World State-of-the-art Instrument for refractive surgery——

Femtosecond Laser

Come to Beijing, Come to Mingzhong Eye Hospital

To friends who want to throw off your glasses of myopia, an epoch-making surgery is coming!

Top-level technology—Visx Star S4

　　 Visx Star S4 is the first excimer laser treatment device which passed the authentication of Food Drug administration of U.S.A., Ministry of Health and Welfare of Japan, and State Drug Administration of China. It has three dimensional full-automatic eyeball tracking system, which is the unique patent of VISX Incorporated U.S.A. It can track the very small movement of the eyeball, which makes the laser shot more accurate, the operation more safe, and the therapeutic effect better. The smart spot system can tailor the individualized keratectomy to the patient. It has the advantages of both variable spot scanning and flying-spot scanning, which produces more cornea-saving, shorter operation time, and more accuracy.

Perfect surgery—LEICA M844 ophthalmology operating microscope (Germany)

　　LEICA M844 ophthalmology operating microscope is a high quality microscope used in surgery. Its high achromatic lens can provide high quality picture and strength the transmission ability of light. It has high resolution and high definition light system. The three-dimension effect is better. The depth of focus is higher. It has a cold light source single fiber coaxial light emitter, with good brightness of the vision field. It has a foot control automatic fine focusing system, and a manual zooming system. Its outstanding stability and uncommon extending distance renders it easier to move in the operating room.

The inevitable pathway to individualized surgery——Wavefront Aberration System

　　Wavefront aberration is originally an astronomical technique, which used in military first. It is developed by National Aeronautics and Space Administration (NASA) to get clear astronomical photos through improving the phase difference problem produced during far-distance photograph. The investigation showed that the traditional refractive treatment of myopia can only deal with 85% phase differences in low frequency. The use of wavefront aberration technique in refractive surgery has brought revolutionary changes to traditional excimer laser surgery.

Let the operation more accurate and perfect——Iris Location System

　　Iris identification is the most advanced biological identification system in the world. The scientists in VISX Incorporated have developed the iris location system used especially in eye refractive surgery on the basis of iris identification technique. This system can record the circum movement of the eyeball of the patient during excimer laser surgery, track and compensate the rotation angle automatically. The tracking technique has been extended from XYZ three-dimensional tracking to four-dimensional rotational tracking, which improves the accuracy of the individualized excimer laser treatment of the myopia, astigmatism, and hyperopia.

Screen the latent keratoconus to protect the safety of the operation—OrbscanII Anterior Eye Segment Analysis System

　　OrbscanII Anterior Eye Segment Analysis System is the only inspection system to probe the post-surface and thick distribution of the cornea, which makes it the key standard of cornea thorough examination and keratoconus screening before refractive surgery. It has placido disc system to measure the refractive power of the corneal surface, during which the document produced can be combined with the data from Wavefront Aberration System, to provide true document of the individualized keratectomy. It can be connected with the laser to carry out individualized keratectomy to guarantee the safety and effectiveness of the surgery.
