To know what kind of excimer to choose, we must first understand some knowledge: as long as qualified excimer can generally meet the requirements of sight distance (increase the number of lines in the eye chart); But in addition to looking at the distance index, the vision should be comfortable and lasting. Good contrast sensitivity and glare sensitivity. The technical difference of excimer equipment is mainly in the indicators that affect the visual quality.

Therefore, when choosing the brand and model of excimer laser, we should mainly look at:

1, is it a real small spot high frequency laser? It is easy to understand that the smaller the spot, the thinner the carving knife and the more details of carving. Therefore, the higher the pixel of the visual object. Just like a camera with higher pixels, the higher the picture quality.

2. Can this excimer guide the Q value, because our corneal surface is not completely spherical, and everyone's surface shape will be slightly different. Q-lasik surgery can cut the cornea individually according to the aspheric characteristics of the individual cornea (Q-value data), and maintain the natural aspheric characteristics of the cornea after operation. It changes the shortcoming that the previous surgery can only improve the vision but not the visual quality, so that the patients can recover their normal vision and greatly improve the postoperative visual quality, and avoid glare and night vision decline.

The above two technical characteristics are the most important, so at present, the models that can meet the above conditions are mainly: Hawkeye Blues Cool Eye Excimer exported by khoikhoi Company. So it's best to choose this one as the quasi-molecule, the latest one. Hawkeye Blues Cool Eye is a new generation product of Hawkeye Century Wave.
