In Lens Exchange Surgery the natural lens of the eye is removed and replaced by a plastic lens. The aim of this procedure is to alter the refraction (or focus) of the eye by removing the natural lens of the eye and replacing it with a plastic artificial lens.
Before the operation the eye needs to be measured in order to calculate the optical power of the intra ocular lens implant that is needed to achieve the desired change in focus of the eye. The measurements are quick and simple.
Lens exchange is a surgical procedure for the correction of short sight (Myopia) and long sight (hyperopia) and is an alternative to LASIK, LASEK and PRK laser refractive surgery.
Lens exchange is also sometimes called 'Refractive Lens Exchange', 'Clear Lens Extraction' and 'Presbyopic Lens Exchange'.
The eyes of some patients are not suitable for laser refractive surgery. The usual reason is that the degree of short or long sightedness is too large to be safely or effectively corrected using a laser procedure. Also some patients do not like the concept of laser treatment of the eye which does involve the irreversible removal of some corneal tissue. In these situations lens exchange may be an acceptable alternative.
A General Practitioner (GP) can be a key resource in helping manage anxiety. While they may not provide specialised mental health therapy (like a psychologist or psychiatrist), they can offer several forms of support and guidance which we will delve into.
