Any surgery has the possibility of failure, and so does femtosecond surgery, i.e., the vision after femtosecond surgery does not meet the expected results, and the patient still needs to wear glasses, or even has lower vision than before the surgery.
Femtosecond surgery mainly refers to the use of laser to vaporize the eye tissues to change the refractive ability of the cornea, resulting in the correction of myopia. Femtosecond surgery is more effective in treating myopia, the success rate is higher, and you do not need to wear eyeglasses after a successful surgery. The success rate of femtosecond surgery in treating myopia is not 100% and therefore there is a possibility of failure.
Some patients still have residual refractive error after the surgery, which cannot achieve the effect of improving vision, and need to continue to wear glasses. Patients who should pay attention to eye hygiene after surgery, reduce the use of electronic products to avoid eye irritation, which is conducive to post-surgery recovery and stabilization of the surgical effect.
It is recommended that patients after femtosecond laser surgery follow the doctor’s instructions for care, regular review, and timely consultation after discomfort occurs.
