Semi-femtosecond Refractive Surgery is a personalized laser myopia surgery guided by corneal topography, which results in a better quality of vision and minimizes the occurrence of glare.
Like a fingerprint, each person’s cornea is unique, with a different shape and texture called “corneal topography”. Semi-femtosecond Sculpture Surgery is an individualized procedure based on the higher-order aberrations shown on the patient’s corneal topography, thus effectively eliminating the individual’s low-order aberrations that affect vision and the higher-order aberrations that affect visual quality, and dramatically improving the patient’s quality of vision.
Refractive errors such as myopia and astigmatism are low-order aberrations that affect visual acuity, while high-order aberrations such as astigmatism affect visual quality. Semi-femtosecond laser surgery corrects low-order aberrations such as myopia and astigmatism, and at the same time, it can also correct higher-order aberrations according to the guidance of the corneal topography to improve visual quality and reduce the phenomenon of glare.
It is recommended that patients follow the doctor’s instructions for care after Hemifacial laser surgery, have regular checkups, and consult the doctor promptly when discomfort occurs.
