What is a cataract lens?

Cataract lens power usually refers to the degree of intraocular lens implantation required for cataract surgery. Generally, doctors will calculate the degree of intraocular lens through various examinations before surgery. After the appropriate intraocular lens is implanted in the eye, the refractive state of the eye can be normal and the postoperative vision can be restored. If the intraocular lens power is not appropriate, it will affect the effect of surgery. After surgery, we should pay attention to rest, do not be too tired, ensure adequate sleep, keep eyes clean and hygienic, prevent infection, and check on time after surgery.
