This is done using an ultrasonic probe through a small incision in the cornea or clear window of the eye. The operation aims to leave behind the bag, or capsule, of the cataract to act as a support for the intraocular lens. The intraocular lens does not require cleaning or wear out, and the modern foldable intraocular lenses enable the operation to be performed through a much smaller wound, meaning fewer restrictions for you after the operation.
