Does cataract surgery change the shape of the eye?

Cataract surgery itself does not change the overall shape of the eye. The procedure involves removing the cloudy lens and usually replacing it with an artificial intraocular lens (IOL), which can affect the eye's optical properties but not its structural shape. While the surgery can improve vision by restoring clarity, the anatomical structure of the eye remains largely unchanged. However, changes in vision post-surgery can sometimes create a perceived difference in how the eye functions.
