What is it
What is Lens Replacement Surgery?
Definition
Lens replacement surgery, also known as refractive lens exchange (RLE) or clear lens extraction, is a procedure that replaces the eye's natural lens with a clear artificial intraocular lens (IOL). It is designed as a permanent alternative to glasses or contact lenses, particularly for people over 50 who are developing age-related near vision loss (presbyopia) or who are not suitable for laser vision correction.
The surgery uses the same proven techniques as cataract surgery. The key difference is that the natural lens is still clear rather than cloudy. By exchanging it for a carefully chosen IOL, we can correct short-sightedness, long-sightedness, astigmatism and presbyopia in a single procedure.
When To Consider Lens Replacement
Lens replacement is often considered when glasses or contact lenses no longer meet your needs, or when you want greater independence from corrective eyewear. It can be a suitable option if you are over 50, have a high prescription, or have early lens changes that would make laser surgery less predictable. Your consultant will assess your eyes, lifestyle and visual goals to advise whether RLE, cataract surgery, or another treatment is the right path.
The Treatment
Lens Replacement Treatment
How Is It Performed?
Lens replacement is performed as a day-case outpatient procedure, usually under local anaesthetic drops. Most patients are with us for a few hours and return home the same day.
Numbing the Eye
Anaesthetic drops are applied to numb the eye. You remain awake throughout, and the procedure is typically comfortable.
Creating an Opening
A small, self-sealing incision is made to access the natural lens.
Removing the Natural Lens
The lens is gently broken up and removed using a specialised ultrasound instrument.
Inserting the New Lens
A clear intraocular lens is inserted in place of the natural lens. The type of lens is chosen in advance to match your prescription and lifestyle, whether that is a monofocal, toric, multifocal or extended-depth-of-focus option.
Preparing For Surgery
Preparation begins with a comprehensive eye examination and a discussion of the best lens options for your needs. You will receive pre-surgical instructions, including any changes to medication, and should arrange transport home on the day of surgery. Your consultant will also talk through aftercare so you know what to expect before, during and after the procedure.
Post-Surgery Care
After surgery it is important to follow your aftercare instructions closely. This includes using prescribed eye drops, wearing an eye shield at night if advised, avoiding rubbing the eye, and attending your follow-up appointments. We recommend refraining from strenuous exercise, swimming or heavy lifting for two weeks. Most patients notice a significant improvement within days to weeks, with vision continuing to settle over the following months.
Suitable Patient Candidates
Lens Replacement Candidates
Ideal conditions for the treatment
Over 50 With Presbyopia
Ideal for people who have started to lose near vision with age and want a lasting alternative to reading glasses or varifocals.
Want Greater Freedom From Glasses
Suited to those who would like to reduce or eliminate their dependence on glasses or contact lenses for daily activities.
Not Suitable for Laser Vision Correction
A strong option if a high prescription, thin corneas or early lens changes make laser surgery less appropriate.
Stable Eye Health
Candidates should have healthy eyes overall, without untreated conditions that would affect healing or the performance of the new lens.
For Patients At Our Clinic
Candidacy for lens replacement is always decided on an individual basis after a full assessment of your eyes and medical history. If you are considering RLE, please book a consultation so we can discuss your goals, lens options and any questions you may have.
Frequently asked questions
Lens replacement is performed as an outpatient procedure under local anaesthetic drops. A small incision is made, the natural lens is removed with a specialised ultrasound instrument, and a clear intraocular lens is inserted in its place. The surgery usually takes around 15 to 30 minutes per eye, and you can return home the same day.
