| About the laser speed of SMILE LASIK |
As new vision correction equipment using the lenticule extraction method from various manufacturers has emerged, many people are curious about how they differ from VisuMax, the equipment used for SMILE LASIK.
One of the most notable comparison points is the laser speed of each surgical device. Typically, people tend to simply compare the MHz or kHz speed of the laser. However, we would like to point out that this speed difference should not be evaluated based on just one factor.
In all laser vision correction equipment, including VisuMax for SMILE LASIK, the commonly expressed laser speed refers to the "laser repetition rate." This does not indicate the actual laser irradiation speed or the irradiation time. Instead, the overall laser scanning speed must be considered comprehensively.
In other words, the surgery time and the superiority of the equipment cannot be determined solely by the laser repetition rate. These two speeds—repetition and scanning—are factors that should be calculated together, as the comprehensive laser speed has a significant impact on the surgery. This helps reduce the time patients need to focus and minimizes damage caused by the laser.

In addition to fast laser irradiation time, laser accuracy is also crucial. For stable surgical results and to minimize eye damage, the laser must be precisely targeted at the correct position.
Zeiss' scanning technology is so precise that it could hit a coin on the surface of the moon from Earth. This accuracy ensures that the laser forms the most ideal lenticular shape at consistent intervals.
We hope this helps patients better understand laser speed. We will continue to bring you more in-depth discussions on SMILE LASIK.
Thank you for your time!
