After cataract surgery, glasses are usually required depending on the recovery of vision. Cataract can be restored through surgical treatment, the principle is to remove the cloudy lens inside the eye, and then implant a transparent artificial lens, to remove the cloudy refractive interstitium to block the light, so as to restore vision. After cataract patients are treated by surgery, the regulation function of the eyes is imperfect, and they are in the state of phakic vision. At this time, they need to wear near glasses, which is often called presbyopia, to see clearly when they look at the near future, so they need to be equipped with spectacles after surgery. In addition, some patients still have residual astigmatism after surgery, or myopia, hyperopia and other conditions, see far will not be too clear, which also need to wear glasses to correct. Generally speaking, glasses are prescribed about 3 months after surgery when the refractive state of the eye has stabilized. It is recommended to consult your doctor and follow the doctor’s instructions as to whether, what and when to wear glasses after cataract surgery.
