Refractive Lens Exchange

“The utter Bliss of being able to see clearly without glasses”
“Perfect sight for the first time in my life”
Refractive Lens Exchange or Natural Lens Replacement is a process where the natural lens is replaced by an Advanced lens Implant to correct vision. This same procedure is branded by some companies and clinics as Clarivu or NuVu or PreLex. 


Refractive Lens Exchange (RLE) is the procedure of choice if you:

  • Wear reading glasses
  • Wear varifocals
  • Want a permanent cure
  • Over 50 years of age
  • Cannot / will not have laser eye surgery
  • Want a Painless 10 minute procedure with rapid return to work
We are one of the original clinics offering this revolutionary treatment for Presbyopia or age related loss of reading vision with over 18 years experience.

Viewpoint offers the full range of advanced implants to customise your treatment and to give you the vision you want.

Whether you need good close up vision for your work or
You are a racing driver and need perfect far vision or
You want both, near, far and something in between
We will find a solution to satisfy your needs.

For patients who are presbyopic (aged over 45-50 years) and/or unsuitable for other refractive procedures, refractive lens exchange with advanced lens implants is a revolutionary breakthrough.

The aim of refractive lens exchange is to reduce your refractive error (long or short sight) so that you can enjoy clearer vision without spectacles or contact lenses. The technique is similar to that used in modern cataract surgery. Your own natural lens is removed, and a lens implant is put in its place.

Lens exchange surgery offers the opportunity for you to have a lens implant which can allow you to be independent of glasses for most day to day  activities. These ‘State of the Art’ lens implants may be multifocal or accommodative lens implants which can correct presbyopia  (the need for reading glasses). Other implants, so called Toric implants can even correct astigmatism. These implants are also suitable for patients having cataract surgery who wish to be free from glasses after their operation.

“I opted for local anaesthetic and must admit nerves kicked in on the day of operation. I should not have worried. …… No pain, No long drawn out operation, No problem. My vision now feels better than with contact lenses However as explained I will need glasses for very close work. I have worn glasses since I was 11 years old. Why did I wait so long (now 56) for refractive surgery?” Jim G from Yorkshire had RLE

This short procedure takes only five to 10 minutes and is done under local anaesthetic. We use numbing eye drops not needles to completely anaesthetize then eye. The surgery is completely painless. Through a small opening (microincision) the natural lens is removed and a replacement lens is slid into its place. The recovery is almost instantaneous with most patients able to watch TV immediately upon return to their rooms.

“It all happens very quickly, perhaps 5 -10 minutes per eye and then you are back in your room. There is absolutely no pain at all as the eyes are under topical anesthetic…. I just wish I hadn’t worried so much before the operation as it was such a simple procedure. I think I worried so much because it was my eyes and they are so precious…..Mr. Chitkara came to my room about 1 hour after surgery and lifted my eye pads. I was asked if I could see anything. There was a clock on the wall and I was asked if I could tell the time. I was able to tell him that it was 11 am. I honestly could not believe that I could see so soon.” Lesley G from Isle of Man

“I was very surprised to see the television on the wall of my bedroom. I was allowed home the next day, and it was all my wife could do to prevent me from driving home. The following day, I did undertake a motorway journey with her by my side….. I lost only one day from my office.”
Michael C, Consultant Surgeon

“I can honestly say that this operation has changed my life. Prior to surgery, I had a restricted pilot’s license. A few months after the operation, the civil aviation authority, awarded me a full license without the need for me to carry spare spectacles. I am a keen amateur musician, and I can read music unaided in most lighting conditions. It is very useful appeal to read music, and watch the conductor at the same time. This is always difficult, wearing reading glasses.” Michael C, Consultant Surgeon had RLE

“I had refractive lens exchange surgery on 16 November 2007. I say that date so clearly as it is a date I shall never forget and my life was totally changed. I am still thrilled each morning when I first peep open my eyes and can SEE. No more bumbling about looking for specs to use until I got up properly and put in my contact lens. For over 37 years these contact lens had been my “eyes” and cannot tell you what a release it is not to have to deal with them or consider them. But best of all, is the fantastic vision that I now have. I am still surprised with the new intensity of colours – that was a totally unexpected bonus. My sight is superb with details apparent to me that I never noticed before. All of this was through the efforts of Mr Deepak Chitkara at Viewpoint Vision. He is totally professional but was also very good at giving me the necessary information to give me the confidence to undergo this operation. Great job, Deepak, thank you very much!” Barbara B, Wiltshire (had RLE)

Small Incision Surgery

Since Refractive Lens Exchange is small incision surgery, it offers many quality-of-life benefits to the patient:

  • Early return of good vision (within a few hours in most cases)
  • Normal or near normal vision within days of surgery
  • Large degree of long sight or short sight can be eliminated
  • Astigmatism can be addressed during the surgery
  • No postoperative padding of the eye
  • Very few restrictions after surgery – i.e., normal household, recreational, and even occupational activities may be resumed within a few days
  • Significantly reduced need for aftercare and follow-up visits compared with conventional surgery
  • Both eyes can be treated on the same occasion
  • Removal of your natural lens means you will not develop cataracts as you get older
  • Permanent solution to your focusing problem!

Intraocular Lenses

Following removal of your natural lens, an intraocular lens is placed in the same position as your natural lens. It remains there permanently. The intraocular lens offers significant advantages:

  • Magnification is at the natural level
  • Full peripheral (side to side) vision is retained
  • The lens is placed inside the eye during surgery and does not need to be adjusted

Posterior Capsule Opacification

When you have your surgery, the capsule that held your own natural lens is left in place. With time, this can thicken and become cloudy, impairing your vision. All that is required is a few seconds of YAG laser treatment in the clinic to ‘polish’ away the cloudy capsule. This usually restores clear vision within a few hours.

I had Lens Refraction Treatment on the 25.05.2016 and cannot believe the difference it has made to my vision.  I had really poor sight prior to the operation and I could only see the first large letter on the eye test chart!  I also had the beginnings of cataracts in both eyes.  I was really nervous about the operation as I have an 'eye phobia' and couldn't even manage contact lenses.  Deepak was very reassuring and the staff on the day ward at the hospital were great.  The op is very quick (10 minutes each eye) and completely painless.  I was able to drive by the afternoon of the next day and back in work on day 2 after the op, using my computer and writing reports!  I really wish I'd had the surgery earlier as I have worn glasses since I was 7 years old and I'm sixty now.  The follow up care is great too.

Having worn glasses for 25 years i was recommended Viewpoint by two work colleagues who had lens implants. As my eyes were never suitable for laser i was interested in the lens implants. I was confident with Mr Chitkara after the consultation and two weeks later i had the procedure. The follow up care from the operation was excellent by Mr Chitkara. Its great not to have to put glasses on, putting makeup on, driving, distance, reading. I highly recommend Mr Chitkara for his professionalism and care. Maureen N - Widnes
Sarah P (Urmston Manchester)   I underwent Lens Replacement Surgery under the care of Mr Chitkara In September 2014 and I am absolutely delighted with the result and the care that I received throughout the process. Everything was thoroughly explained with realistic and honest expectations. The procedure was painless, only experiencing minor discomfort in the hours following surgery requiring nothing more than simple pain relief. I work as a nurse in the NHS and was back to work and driving within two days of the procedure. I have been regularly followed up and examined following my surgery and was discharged at 6 months with 20/20 vision.   I would highly recommended this procure and the care given by Mr Chitkara and his team at Viewpoint was of the highest standard.   Thank you   Regards
