Refractive Lens Exchange (RLE): Everything You Need to Know

Refractive Lens Exchange (RLE) is a type of eye surgery in which your natural lens is replaced with an artificial intraocular lens (IOL) to correct vision. RLE is similar to cataract surgery, but it is done to correct refractive errors such as presbyopia, high myopia and astigmatism before the onset of cataract.

The procedure of Refractive Lens Exchange includes:

1. Eye drops to numb the eye for a pain-free experience.
2. Minor surgical procedure to remove the natural lens
3. Insertion of a custom-made IOL to improve visualisation
4. Fast recovery with little downtime

A frequent inquiry patients have is, “Should I opt for RLE or LASIK?”

• If you have presbyopia, high myopia or thin corneas, opt for RLE.

• If your refractive errors are mild and you are looking for a quick recovery, then you should opt for LASIK

Another option to RLE is Wavefront LASIK, which tailors the laser corrections to the individual abnormalities of your eyes.

• Wavefront LASIK offers a more accurate reshaping of the cornea, but cannot correct presbyopia.

• RLE is a permanent solution for distance and near vision problems as it replaces the natural lens.

For people over 40 years old who require reading glasses, RLE is a more suitable option than Wavefront LASIK.

RLE and cataract surgery are very alike, as both procedures involve replacing the lens. The difference is, however, that the surgery is being done for:

• Cataract Surgery: This is a procedure that is performed when the lens becomes cloudy and interferes with vision.

• Refractive Lens Exchange: Refractive Lens Exchange is a procedure that is done before cataracts form to enhance vision.

With RLE, you avoid the development of future cataracts!

For some patients, Implantable Collamer Lens (ICL) is an option to RLE.

• If you have presbyopia or are looking for a permanent solution, opt for RLE.

• If you have high myopia, select ICL.

• Permanent Vision Correction – Glasses and contacts not required

• Prevents Cataracts – decreases future eye surgeries.

• Solves the problem of Presbyopia – Perfect for those over 40 years old

• Available Custom Lenses – Multifocal, monofocal, toric lenses available

• More Expensive than LASIK – It may not be covered by some insurance companies.

• Longer Recovery – 1-2 weeks to heal completely

• Side Effects – Glare, halos or dry eyes in some cases

Most people will have a bit of blurriness for the first several days to weeks after the Refractive Lens Exchange Procedure, but will see improvement over time.

🔹Blurry Vision Following Refractive Lens Exchange – Temporary, due to adjustment of eyes.

🔹Light Sensitivity – typically clears up within weeks.

🔹Dry eyes – very common and can be treated with lubricating drops

🔹Glare or Halos – Some patients see glare or halos at night.

RLE is generally a safe procedure, however there are some risks associated with refractive lens exchange, such as:

⚠ Infection (rare but treatable with antibiotics)

⚠ The lens is displaced (may need to be adjusted).

⚠ Retinal Detachment (in high myopia patients, it is a risk factor)

ClearView Eyes refractive surgeons reduce risk by utilizing the latest technology and tailoring treatment plans to each individual.

Most insurance companies will not pay for an elective RLE unless there is a medical reason (such as severe cataract). However, you can use:

• Health Savings Accounts (HSA) or Flexible Spending Accounts (FSA)

• ClearView Eyes has a variety of financing options available.

Refractive Lens Exchange (RLE) is an excellent choice if you:

• Want to permanently correct vision and prevent cataracts

• Be over 40 years old, have high myopia, or astigmatism

• Do not have thick enough corneas to be a candidate for LASIK
