What is all femtosecond laser myopia surgery

Abstract: all femtosecond laser small incision stromal lens removal does not need to make corneal flap. Femtosecond laser is used to make corneal flap stromal lens, and then the lens is removed through a 2-4mm incision, which can reduce the damage to corneal nerve fibers, greatly reduce postoperative dry eye symptoms, maintain corneal biomechanics and stability, and improve visual quality.

what is full femtosecond laser

it uses the characteristics that femtosecond laser can focus accurately in ultra-fine space to make a uniform, smooth and perfect stromal lens in the corneal stromal layer according to the data of patients’ preoperative examination, and then take out the corneal stromal lens through a small incision.

all femtosecond laser surgery process

all femtosecond smile laser micro incision lens removal. Firstly, according to the myopia of myopia, a corneal stromal lens with corresponding thickness and a micro corneal incision are made with femtosecond laser. Then take out the prepared corneal stromal lens through a small corneal incision. After taking out the corneal stromal lens, the refractive power of the cornea has been accurately reshaped, so as to achieve the purpose of correcting myopia. Advantages of

and

all femtosecond laser

and

1. The whole process is femtosecond without removing the flap. It is more minimally invasive. The whole operation of

and

is completed by one femtosecond laser equipment. There is no need for laser to make corneal flap, remove corneal flap, or combine with excimer laser for oxidative cutting of corneal stroma.

2. The innovative smile minimally invasive technology improves the visual quality.

3. Ensure the natural physiological state of cornea and better effect.

and

adopt the concave contact lens with arc design of “simulating human cornea” in femtosecond, abandon the traditional corneal flattening cone, ensure the natural physiological state of cornea during operation, accurate cutting and better postoperative effect.

4. Low negative pressure without amaurosis, fast and comfortable

combined with visumax’s unique concave contact lens can achieve effective and stable low negative pressure corneal suction during operation, avoid temporary vision loss or amaurosis caused by elevated intraocular pressure during routine operation, and reduce the psychological burden of patients; In addition, the whole femtosecond operation is only tens of seconds, which is safer and more comfortable.

5. Full femtosecond can also be used for half femtosecond surgery and personalized flap making. With higher safety,

full femtosecond technology can accurately control the thickness, size, pedicle width and angle of corneal flap edge. It improves the safety and predictability of surgery.
