What is the difference between excimer laser surgery and femtosecond laser surgery?

Abstract: what is the difference between excimer laser surgery and femtosecond laser surgery? Ophthalmologists said that the difference between excimer laser surgery and femtosecond laser surgery is that femtosecond laser surgery completely abandons corneal scalpel and truly realizes “whole process knife free surgery”.

excimer laser surgery and femtosecond laser surgery are the mainstream myopia surgery at present. Patients with myopia will have questions. The therapeutic effects of excimer laser surgery and femtosecond laser surgery are good, so why is the price of femtosecond laser surgery so expensive? What is the difference between excimer laser surgery and femtosecond laser surgery? Now let’s get to know.

excimer laser surgery

femtosecond laser surgery is a full laser surgery of corneal flap. It does not need to use mechanical blade to make corneal flap. It can make corneal flap with very accurate thickness and smoother surface. In the process of surgery, it can eliminate almost all serious complications caused by corneal flap making. It will not cause cross infection, high safety, and almost no corneal flap displacement, dissociation and fragmentation. Therefore, it can reduce glare and ghosting after operation. From the current femtosecond laser surgery, no serious complications related to the operation have been found.

and

compared with femtosecond laser surgery, conventional excimer laser surgery uses mechanical corneal lamellar knife to make corneal flap. It needs to operate on the anterior stroma of cornea to fundamentally change the corneal curvature and reshape the corneal radian. The operation principle is to make an upper flap of about 50mm by using alcohol or other physical methods, Precise grinding under the epithelial flap with excimer.

and

for myopic patients, they certainly need to choose safe, comfortable and no worries to complete the operation. From anatomy to physics, from manual to computer, from knife to knife, femtosecond laser is the inevitable trend of medical development. The emergence of femtosecond laser makes human beings leave the scalpel in corneal surgery for the first time, truly realize the “whole process knife free surgery”, and push the laser myopia surgery to a more accurate, safer and clearer new height.

different surgical methods are suitable for different people. There is no best, only the most suitable. Therefore, you don’t have to worry. As long as you check before the operation, the doctor will help you choose the most suitable operation method according to your data.
