LASIK procedure

There are many ways to correct myopia. We believe that it is desirable to select the optimal surgical procedure that suits the individual, such as the presence or absence of astigmatism and the thickness and strength of the cornea.

Medical equipment used in LASIK

Femtosecond laser: a device (laser) that creates a flap
Microkeratome: A device (blade) that creates a flap
Wavescan: measure and analyze eye strain
S4IR: Corrective Corneal Laser

About the flap

The flap protects the post-operative scars, reducing post-operative pain and speeding up the recovery of visual acuity. It is in a stable state after 3 months due to the suction force with the corneal endothelium.

Features of laser-fabricated flaps

Created with a microkeratome (blade)

Created with a femtosecond laser

・The cross section is clean

・Uniform, thin, high-strength flap

・There is little irregular astigmatism, and from the next day

The appearance is dramatically better.

・Flap fits well and does not slip off easily

・Complications are reduced

Benefits of Eye LASIK

■Surgery that can correct high-order aberrations

Higher order aberration is a technical term for eye distortion. When high-order aberrations increase, objects appear blurry. If you want to make the image clear and easy to see, it is necessary to reduce high-order aberrations. iLASIK makes this possible. Eye LASIK reduces this high-order aberration by creating a flap with a laser and making full use of the wavefront laser system. This system allows you to create a clearer field of view.

■ The difference between custom-made LASIK and conventional LASIK

Custom-made LASIK is Eye LASIK and Wavefront LASIK. Femtosecond LASIK becomes Conventional LASIK.

If you compare both types of LASIK to shoes, would custom-made LASIK be a shoe made by making a wooden mold of your own foot, and conventional LASIK be a ready-made shoe? Small fitting will be different.

■ Wave scan with important points for successful LASIK

① Astigmatism can be corrected

Astigmatism greatly affects postoperative vision. In order to correct this, it is necessary to measure the distortion of the entire eye with high precision during the inspection stage (order-made). Wavescan is used for this measurement. Highly accurate correction data including astigmatism is created.

(2) 3D active track function that corrects artificial misalignment during surgery

In any surgical procedure, laser irradiation is used to correct myopia, but during surgery, even the slightest movement of the line of sight can cause the eye to move, causing the center to blur. Aligning the laser manually to minute eye movements can be difficult. The 3D active track function is a function that the machine corrects even a slight artificial deviation and follows it correctly.

3. Automatic correction of eye rotations that cannot be adjusted by human hands IR function

Posture during examination is different from posture during surgery. When a person lies on their back, their eyes rotate (rotate), and the angle of astigmatism in the test data is automatically adjusted to that state (the test data is measured while sitting).

This wavefront laser system, which measures slight distortion with high precision and reliably connects the data to laser irradiation, is necessary to reduce high-order aberrations and achieve a higher quality field of view than conventional vision. will be

High-order aberrations are small and clearly visible

High-order aberrations appear large and blurry
