Nearsightedness in one eye and farsightedness in the other can theoretically be corrected by femtosecond surgery, but there are other factors that need to be taken into consideration as to whether or not it can be performed.
Femtosecond laser is a common treatment for refractive errors, not only for myopia, but also for hyperopia and astigmatism. The principle is to change the refractive state of the cornea through the use of femtosecond laser. Patients with myopia in one eye and hyperopia in the other eye can theoretically be corrected by femtosecond surgery.
However, whether femtosecond laser can be implemented or not needs to consider other factors, such as corneal thickness, degree of refractive error, corneal morphology and so on. Patients are advised to go to the ophthalmology department of the hospital for examination in time, and the doctor will design a specific surgical plan according to the current refractive state of the patient’s eyes and eye conditions.
