Precision Femtosecond Laser Surgery and Full Femtosecond Laser Surgery each have their own advantages and disadvantages for different types of patients, and it is not easy to simply say which one is better.
The main advantage of the FSL procedure is the ability to remove the patient’s high-order phase aberrations, but the disadvantage is that a corneal flap needs to be created, and the surgical incision is a bit larger than that of the full femtosecond laser procedure. It is usually suitable for patients who have more significant higher-order aberrations after corneal topography.
The main advantage of full femtosecond laser surgery is that it does not require a corneal flap, so the surgery is less invasive, the recovery is faster, the patient’s comfort is higher, and it is less prone to complications such as flap displacement after the surgery. The disadvantages are that the procedure is a bit more expensive and does not eliminate the patient’s higher order phase difference. It is suitable for patients who have undergone corneal topography and do not have significant high-order aberrations.
Patients with refractive error who wish to have it corrected by surgery must first go to the ophthalmology department of a hospital for a comprehensive examination, where the doctor will evaluate the patient’s eye condition and then guide a specific treatment plan.
