ICL lens implantation and femtosecond are two types of vision correction surgeries, with different surgical methods and indications. There is no one surgical method that is better than the other, only the patient is more suitable for which surgery. 1. ICL lens implantation: It is an intraocular surgery, in which an artificial lens is implanted in the posterior chamber to improve the refractive power of the eye. The surgery is reversible and the IOL can be removed or replaced. It is suitable for people with moderate to high myopia and those who are not suitable for corneal surgery, such as those with thin corneas. 2. Femtosecond: The full name is corneal full femtosecond laser surgery, which refers to cutting the cornea by full femtosecond laser to thin the thickness of the cornea and correct the vision. With low damage and quick recovery, the surgery is suitable for people with moderate or low myopia and those who pass the corneal thickness examination. The two surgeries have their own advantages in correcting vision. It is recommended to go to regular hospitals for corneal topography, optometry and other examinations to choose the appropriate surgical method to ensure the safety of the surgery.
