Refractive Lens Exchange (RLE): Is a surgical procedure in which the eye's natural lens is removed and replaced with an artificial intraocular lens (IOL) to correct refractive errors such as nearsightedness, farsightedness, and presbyopia (age-related loss of near vision).
How it works: RLE is very similar to cataract surgery. The key difference is that with RLE, the natural lens being replaced is still relatively clear (not completely clouded by a cataract). The goal is to eliminate the need for glasses or contact lenses by using a custom IOL to adjust the eye’s focusing power.
Who is a Good Candidate: RLE is typically recommended for:
Benefits of RLE
Considerations and Risks
Feature | Refractive Lens Exchange (RLE) | EVO ICL | LASIK |
---|---|---|---|
Age Range | Typically 45+ | 21–45 (ideal for those with stable vision) | 18–40 (depends on stable prescription) |
Vision Conditions Treated | Myopia, hyperopia, presbyopia, astigmatism | Moderate to high myopia, astigmatism | Mild to moderate myopia, hyperopia, astigmatism |
Procedure Type | Replaces natural lens | Adds a lens (natural lens stays) | Reshapes cornea |
Corneal Tissue Removed? | No | No | Yes |
Reversible? | No (permanent lens replacement) | Yes (lens can be removed) | No |
Corrects Presbyopia? | Yes | No (though monovision may help) | Partially (via monovision LASIK) |
Cataract Prevention | Yes (lens won’t cloud later) | No | No |
Recovery Time | Few days to 1–2 weeks | 1–2 days for most | 1–2 days for most |
Long-Term Stability | Very stable | Very stable | Stable, though vision may shift with age |
Ideal for Thin Corneas? | Yes | Yes | No (may disqualify patient) |
