You squint at your morning coffee mug, reach across the table for your glasses, and realize you’re still half‐asleep—again. If blurry vision or glasses‐fogged lenses feel like a daily battle, you’re far from alone. Millions worldwide live with nearsightedness, farsightedness, or lens changes that make simple tasks a struggle. Thankfully, advancements in eye surgery mean you don’t have to settle for imperfect vision forever. Two of the most popular solutions are LASIK vs RLE—each reshaping or replacing parts of your eye to restore clear focus. But how do you know which path is right for you? In this guide, we’ll explore the key differences between LASIK and refractive lens exchange, helping you decide which vision‐correction surgery aligns best with your lifestyle and eye health.
What Is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) is one of North America’s most frequently performed elective procedures. The procedure uses a laser to reshape the cornea to correct common refractive errors, including nearsightedness, farsightedness, and astigmatism. Successful LASIK surgery reduces, and sometimes eliminates, the need for glasses and contact lenses.
LASIK is usually considered an elective surgery and may not be covered by insurance, although it’s still worth asking your insurance company about advanced vision correction options.
What Is Refractive Lens Exchange(RLE)?
Older adults, especially those who have never worn glasses, may think LASIK is their only solution as they begin to age and need reading glasses. However, due to the number of disqualifying factors, many people 40 and older may not be good candidates for LASIK.
Refractive lens exchange (RLE) replaces the natural lens of the eye with an artificial intraocular lens (IOL). This procedure is typically reserved for patients who experience a change in their vision due to the eye’s natural aging.
Lens replacement surgery is identical to cataract surgery; the difference is that RLE replaces a clear lens rather than a lens that has become cloudy due to a cataract. As in cataract surgery, the types of artificial lenses available with lens replacement surgery are the same and depend on the health of your eyes.
Refractive Lens Exchange vs LASIK
If you’re considering eye surgery to improve your vision, talk to an eye doctor to learn about your options, which may include options in addition to LASIK and RLE. The best way to decide whether LASIK or lens replacement surgery is right for you is to consult an eye doctor. Here is a quick side-by-side comparison of LASIK and RLE to give you a general idea of the differences between these two vision correction surgeries.
