Eye Lasik
Eye LASIK is intralace femtosecond laserFlap preparation usingAdvanced Vision correction surgery using the CustomVue system (wave scan + Star S4 IR excimer laser). Utilizing both technologies, we create a custom-made treatment program for each eye.It is an excellent technology that corrects the distortion of the entire eyeball that can deal with irregular astigmatism that affects normal vision. Visual acuity is good and can be seen immediately after surgery.
For those who have given up on LASIK
Compared to Wavefront LASIK, which uses a microkeratome, the flap can be created more precisely and thinly, so it is suitable for people with thin corneas who gave up LASIK before. In general, the microkeratome can only reduce the flap thickness to 120 μm, but the femtosecond laser can reduce the flap thickness to 90 μm. The edge is also incised at a special angle, so that when the surgery is completed and the flap is put back, the flap fits exactly where it should have been on the cornea.

Intralace Femtosecond Laser (FS Laser)
LASIK Flap Fabrication Laser Equipment
To date, more than 5 million cases of surgery using the IntraLase Femtosecond Laser have been performed worldwide. Reducing complications, irregular astigmatism, and maintaining a thick cornea are essential factors for successful refractive surgery. The IntraLace femtosecond laser produces flaps of precise and uniform thickness.

wave scan
Using a high-precision Hartmann-Shack wavefront sensor, data is collected and analyzed from approximately 240 data points to quickly and accurately determine the distortion of the patient's entire eye. measurement
Not only the distortion of the cornea, but also the distortion of the entire eyeball is analyzed and measured with high precision. It faithfully analyzes and reproduces the distortion of the entire eye from the measured data, making it possible to correct higher-order aberrations in treatments using advanced custom views. This exerts a strong effect on astigmatism correction, which affects postoperative vision. Wavescan also has an iris registration (IR) that enables accurate laser irradiation to recognize and register the iris pattern during measurement.
Star S4 IR® Excimer Laser
Better Laser Systems for More Patients
Technologies such as Iris Registration (IR), Variable Spot Scanning (VSS) and Variable Repetition Rate (VRR®), and 3D Active Eye Tracking enable the Instruments for refractive corneal surgery (LASIK and PRK) and therapeutic keratotomy (PTK) with advanced custom view technology that optimizes the time and precision of surgery. text.

■ Functions of Star S4 IR® excimer laser
アイレス レジストレーション（IR）
虹彩認識登録システム
術前検査は座った状態で測定しますが、手術は横になっていただきます。そうしますと、眼球に自然に回転が生じます。虹彩模様認識登システムは姿勢が異なることで生じる眼球の回転、瞳孔の中心移動の補正を行う技術です。この自動補正が、正確なレーザー照射を可能にします。
ウェーブスキャンとの連携により眼球の状態を正確に把握し、エキシマレーザーを照射します。この高度な技術によって、視力回復のみならず、見え方の質を向上させ、ハロ・グレア（主に夜間、光がにじんで見えたり、まぶしく感じること）を軽減させることができます。
可変スポットスキャン 可変反復率
ダメージを最少にしつつ正確な照射を
照射回数を変化させ、安全な治療スピードを保ちながら効率よく、レーザーの照射位置・照射回数を最適化します。これにより、レーザー照射で生じる熱の角膜への影響を最小限におさえながらレーザーの照射径を調節することで、角膜の収差（光線が一点に集まらずに像がぼやけたりゆがんだりすること）も少なく角膜を正確に切除します。
3Dアクティブアイトラッキング
3次元自動眼球追尾システム
この技術は自動センタリング機能を備えており、立体的に眼の動きを捕捉します。レーシック手術中に眼球運動によって多少瞳孔が動いたとしても、正確に角膜を削ることができます。レーザー照射1回につき3回ものチェックを行うため、正確なレーザー照射を実現します。
■ Air LASIK's thin and uniform flap creation technology
Corneal thickness = flap thickness + corneal floor (residue after flap is made)
The thicker the corneal bed, the stronger the eye. Below 275 microns, the cornea may deform.

As shown in photo A, Eye LASIK has less blurring at night, and as shown in photo C, it provides a clearer field of view.
Eyesight and Satisfaction with Eye LASIK (Material provided by AMO, USA)
Eye LASIK is LASIK that pilots and astronauts can also undergo. He was approved as a fighter pilot by the US Department of Defense in December 2006, as an astronaut by the National Aeronautics and Space Administration (NASA) in September 2007, and as a fighter pilot by Canada in February 2009.
