Astigmatism in cataract patients after surgery usually does not return on its own and requires correction with glasses or laser surgery. Astigmatism after cataract surgery is called surgical marginal astigmatism and is usually caused by changes in the curvature of the cornea due to the incisions made during surgery. In most cases, this astigmatism is not severe enough to affect the patient’s vision much, and this astigmatism usually does not recover on its own. However, if the patient’s vision is significantly reduced due to astigmatism of surgical origin, it can be corrected by wearing glasses, or if the patient is not willing to wear glasses, laser surgery can be considered. If astigmatism occurs after cataract surgery, patients should go to the ophthalmology department of the hospital in time for examination, to clarify the severity of the current condition, and the doctor will formulate a reasonable treatment plan.
