Why does the eye cornea have to be replace with catract surgery?

During cataract surgery, the eye's cloudy lens is removed and often replaced with an artificial intraocular lens. While the cornea itself is not typically replaced during this procedure, it may be affected if there are underlying conditions or if the surgery causes complications. If the cornea becomes cloudy or damaged, a corneal transplant may be necessary, but this is separate from the cataract surgery itself. The primary goal of cataract surgery is to restore clear vision by addressing the lens, not the cornea.
