Tailored lens replacement plan designed around your eyes, prescription and visual goals.
Lens replacement surgery is a vision correction procedure that replaces the natural lens of the eye with an artificial lens, helping to provide clearer vision and reduce your reliance on glasses or contact lenses.
At Optegra, treatment is carried out by experienced Consultant Ophthalmic Surgeons, with a choice of advanced lens options selected to suit your prescription and visual needs.
From your initial consultation through to treatment and aftercare, you’ll receive specialist care and guidance from our team at every stage.
Lens Replacement Surgery at a glance:
Lens replacement surgery, also known as Refractive Lens Exchange (RLE), involves removing your eye’s natural lens and replacing it with a clear, artificial intraocular lens (IOL). The replacement lens is carefully selected based on your prescription, eye health and visual needs.
The surgical technique used for RLE is the same as that used in modern cataract surgery. However, the purpose of each procedure is different. Cataract surgery is carried out when the natural lens has become cloudy and is affecting vision. RLE, on the other hand, is an elective treatment for patients whose lenses are still clear, but who want a long-term solution to age-related vision changes or a greater level of independence from glasses.
At Optegra, your consultant will carefully assess your eyes and discuss whether lens replacement surgery is the right option for your lifestyle and visual goals.
Well you are a bit trepidatious with someone touching your eyes, but the team reassured me so much, and it was very quick – only around 20 minutes for both eyes – and completely painless. It could not have been easier to be honest, it was completely fine. […] Now I can look forward to life being easier. No glasses frame blocking my peripheral vision when driving, no forgetting my specs when I leave the house and everything being a blur, no glasses falling off when I play with my kids – this is liberating!
Your suitability for lens replacement surgery will be carefully assessed during a detailed consultation. Your consultant will consider your age, overall eye health and personal vision goals before recommending the most appropriate treatment.
Lens replacement surgery may be suitable for patients who are not suitable for laser eye surgery, such as those with higher prescriptions or thinner corneas. It is designed to treat a range of common vision concerns, including:
As the natural lens is replaced during the procedure, patients who undergo lens replacement surgery will not go on to develop cataracts in the future. This removes the need for cataract surgery later in life.
Your consultant will talk through all of these factors with you to ensure lens replacement surgery is the right choice for your eyes and your lifestyle.
Lens replacement surgery is performed as a day-case procedure, so you can return home shortly after your treatment. Where suitable, both eyes can be treated on the same day, allowing for a quicker overall recovery and faster visual improvement. In some cases, your consultant may recommend treating each eye separately, depending on your individual needs.
On the day of surgery, anaesthetic eye drops are used to ensure the procedure is comfortable. If required a mild sedative can also be offered to help you feel relaxed. Your consultant will make a very small incision in the surface of the eye to access the natural lens. The lens is gently emulsified using advanced ultrasound technology and carefully removed before being replaced with a clear artificial intraocular lens.
Optegra offers a range of advanced lens options, including multifocal intraocular lens designs that are intended to improve vision at near, intermediate and distance ranges. Your consultant will guide you through the most suitable option to help you achieve clearer vision and greater independence from glasses or contact lenses.

| Lens Type | What will my vision be like? | Convenient for… | Will I still need glasses? |

Recovery from lens replacement surgery is usually quick, with many patients noticing clearer vision within 24 to 48 hours. It is normal to experience some temporary blurring, light sensitivity or mild discomfort in the first few days as the eye begins to heal. You will be given eye drops to support recovery and reduce the risk of infection.
Most people feel ready to return to work after around three days, depending on their role. Your consultant will advise you when returning to work is appropriate for you. You can resume driving after surgery once your consultant confirms that your vision meets the legal standard at your follow-up appointment.
To support smooth healing, it is important to avoid rubbing your eyes, swimming, dusty environments, or strenuous exercise in the early weeks. Optegra provides comprehensive aftercare for up to one year, including follow-up appointments and access to a 24-hour helpline, so you feel fully supported throughout your patient journey.
Lens replacement surgery at Optegra starts from £3,495 per eye, with clear pricing and no hidden costs.

Yes. Lens replacement, also known as Refractive Lens Exchange, is a well-established and highly effective procedure with an excellent safety record. At Optegra, treatment is carried out by NHS-trained Consultant Ophthalmic Surgeons in specialist eye hospitals, using advanced diagnostic and surgical technology.
As with any surgical procedure, there are potential risks, but serious complications are uncommon and are usually manageable if they arise. At Optegra, 99.1% of procedures are completed with no operative complications, reflecting our commitment to safety, expertise and high clinical standards.
No. Lens Replacement Surgery and laser eye surgery are different vision correction procedures. While both aim to improve your sight, they work on different parts of the eye.
Your consultant will assess your eye health, prescription and long-term visual needs to recommend the most suitable option for you.
Yes, but it may restrict the range of lenses available to you. Your Consultant Ophthalmic Surgeon will discuss all your options at a free consultation.
Yes. Lens replacement surgery, also known as Refractive Lens Exchange, uses the same surgical technique as modern cataract surgery. If you already have a cataract, or are in the early stages of developing one, the cloudy lens is removed and replaced with a clear artificial lens during the procedure.
An important benefit of lens replacement surgery is that once your natural lens has been replaced with a synthetic implant, you will not develop cataracts in the future. This means you will not require cataract surgery later in life.
Your consultant will explain how this applies to your individual eye health and long-term vision needs.
Lens replacement surgery is not painful. Anaesthetic eye drops are used to numb the eye before treatment, and a mild sedative can be offered if needed to help you relax. You may be aware of some pressure or movement during the procedure, and mild discomfort or sensitivity can occur as your eyes recover, but this usually settles within the first few days.
Lens replacement surgery is designed to provide a long-term, permanent correction to vision. The artificial intraocular lens placed in your eye is designed to remain there for life and does not develop cataracts. However, other parts of your eyes can continue to change with age, so your vision and eye health should still be monitored with regular eye examinations.
Yes, both eyes can be treated on the same day where clinically appropriate. Your consultant will assess your individual eye health and circumstances before recommending whether same-day treatment or treating each eye separately is the most suitable approach for you.
Lens replacement surgery has a high success rate, with 91% of Optegra patients achieving 20/20 vision or better. Optegra has performed more than 50,000 lens replacement procedures, with 96% patient satisfaction and 98% of patients saying they would recommend Optegra.
Individual results can vary depending on factors such as your prescription, eye health and the type of lens selected. Your consultant will assess your eyes and discuss the results you can realistically expect before treatment.
