
 |
By irradiating the Excimer laser, the refraction index of cornea is changed. |
 |
After using the Excimer laser, the flap is repositioned and sterilized. |
