Modern cataract surgery not only restores the clarity of the optics in the eye but allows access to lens implant technology which can improve the focusing of the eye.
Not only can the cloudy lens be removed restoring a clear view of the world, but also the astigmatism of the eye can be addressed.
The higher order aberrations of the eye can be optimised and for many people, clear vision for near can be achieved in addition to clear vision for distance. Many of these patients no longer need to wear glasses after their cataract surgery.
