A Revolutionary Reversible Trifocal Lens Exchange Procedure
Introduced to the UK by LaserVision, this new Trifocal Multifocal Lens Technology ensures the safety of complete lifelong reversibility to a monofocal lens should the health of the eye change.
Two Premium optic lenses in one eye.
Achieving perfect visual results for our patients is paramount. Even with the best patient selection and most accurate work, results can change.
As a living tissue, the health of the eye can deteriorate as we grow older. And as no one can predict the future, having the life-long ability to reverse the multifocal lens technology should it become unsuitable brings unparalleled safety to lens exchange surgery.
Introducing the Sulcoflex Duet Lens Exchange procedure.
Performed by LaserVision for the first time time in the UK, the DUET procedure involves the simultaneous or sequential implantation of a primary capsular bag IOL and a supplementary Trifocal sulcus IOL. This is performed as a planned DUET procedure during the initial surgery.
The Sulcoflex DUET Lens Exchange Technique adds little time to the overall surgical time, and yet offers an elegant adjustable solution.
What happens during the procedure?
The DUET procedure is centred on an established technique called piggyback lenses. Patients undergo routine surgery but at the end a second lens with unique trifocal technology is implanted in a space just in front of the new permanent lens.
The DUET lens have been specifically designed for sulcus implantation. The special design of the lens optic and haptics underlies this unique concept.

Any patient deemed suitable for a traditional lens exchange procedure should be suitable for this latest technique.
However, there are several groups of patients who may be unsuitable for a traditional capsular bag multifocal lens.Through the option of reversibility, the Sulcoflex Duet Lens Exchange procedure may offer a solution for these patients.
Finally, it offers patients who have undergone traditional surgery with an older lens technology the option to upgrade their lens to the latest technology for spectacle independence.
Exploiting the benefits of reversibility and adjustability
The Sulcoflex DUET Lens Exchange Procedure is an adjustable option which allows you to treat an even wider range of patients to meet both their visual and lifestyle needs. Unlike traditional multifocal IOLs or refractive laser treatments, the DUET Lens procedure is easily reversed.
Refractive change or surprise cannot be predicted, and nor can a failure to neuro-adapt. Through the DUET procedure, the optic system can be easily adjusted or converted back to monofocality in a straightforward procedure.
The DUET procedure empowers patients with the assurance that the procedure is reversible back to a monofocal lens.
More Information about Sulcoflex Duet Lens Exchange
For more information regarding this treatment as well as any frequently asked questions, please see below.
The Sulcoflex Duet Lens Exchange procedure is an evolution of standard Refractive Lens Exchange surgery. With major advances in lens technology, this procedure involves removing the natural lens of the eye and replacing it with two artificial lens to restore vision for all distances.
The first artificial lens is a distance lens and is placed within the natural capsule that holds the original lens. This lens is a permanent lens.
The second lens is a trifocal lens that restores vision at intermediate and near distances. This lens is positioned in the space just in front of the first lens.
The procedure is a routine procedure which takes between 5 and 10 minutes to perform. At LaserVision, we normally perform this surgery whilst you are awake. The anaesthesia required is only eye drops though you may be given a mild sedative if you are anxious. A small proportion of patients prefer to be fully asleep during surgery, and with the back up of full hospital facilities, we are able to offer general anaesthesia. Surgery is performed on an day care basis.
During the procedure the natural lens is gently removed and a new permanent, artificial lens is inserted to replace the natural lens. The lens chosen is specific to meet your requirements after surgery.
There are several advantages to the DUET Lens Exchange:
- It is a permanent vision correction solution
- The trifocal lens technology remains fully reversible should the health of the patient or the eye change with time
- The procedure improves the perception of colours and contrast sensitivity
- It results in clearer unaided vision
- Prevents cataract formation and can be performed to clear cataract already present
- Fast recovery with almost immediate improvement
- The procedure is painless
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.
These will be discussed in detail with you during your consultation.
You will be shown to your private room. A nurse will perform some routine investigations including checking your pulse and blood pressure. The nurse will also record details of any medications you are taking and ask questions about your general health.
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.
During the surgery, you will be lying down and a theatre assistant will hold your hand at all times for comfort and reassurance. The procedure takes between 5 and 15 minutes and during this time, you will see some lights and feel some water. The procedure is painless.
After the operation you will be taken to the recovery room, and then back to your private room. Whilst resting after the operation you will be offered refreshments.
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.
Your vision will improve almost immediately. The vision will continue to improve until your pupil returns to its normal size. Thereafter the operated eye can take time to settle but you should start to notice an improvement in your vision within a couple of days.
It is not advisable to drive until you feel confident to do so. Your ability to drive may be dependent upon a number of factors, including the vision in your other eye and the quality of your vision when using both eyes together. This will be discussed with you prior to discharge from hospital.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.
After the first operation, many people find they can go without glasses and use the operated eye; others will use their glasses and use the unoperated eye. Sometimes, if the lens is removed from the operated side of the pair of spectacles this will help. However if the prescription is strong this may not be comfortable due to the imbalance between the two eyes.
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.
LaserVision was initially founded in Guildford, Surrey. Now with clinics in over 6 locations, we are able to treat the eye conditions of patients nationwide. This treatment is available at:
