In refractive lens exchange the natural lens inside the eye is removed and replaced by a clear lens implant. The aim of the procedure is to give better vision without glasses. The implant lens is tailored to the size and shape of your eye, giving the opportunity to correct short sight, long sight and astigmatism. A standard lens implant is focused for distance, so that it is necessary to wear glasses for reading and other close work. An alternative is to use a multifocal lens implant that gives better vision for reading and other close work without glasses. These lenses have the ability to focus for both near and far. Most people are suitable for a multifocal lens, but there are some circumstances where it is not advisable. This will be discussed by your consultant.
The procedure is painless and takes about ten minutes. Local anaesthetic drops are used to numb the eye prior to the procedure. Usually the vision is improved by the next day, and continues to improve for at least several days.
In skilled hands modern lens exchange surgery is very safe, but as with all surgical procedures there are risks. These will be discussed by your consultant at your consultation.
