Excimer laser keratomileusis is an extremely precise miniature corneal lamellar cutting system referred to as a keratome; the latest technology uses a femtosecond laser to create a corneal flap with a tip on the corneal surface. The excimer laser is then used to precisely vaporize the corneal stroma under the flap for cutting purposes, thereby changing the shape of the anterior corneal surface and adjusting the refractive power of the cornea so that external light can accurately converge into an image at the base of the eye to correct myopia. Second, da Vinci Femtosecond Laser and Eagle Vision Blue Tone Cool Eye Excimer Laser together is the best combination in the world: it takes less than 10 minutes to complete a femtosecond excimer laser surgery, which cannot be achieved by any other matching models. Advantages of the da Vinci Femtosecond Laser: The da Vinci Femtosecond Laser takes only 12 seconds to complete flap making. Patients do not need to wait, and do not need to change beds. In a completely “knifeless” situation, the laser creates a highly accurate corneal flap and ablates the cornea with the excimer laser, truly realizing a “full knife free surgery”. In the morning, you can go to work in the afternoon! Femtosecond laser advantages 1, the whole knife, to eliminate infection: Femtosecond laser is an all-laser surgery, without the use of corneal lamellar knife, to eliminate the possibility of cross-infection and residual debris. 2, small flap making error, higher safety: Femtosecond laser flap making precision control in 10-15 microns, postoperative safety is more guaranteed. 3, precise flap making, more comfortable after surgery: corneal flap cutting accurate, less damage to nerves and blood, femtosecond laser surgery, eye dryness symptoms significantly reduced. 4, uniform flap making, better post-operative visual quality: avoid irregular astigmatism caused by uneven flap cutting, improve post-operative night vision and glare problems. 5. Faster post-operative recovery: Femtosecond laser recovery time and recovery effect are faster. Femtosecond laser surgery is an option for patients who cannot undergo traditional surgery because their myopia is too deep or their cornea is too thin.
