Why do I need an intraocular lens after cataract surgery?

Cataract

is a common eye disease characterized by clouding of the natural lens in the eye, resulting in decreased vision. The main treatment for cataracts is surgery, which removes the clouded natural lens to eliminate the condition. Removing the natural lens alone does not restore vision, because the lens plays a very important refractive role in the eye. Without the lens, light cannot be focused accurately on the retina, and the patient still has blurred vision. Therefore, at the same time as or after the removal of the natural lens, intraocular lens implantation is needed to enable the light to be accurately focused on the retina again. In this way, the patient's vision can be restored or improved, and the quality of life can be greatly improved. At the same time, intraocular lens has good biocompatibility and stability, and can function safely in the eye for a long time.

Patients need to visit the hospital regularly after surgery to confirm their physical condition.
