Presbyopia is a natural ageing phenomenon that leads to difficulty with near vision and reading after the age of 40. Presbyopia occurs because the natural lens within the eye becomes stiffer and loses it's ability to accommodate. To be able to read people typically require plus powered reading glasses. Stiffening of the lens is the beginning of an ageing process that will eventually lead to cataract. People who are long-sighted will typically find that they require glasses for near and far vision earlier than those who are short-sighted. 

With the development of sophisticated multifocal lenses it is possible to simulate the visual range of the young natural lens, as well as correct distance vision. This typically restores near, intermediate and distance vision without the need for glasses in most cases. Refractive lens exchange (RLE) also known as Clarivu is based on the established proven technique of cataract surgery, but is performed before formation of cataract. During RLE/Clarivu the natural lens is removed through a keyhole incision and a multifocal intraocular lens is implanted into the eye. Surgery is usually painless and recovery is rapid. Further cataract surgery is not required after RLE.

Ms de Benito performs RLE surgery using the Lensar femtosecond laser for ultimate precision and safety. She uses the Zeiss AT-LISA trifocal, AMO Symfony and Alcon Panoptix lenses for the best possible optical results. A small number of patients may require laser eye surgery for bespoke refinement of vision. Ideal patients are over 50 years old.
