What is NuVu™?
NuVu™ Refractive Lens Exchange (RLE) or PRELEX is the alternative solution to laser eye surgery for those who are are over the age of 40 and want a permanent solution for vision correction. With major advances in lens technology, this procedure involves removing the natural lens of the eye and replacing it with an artificial lens to restore vision.
The artificial lens can be of the correct focusing power to correct the vision and reduce or alleviate the requirement for glasses. The procedure is more advanced form of cataract surgery as the lens inserted is more technologically superior and the results more accurate.

What are the risks and complications?
The aim of the surgery is spectacle freedom. This is obtained in the vast majority of patients. However there are some risks and these will be discussed with you in consultation and again prior to your operation.
Although refractive lens exchange is a very successful technique, it is a surgical procedure. All our surgeons are experts in intra-ocular surgery and have considerable experience with this technique.
Our team operates from state of the art hospitals where the equipment and the products used are of the highest standard. Every effort is made to minimise risk and ensure your operation is safe.
Serious problems during or after surgery are very rare; however every surgical procedure has risks and potential complications.
What types of IOLs can be used?
Monofocal lenses have a single focus that is normally set for distance vision. Used for over 50 years in eye surgery, they are an excellent and reliable method of improving the distance vision. Glasses are rarely required for distance vision, they have few unwanted side effects, but spectacles will almost certainly be needed for near and middle range vision.
Multifocal lens implants
These provide a great solution for people who prefer not to wear spectacles for most activities but who accept they may be needed for visually demanding tasks such as reading very small print or reading in dim light.
Accommodative lens implants
These lenses adapt within the eye depending on the distance viewed, reducing the need for glasses after surgery. The degree to which they adapt can vary from person to person and therefore the result can be less predictable than multifocal lenses.
Toric lens implants
These lenses are an excellent way of treating high degrees of astigmatism. “Toric’ lenses can be either monofocal or multifocal in design.
Blended or Monovision
It is possible to gain a large degree of spectacle independence by implanting a lens to correct distance vision in one eye and a lens to correct near vision in the other eye. This option is best tolerated by individuals who have previously enjoyed monovision with their contact lenses, and a trial of this situation is advised beforehand.
What to expect on admission to the clinic
Once this has all been completed, the nurse will instil the drops, which dilate your pupil in preparation for the operation. You will also have another chance to discuss the operation with your consultant surgeon. You will be asked to sign a consent form which states that you have been provided with and understand all the information given relating to the operation (including the risks and benefits of surgery) and that you agree to the proposed treatment.
The ophthalmic nurse will come to see you to explain what will happen during and after the operation, and to answer any further questions you may have.
You will be taken to the operating theatre in your own clothes, so it is important to wear something comfortable.
What to expect during surgery
Immediately after your operation
You will be given a combination antibiotic and anti-inflammatory eye drop to take home, with written instructions on how to instil these and the frequency with which they should be used. They are usually to be used four times a day for two weeks and then twice a day for two weeks. You may leave the hospital when you feel ready.
How quickly will your vision improve?
Driving and travel If you are in any doubt regarding your visual status you should refrain from driving until you have been seen for review in the clinic. It is acceptable to travel (including by air) following lens surgery. However, please remember that you will need to continue putting drops in the eye for approximately four weeks.

What shall I do with my glasses?
If you wear contact lenses the best solution is to wear the contact lens in the unoperated eye only.
A follow-up appointment in the outpatient clinic is usually arranged a week later, and the second eye operation is done two to four weeks later.
