The decision of which is better, femtosecond or crystalline lens implantation, needs to be based on the patient’s eye condition and there is no clear-cut advantage or disadvantage. Femtosecond surgery is a procedure that emits laser light in pulses lasting only a few femtoseconds, and is commonly used to correct myopia. Generally speaking, femtosecond surgery is not suitable for those with myopia of more than 1,000 diopters, and the cornea is too thin for femtosecond laser surgery. Lens implantation, also known as crystalline lens implantation, is one of the most common clinical procedures for myopia correction. IOL implantation can be applied to patients with ultra-high myopia. If the patient is older than 55 years old, has shallow anterior chamber, or has eye diseases, it is not suitable for IOL implantation. It is recommended that myopic patients consult a regular hospital to assess their condition and choose the appropriate treatment under the guidance of a doctor.
