Who can introduce the difference between full femtosecond and half femtosecond in Zhengzhou Puri?

Full femtosecond and half-femtosecond difference is the following, 1, the difference in price, full femtosecond is the most advanced laser technology, because of its relative stability, the price is much more expensive than half-femtosecond; 2, the difference in the way of surgery, half-femtosecond laser is used in the corneal flap surgery, is the U.S. Space and Aviation Administration (U.S. NASA) designated for the enhancement of the U.S. astronauts vision of the surgical procedure, the surgical process is completely laser to complete, there is no knife involved. The process of the surgery is completely done by the laser, without the involvement of the knife, and the production process is femtosecond flap-making - excimer laser cutting - reset, and the end of the surgery. The full femtosecond laser makes two separate laser scans at different depths in the corneal stroma to form a complete convex lens shaped corneal tissue, and then makes a small 2-4mm incision at the edge of the cornea with a special instrument. Then take out the corneal tissue made before. 3, equipment difference, Zhengzhou Purui Eye Hospital's full femtosecond laser uses Germany Zeiss original imported equipment, the entire surgical process is completed on a single device.
