Natural Lens Replacement Surgery in London

If you need to use glasses to be able to see things closer in detail when reading or would like to be able to see in the distance, then it is not possible to correct both of those issues with the help of a laser eye surgery. Hence, the lens replacement surgery would be a suitable option in this case. It also has added benefit that by performing this method, you will not develop cataracts in the future.

Natural Lens Replacement (NLR) is also called Replacement Lens Enhancement (RLE), Clear Lens Exchange, presbyopic lens replacement surgery and Refractive surgery. It involves the removal of the natural crystalline lens of your eye and then replacing it with an artificial intraocular lens (IOL) for vision correction.

The procedure is quite similar to cataract surgery, which is one of the most commonly performed medical procedures in the world. According to the World Health Organisation (WHO), it is one of the safest ways to correct your eyesight. However, rather than removing a cloudy lens or cataract, a clear lens is removed and then exchanged using an IOL that corrects the prescription. So, the procedure has been termed as Clear Lens Replacement.

The treatment provides the complete correction for all fields of vision as well as it ensures that cataracts will not develop in future. This means that you will be able to enjoy glasses-free vision for the rest of your life. This is one of the most commonly performed procedures in the world with more than 300,000 of which being in the UK each year.

Suitability for Lens Replacement Surgery

When we grow old, the natural lens in our eye gradually weakens thus, leading to some kind of difficulty when focusing on close objects. We also face problems at the time of reading that arises the need for wearing reading glasses after 40. This is known as presbyopia and everyone develops it at some point in time. Hence, this surgery is suitable for patients who are above 40 and face problems at the time of reading.

To qualify for the surgery, you:

  • Must be over 40 years old.
  • Should have developed presbyopia or a reading prescription.
  • Can have any prescription range.
  • Should have reletively healthy eyes (must not have a significant eye disease like glaucoma)
  • Have no existing eye infections.
  • Should not be allergic to the anaesthetic.
  • Should be in a good health.

The process involves the removal of the natural crystalline lens and then replacing them with an intraocular lens (IOL) implant to improve the eyesight. There are different kinds of intraocular lenses available which your surgeon choose accordingly to your eyes conditions and visual requirements.

When you reach the clinic on the day of surgery, our friendly team will guide you at every step of the procedure. The treatment takes less than 20 minutes for each eye and each of them will be treated separately, one after the other.

  • Anaesthetic drops will be used to numb the eye
  • A sedative is provided and dilated with drops
  • An eyelid guard is needed to avoid blinking
  • A micro-incision is usually made at the edge of the cornea
  • The phacoemulsification probe is used to break up and remove the natural lens
  • The intraocular lens is placed in the capsule where the natural lens was
  • Stitches are not needed due to micro-incision being self-sealing
  • Our specialist will go through the medications and precautions needed for recovery
  • The aftercare will begin on the next day which is followed by a check-up for your treated eye

Lens Replacement Surgery We Offer 

Intraocular lens (IOL) implants

The NHS provide the basic kind of intraocular lens (IOL) implants: Monofocal lenses that can correct distant vision only. At Optimal Vision, our surgeons provide customised treatments that are best suited for your need. The type of lens you are suited for depends on your visual needs and lifestyle. This can be determined by our eye surgeon after a comprehensive consultation at the clinic.

When multifocal IOLs were introduced, they were used for improving your near and distance vision. However, our busy work schedule in the present world has continually demanded better intermediate vision correction. So, intermediate vision correction is even more crucial than near vision when using computers, smartphones, tablets and so on. Trifocal IOLs are considered to be the latest generation of multifocal IOLs that help to improve the eyesight across all spectrums. This is associated with correcting all fields of vision; near, intermediate and distance thus, allowing patients to be glasses-free.

Trifocal IOLs do not work like multifocal contact lenses or varifocal glasses and adaptation is much more convenient and occurs naturally. These trifocal IOLs provide better vision due to transmittance of light through the extremely efficient lens implant. This can enhance your intermediate vision correction with halos and minimal glare at night time. The more satisfied the patients are with our services, the better quality of vision we can offer them more freedom from contact lenses and glasses.

Our eye surgeons use revolutionary Trifocal lenses and can treat all patients despite their age and problem. Lens Replacement helps in vision correction and ensures that cataracts do not develop in future.

Types of IOL implants

We provide different types of IOLs that provide clear eyesight at different distances:

  • Monofocal – This is a single focus intraocular lens (IOL) that can be found in both spherical and toric (for astigmatism) designs. It provides clear distance vision and glasses are required when you read and work on the computer.
  • Trifocal The lenses can help to correct more than one field with layered concentric circles. They are available in both spherical and toric (for astigmatism) designs that allow for simultaneous correction of near, intermediate and distance vision that leave patients completely glasses-free.

Our lenses at Optimal Vision

At Optimal Vision, our renowned surgeons enable you to choose the perfect lenses that will fit your visual needs.  The surgeon will correct your vision by offering complete freedom from glasses and contact lenses. We have complete access to these four commonly used Trifocal IOLs (Intra Ocular Lenses)

  • Vivity (Alcon, Fort Worth, Texas, USA) - These can be found in toric and spherical designs.
  • RayOne (Rayner, Worthing, West Sussex, UK) - These can be found in both toric and spherical designs.
  • FineVision (Phys IOL, Liege, Belgium) - They are usually available in spherical and toric designs.
  • PanOptix (Alcon, Fort Worth, Texas, USA) – You can get them in spherical as well as toric designs.

The Verion Image Guided System

This can be used for capturing a digital reference image of the eye at the time of initial assessment and thus, create a surgical plan. The equipment is used throughout the procedure that enables eye care surgeon to see all alignments and incisions. We will also help to improve accuracy and lessen errors particularly at the time of correcting astigmatism.

The CenturianVision System

Optimal Vision is among the leading clinics in the UK that uses this newest phacoemulsification system to break up and removal of the natural lens. It enables smaller incisions and can optimise every phase of lens removal. The device also helps control intra-ocular pressure throughout the treatment procedure and improves the patient’s outcome thus, speeding up the recovery procedure.

The Lux or Ophthalmic Microscope

The Lux-OR LX3 with Q-VUE Ophthalmic Microscope has been designed to offer quality visualisation throughout the surgical procedure. The microscope can expand the visual field by a highly stable, 6x greater red reflex zone for providing outstanding visual detail with top visualisation of the retina.

The lens replacement treatment is quite identical to cataract surgery. The only difference is that a clear lens can be removed in this treatment and a cloudy lens is removed at the time of cataract surgery.

The traditional intra-ocular implants are Monofocal lenses that focus light to one point only. This means that they will help to correct the vision only and glasses will be required for near vision. This kind of lens is typically used by the NHS.

A Trifocal intraocular lens with more than one focus point allows for clear distance, near and intermediate vision. It has revolutionised the results of the treatment and enables patients to be glasses-free.

The optical design of intraocular lenses is completely different from that of varifocal spectacles. Rather than a patient to move their head and adjust the focus, they can see from the distance, near and intermediate comfortably without any movements. Layered concentric circles can be used for correcting each prescription issue thus, enabling for simultaneous correction of all vision fields.

We provide lenses from the following companies:

  • Zeiss
  • Alcon
  • Rayner
  • Fine Vision – Phys IOL

The suitability for the type of lens and the treatment can be determined at your initial consultation. If you are not a suitable candidate for Trifocal intraocular lenses, then Monofocal lenses will be available. These are used to either aim for monovision or correct your distance vision in both eyes. So, you will have to wear glasses for near vision. This can be explained in further details during the consultation.

After the natural lens gets removed and replaced with lens implants, patients will probably never have to undergo any surgery again. The materials with which lenses are made have been subjected to accelerated ageing tests. However, the results have demonstrated that the lens material can last for more than 150 years before showing any signs of degradation.

There will be no pain as anaesthetic drops can be used to numb the eye. However, some discomfort can be felt while performing the treatment.

Most patients usually notice a difference to their eyesight immediately after the treatment. Distance vision is the first field of vision to settle that usually require 24 to 48 hours. However, it may require slightly more time to adjust to the new reading vision.

Generally, you require 3 to 5 days off work for office related work. The two will be for the treatment and one or two days afterwards for taking rest. Patients can carry on their daily tasks just one day after the surgery without any difficulty. Your working environment will be taken into consideration and our surgeon will advise you on the necessary precautions to take at the consultation.

There will be a few restrictions after the treatment is done. Some examples are – avoiding sports that can cause trauma to the eye, lifting heavy weights and preventing dusty environments. During your initial consultation, we will consider your hobbies and lifestyle and then advise you accordingly.

We can treat both eyes on the same day. If the risk is low and the surgeon is confident that there is a little to no risk of infection then he may opt to treat both on the same day. Occasionally to reduce the risk, it is advised to treat each eye on a separate day.

All our treatments are performed at our eye clinic in London where we offer you everything, starting from initial consultation to surgery and aftercare to be conducted in the same area.

The refractive lens exchange procedure consists of removing the natural lens where a cataract would have been developed. When a patient performs lens replacement treatment, this means they won’t develop a cataract in either eye at any point in the future.

Posterior capsular opacification (PCO) usually take place after the lens replacement. Sometimes you may develop a thickening of the posterior) of the lens capsule that holds the artificial lens in place. The thickening of the capsule may cause your eye-sight to become cloudy; however, it can be treated safely with a YAG laser procedure.

The lens implant is inside the eye where there is no sensation or nerves and so, it cannot be felt. It will not feel like a contact lens and you will not know that it is there, other than being able to experience a greatly improved vision.

Your initial consultation, treatment, one-day post-op, two weeks and six weeks aftercare appointments are performed at our clinic. Once it is done, we may ask you to visit our eye care specialists and stay closer to them for further follow-up appointments.
