Can nearsightedness be corrected?

In general, myopia (nearsightedness) can be corrected through various methods, but it currently cannot be completely cured.

The essence of myopia involves structural changes in the eye, such as an elongated axial length or abnormal corneal curvature, which prevent light from focusing precisely on the retina. Present medical techniques cannot reverse an elongated axial length or reshape the cornea, but vision can be "corrected" through optical or surgical approaches, enabling patients to see clearly without relying on glasses. Wearing eyeglasses or contact lenses can immediately compensate for refractive errors, while laser surgery reshapes the corneal tissue to alter its refractive power, achieving an effect similar to "built-in glasses."

However, it is important to note that all surgeries carry certain risks, and refractive surgery for myopia correction is no exception. Therefore, before choosing to undergo surgery for myopia correction, patients need to undergo comprehensive eye examinations to assess whether their ocular conditions are suitable for surgery. Additionally, after surgery, patients should follow medical advice regarding medication, maintain proper eye hygiene, and avoid strenuous activities to promote recovery and reduce the risk of complications.
