Refractive Lens Exchange vs. Cataract Surgery: What’s the Difference for Mountain View Patients?

If you’re researching vision correction options and live in the Mountain View or greater Bay Area, you may have come across two similar-sounding procedures: Refractive Lens Exchange (RLE) and Cataract Surgery. While both involve replacing the eye’s natural lens with an intraocular lens (IOL), they serve different purposes – and choosing the right option depends on your age, vision goals, and eye health.

At Peninsula Laser Eye Medical Group, we help patients across Mountain View, Sunnyvale, Palo Alto, Los Altos, and beyond make informed decisions about their vision. Here’s what you need to know.

What Is Refractive Lens Exchange (RLE)?

RLE is often recommended for patients over 40–45 who are frustrated by presbyopia (the need for reading glasses), high farsightedness, or who are no longer good candidates for LASIK or PRK. It involves replacing the eye’s natural lens with a premium IOL – often a multifocal, extended depth of focus, or toric lens—designed to reduce or eliminate the need for glasses.

Ideal for: Patients without cataracts who want long-term vision correction
Bonus: RLE prevents cataracts from developing in the future

What Is Cataract Surgery?

Cataract surgery is medically necessary when the eye’s natural lens becomes clouded, usually due to age. Like RLE, the cloudy lens is replaced with a clear IOL—but the goal is to restore lost vision, not necessarily to correct refractive errors like presbyopia or astigmatism (though that’s possible with premium lens options).

Ideal for: Patients with cloudy vision caused by cataracts
Covered by insurance: Cataract surgery is often covered, while RLE is elective
