Cataract surgery is performed to remove the cloudy lens (cataract) in your eye and replace it with a clear, artificial intraocular lens to allow clear vision to be restored. In refractive lens exchange however, instead of removing a cloudy lens, your natural clear lens is removed for the purpose of correcting the refractive (focussing) power of your eye to achieve spectacle independence. This procedure is also known as a clear lens exchange.
The surgery itself is exactly the same; however, the terminology allows for distinction between removal of a cloudy versus a clear lens.
