Refractive Lens Exchange

Refractive Lens Exchange (RLE) is also known as clear lens extraction or PRELEX.

This is a way of correcting reading and distance vision and can be performed at the same time as treating your cataracts. It can correct short-sight, long-sight, astigmatism or presbyopia by replacing your lens with an artificial implant.

As a rule of thumb, your sight can be corrected successfully by Refractive Lens Exchange if you are over 40 years old and you have some early signs of cataract formation. If you are not suitable for laser eye surgery because your short or long sight is too marked you may be suitable for this treatment.

You also might wish to consider Refractive Lens Exchange if you’re finding that your use of contact lenses or glasses is getting in the way of your daily life to a great extent.

Posterior Capsule Opacification (PCO)

Sometimes a condition called posterior capsule opacification (PCO) can arise after a lens implant procedure. A cloudy layer of scar tissue can form behind your lens implant.

At Eye Wales we use Yag laser capsulotomy to treat this condition.

It is a simple procedure that is performed commonly and which is very safe.

What is Refractive Lens Exchange surgery like?

Refractive Lens Exchange surgery is painless and straightforward. Technically it is a very similar process to modern cataract surgery. There is a very low risk of complications, and it is now a very popular treatment.

During surgery your natural lens is removed and replaced with an implant made of clear plastic. You will not be aware of this implant, and it will stay in your eye permanently.

Can I have Refractive Lens Exchange in both eyes?

If you need to have surgery in both eyes, we can discuss with you at your consultation which of your eyes is best treated first.

Only one eye can be treated at a time, with an interval of around two weeks in between.
