The difference between da Vinci z-lasik femtosecond laser and Intralase femtosecond laser:

1. Manufacturer: Intralase femtosecond laser is the American IntraLase corp., Da Vinci is Swiss Ziemer Group;

2. Date of passing FDA certification: Intralase femtosecond laser was in 2002, and DaVinci z-lasik femtosecond laser was in 2006;

3. Number of installed machines : Intralase femtosecond laser has more than 1,200 units worldwide/more than 150 units in Asia, DaVinci z-lasik femtosecond laser has about 60 units worldwide;

4. Pulse frequency: Intralase femtosecond laser 15kHz or more, DaVinci z-lasik femtosecond laser Qi z-lasik femtosecond laser 1MHz;

5. Visualization: Intralase femtosecond laser cutting is visible throughout the cutting process, while da Vinci z-lasik femtosecond laser is invisible, which affects the discovery of problems during the surgical process;

6. Flap preparation time: Intralase femtosecond laser 22 seconds, Da Vinci z-lasik femtosecond laser 26 seconds (higher frequency means longer time)

7. Corneal flap cutting smoothness: Intralase The surface of femtosecond laser is smooth, while the smoothness of da Vinci z-lasik femtosecond laser is relatively poor and there are steps;

8. Corneal flap thickness setting: Intralase femtosecond laser 90?m ~ 400?m , increase or decrease by 1?m, IEK model can reach 1200?m, DaVinci z-lasik femtosecond laser 90?m, 110?m, 140?m;

9. Diameter setting: Intralase femtosecond laser diameter is 5.0~9.5mm, increasing or decreasing by 0.1mm. DaVinci z-lasik femtosecond laser is available in 4 types: 8.5, 9.0, 9.5, and 10mm;

10. Edge cutting angle: Intralase femtosecond laser 30~90° increases or decreases by 1° to reduce various complications related to the laminar knife. The da Vinci z-lasik femtosecond laser is fixed at 28°, which is similar to the mechanical laminar knife and loses the biggest advantage of the femtosecond laser;

11. Computer scheduling center: Intralase femtosecond laser can be accurately scheduled, but da Vinci z-lasik femtosecond laser cannot;

12. Clinical application: Intralase femtosecond laser Specialized in LASIK corneal flap production, Keratoplasty corneal transplantation, AK astigmatism incision, ICRS corneal ring implantation, DSEK endothelial transplantation, da Vinci z-lasik femtosecond laser LASIK corneal flap production.

13. Interruption of surgery: Intralase femtosecond laser can be re-operated immediately. Da Vinci z-lasik femtosecond laser is similar to lamellar surgery, and the patient needs to go home to rest.

14. Postoperative recovery: Intralase femtosecond laser recovery is 99% one day after surgery (skilled ones), da Vinci z-lasik femtosecond laser surgery is 99% recovery one day after surgery (skilled ones);

15. Others: Intralase femtosecond laser technology is the most mature, used by most doctors in the world, and has performed more than 2.5 million surgeries; together with VISX, it is known as iLASIK, the first brand, da Vinci z-lasik flying The Second Laser Corneal Flap has only two or three thicknesses to choose from. Approximately 2,000 eyes have been operated on around the world; its bladeless laser procedure is also called "Z-LASIK".
