Vision Correction
Refractive lens exchange (RLE)
In short
Refractive lens exchange (RLE) swaps the eye's natural lens for an artificial lens implant before a cataract forms. It is performed much like cataract surgery and is often considered by adults over 40 with presbyopia or high farsightedness who are not ideal LASIK candidates.
- Who it's for
- Adults, usually over 40, who want less dependence on glasses or contacts
- Procedure
- Outpatient; one eye at a time
- Insurance
- Usually considered elective and not covered
- Offered at
- Falls Church · Fairfax · Alexandria
How does refractive lens exchange work?
The surgeon removes your clear natural lens through a tiny incision and replaces it with an intraocular lens selected to correct your prescription. Because the natural lens is removed, you will never develop a cataract in that eye.
Who may be a good candidate for RLE?
- Adults with presbyopia who struggle with reading vision
- People with high farsightedness
- People who are not good candidates for LASIK or PRK (for example, because of thin corneas)
- Anyone hoping to reduce long-term reliance on glasses or contact lenses
What lens options are available?
- Multifocal implants — designed to give both reading and distance vision
- Extended depth-of-focus (EDOF) implants — a continuous range from far to arm's length
- Toric implants — built-in astigmatism correction
How is RLE different from LASIK?
LASIK reshapes the cornea and leaves the natural lens in place. RLE replaces the lens itself, which can treat presbyopia and higher prescriptions that LASIK cannot, and it prevents future cataracts. Because RLE is intraocular surgery, your surgeon will review its specific risks with you.
Frequently asked questions
Is refractive lens exchange permanent?
Yes. The lens implant is designed to last a lifetime and does not need to be replaced. Your eyes can still develop other age-related conditions, so regular eye exams remain important.
Is RLE covered by insurance?
Because RLE is usually done to reduce dependence on glasses rather than to treat a disease, insurance typically does not cover it. We will give you a clear cost estimate at your consultation.
What is the recovery time after RLE?
Many patients notice clearer vision within a few days and return to most routine activities within about a week, following their surgeon's instructions. Full stabilization can take several weeks.
Can I have RLE if I have astigmatism?
Often, yes. Toric lens implants can correct astigmatism at the same time as your prescription.
