Refractive Lens Exchange

Refractive lens exchange (RLE), also known as clear lens extraction, or CLE, is a surgical procedure for vision correction that replaces the natural lens of the eye with an intraocular lens, or IOL. Using the same surgical techniques as cataract surgery, the clear lens of the eye is removed and replaced with an IOL to change the focusing power of the eye.

An alternative to laser vision correction, RLE avoids the need for a corneal modification that is used during LASIK or SMILE, and instead uses the same procedures performed in cataract surgery.

Patients who choose to undergo refractive lens exchange have several options when it comes to the type of IOL that will be implanted into the eye. The RLE procedure uses the same IOLs used in cataract surgery and is able to treat all types of visual disorders, including myopia, hyperopia, presbyopia and astigmatism. Patients are provided with a choice of the most advanced premium IOLs which will allow them to see clearly at all distances based on their unique, individualized needs.

Who is a candidate for Refractive Lens Exchange?

Refractive lens exchange is ideal for patients who:

  • Want to reduce or eliminate their dependence on glasses or contact lenses
  • Are between the ages of 45 and 75 years of age
  • Have high myopia, high hyperopia, presbyopia or astigmatism, with or without cataracts
  • Have early symptoms of cataracts
  • Are poor candidates for SMILE, LASIK or PRK
  • Have no health issues that affect the eyes

What are the benefits of Refractive Lens Exchange?

A refractive lens exchange is an alternative to those patients with corneas that are too thin for a laser vision correction procedure. Some of the advantages of RLE include the following:

  • Increased freedom - RLE successfully treats a wide range of hyperopia and myopia to reduce dependence on glasses or contact lenses.
  • Premium intraocular lenses - The implanted lens can be customized to treat astigmatism and presbyopia to optimize vision.
    • Astigmatism - Toric intraocular lenses can be used to correct astigmatism to improve overall vision.
    • Presbyopia - Trifocal or Extended Depth of Focus intraocular lenses can be used to decrease the need for computer or reading glasses.
  • Cornea remains untouched - Patients previously not a candidate for laser vision corection due to thin corneas, may now benefit from lens-based surgeries such as RLE.
  • Cataract prevention - RLE eliminates the risk of developing cataracts in the future.
  • Long-lasting results - RLE is a permanent solution that decreases the risk of deteriorating vision due to age or regression associated with corneal surgeries. 

How is Refractive Lens Exchange performed?

The refractive lens exchange procedure is performed on an outpatient basis using the same techniques as those for cataract surgery.

A topical anesthesia is applied to the eyes to minimize discomfort during the procedure. Through a tiny incision of 3mm or less, the natural lens of the eye is removed and replaced with an IOL that is inserted through the same opening. Once inserted, the lens is unfolded and moved into its permanent position in the eye. There are no stitches needed as the incision will be able to seal on its own. The refractive lens exchange procedure takes approximately 20 minutes to perform in each eye and offers patients significant and immediate results.

What are the expectations after Refractive Lens Exchange?

After RLE, patients can return home the same day, and can return to work and other regular activities after 1-2 weeks, depending on the work environment and visual demands. Many report immediate improvements to their vision, and vision will continue to improve as the brain adapts to the new lens. RLE is typically completed without any stitches because the small incisions are designed to be self-healing. Vision will be blurred for the first few days, with gradual improvement over the first 2 weeks. It is expected to experience irritation, glare, haloes and light sensitivity during the initial healing phase. 

The extent of the results of the RLE will depend upon the patients eyes, lifestyle and the IOL selected for the procedure. Many patients are able to eliminate their dependence on glasses or contacts after this procedure!

What are the risks and complications of Refractive Lens Exchange?

All surgery carries some degree of risk. These concerns should be discussed, in detail, with your surgeon. The risks and complications of a refractive lens exchange are the same as those of cataract surgery and may include:

  • Retinal detachment
  • Increased pressure in the eye
  • Infection
  • Bleeding
  • Ptosis
  • Sensitivity to light
  • Dry eyes
  • Glaucoma
  • Distortion in vision
