What is RLE vision correction?

If you're over 45 and starting to struggle with reading glasses—or if you’ve been told you’re not suitable for laser surgery—you may have come across the term RLE.

But what exactly is RLE, and how does it work?

Here’s a simple guide to Refractive Lens Exchange (RLE) vision correction and how Professor Paul Ursell, a specialist in lens and cataract replacement, helps patients enjoy long-lasting clear vision.

What is RLE?

RLE stands for Refractive Lens Exchange. It’s a procedure that removes your eye’s natural lens and replaces it with a clear artificial one.

It’s essentially the same as modern cataract surgery—but performed before a cataract forms, often to treat:

Presbyopia (age-related near vision loss)
Long-sightedness
Astigmatism
Patients who want vision correction but aren’t suitable for laser.

Why choose RLE?

After age 45, your natural lens begins to stiffen. That’s what makes reading difficult without glasses. Laser surgery can fix your distance vision, but it can’t restore your close-up focus.

RLE solves the root of the problem by replacing the ageing lens entirely.

With RLE, you can:

See clearly at near, intermediate, and distance
Reduce or eliminate your need for glasses
Avoid future cataract surgery.

Who is RLE for?

You may be a good candidate for RLE if you:

Are over 45
Want to reduce or eliminate glasses for all distances
Have been told you’re unsuitable for LASIK or other laser options
Want a long-term solution with lasting results.

Professor Paul Ursell specialises in helping people just like you achieve these goals safely and effectively.

What kind of lenses are used?

RLE uses intraocular lenses (IOLs). These come in a variety of types, including:

Monofocal – correct one distance (usually distance), may need reading glasses
Multifocal – offer near and distance focus
Extended depth of focus (EDOF) – a smooth range of vision, especially for intermediate and distance
Toric – correct astigmatism.

Professor Ursell will help you choose the lens that best matches your lifestyle and vision priorities.

What happens during the procedure?

You’ll be awake but comfortable (local anaesthetic)
The natural lens is gently removed through a tiny incision
The new lens is inserted into place
No stitches are needed
The procedure takes around 10 minutes.

Most people return to daily activities within 24–48 hours.

Is RLE safe?

Yes—RLE uses the same safe, proven techniques as modern cataract surgery.
It’s one of the most commonly performed procedures in the world.

Professor Ursell is a highly experienced surgeon who has performed thousands of lens replacements with excellent outcomes.

What are the benefits?

Long-lasting clear vision
No need for cataract surgery later
Reduced or no need for glasses
Personalised lens options
Quick recovery.

Are there risks?

As with all procedures, there are small risks—including infection, inflammation, or visual disturbances like glare or halos (especially with some lens types). These risks are low and are discussed fully at your consultation.

What’s the difference between RLE and cataract surgery?

They are almost identical in technique. The key difference? RLE is performed before your lens becomes cloudy, so you don’t wait until cataracts form to enjoy better vision.
