Posted by: Missouri Eye Institute in Blog on July 7, 2025

If you’re considering vision correction, you’ve likely come across two popular options: LASIK and Refractive Lens Exchange (RLE). Both procedures offer life-changing clarity but are designed for different eyes at different stages of life. 

Understanding your refractive error, age and corneal health can help determine which path leads to your best possible vision. At Missouri Eye Institute, we’re here to guide you toward the most effective solution—whether that’s LASIK or a lens-based LASIK alternative.

The Difference Between LASIK and RLE

LASIK and RLE are both advanced eye surgeries, but they target different aspects of vision correction. LASIK involves reshaping the cornea to improve how light is focused on the retina, making it ideal for younger patients with stable prescriptions. RLE, on the other hand, replaces the eye’s natural lens with an artificial one, addressing issues like presbyopia (over-40 vision that creates the need for bifocals and reading glasses), myopia (nearsightedness) and hyperopia (farsightedness). While LASIK corrects corneal issues, RLE offers a solution for lens-related problems, often providing broader and more permanent results for older adults.

Age and Vision Goals

LASIK is typically recommended for patients between 18 and 45 who have stable prescriptions and healthy corneas. It reshapes the cornea to correct nearsightedness, farsightedness and astigmatism. RLE, on the other hand, is ideal for patients over 40 who are experiencing presbyopia or wish to prevent future cataracts. It replaces the eye’s natural lens with an artificial one, offering sharper focus and reducing the need for reading glasses. (If cataracts are already developing, your doctor may recommend multifocal cataract surgery instead, as cataract surgery becomes medically necessary once the natural lens begins to cloud.)

Refractive Error and Prescription Strength

If you have a mild to moderate refractive error, LASIK may be the most straightforward solution, as it effectively reshapes the cornea to provide clear vision. However, patients with very high prescriptions—including extreme nearsightedness or farsightedness—or those who are tired of relying on readers or bifocals, may benefit more from RLE. This procedure replaces the eye’s natural lens with an artificial, biocompatible lens, correcting refractive errors and reducing dependence on glasses. 

Corneal Thickness and Eye Health

Corneal thickness is a key factor in determining LASIK eligibility. If your corneas are too thin or irregular, LASIK may not be ideal for you. Conditions such as keratoconus, dry eye syndrome or severe astigmatism can also limit LASIK suitability. RLE, by contrast, bypasses the cornea entirely and focuses on replacing the lens inside the eye, making it a viable option for individuals with these conditions. Patients concerned about developing cataracts or other lens-related issues may find RLE to be a more comprehensive solution, as it addresses both current vision problems and future risks.

Long-Term Outcomes and Lifestyle

LASIK offers fast recovery and long-lasting results, especially for younger patients with stable vision. RLE not only corrects vision but also eliminates the risk of cataracts, since it replaces the natural lens with one that can’t cloud over. If you’re looking for a permanent solution that addresses both current and future vision needs, RLE may be the better fit.

Making the Right Choice

Choosing between LASIK and RLE isn’t just about age or prescription—it’s about your lifestyle, eye health and long-term goals. At Missouri Eye Institute, our laser eye surgeons provide personalized consultations to help you make an informed decision. Whether you’re a candidate for Springfield LASIK or exploring RLE, Missouri Eye is here to help you see the possibilities.

Frequently Asked Questions

How long does it take to recover from LASIK or RLE? 

Most patients notice improved vision within 24 hours of LASIK and return to normal activities in a day or two. Full healing may take a few weeks. After RLE, most notice clearer vision within a day or two, and eyes should fully adjust and stabilize in 4-6 weeks. 

Is RLE painful? 

RLE is performed under local anesthesia and the recovery is similar to LASIK. Patients may feel mild pressure but no sharp pain during the procedure, and healing is very quick. Missouri Eye employs the most advanced equipment and best surgical practices to ensure patient safety and a comfortable recovery.

Can I drive after laser eye surgery? 

You’ll need someone to drive you home after surgery. Most patients can resume driving within a day or two, depending on their recovery. Your surgical team will provide you with clear instructions for pre- and post-surgery care to make sure you heal quickly and comfortably.

Will I still need glasses after surgery? 

Many patients achieve 20/20 vision or better with LASIK. RLE patients can greatly reduce or eliminate the need for the inconvenient bifocals and reading glasses that may be holding them back.

How do I know if I’m a candidate for LASIK or RLE? 

A comprehensive eye exam is the best way to determine your eligibility for permanent vision correction. Your doctor will assess your prescription, eye health and lifestyle to help you determine if surgery is right for you, as well as tailor a treatment plan that helps you achieve your vision goals.
