Discover Which Vision Correction Procedure is Right for You

If you’re over 45 and starting to rely more on reading glasses, or you’ve heard the term “cataract” come up at your eye exam, you may be wondering: What’s the difference between Custom Lens Replacement (CLR) and cataract surgery?

The two procedures sound similar—and technically, they are. But understanding their differences could change how you think about your future vision.

What Is Custom Lens Replacement (CLR)?

Custom Lens Replacement is an advanced, elective vision correction procedure that replaces your natural lens with a premium intraocular lens (IOL) designed to reduce or eliminate your dependence on glasses or contacts. Unlike cataract surgery, which is performed due to a medical necessity, CLR is about optimizing your vision now and preventing future cataracts.

Key Benefits of CLR:

  • Elective procedure designed to restore youthful vision
  • No need to wait for cataracts to develop
  • Uses advanced IOLs to correct refractive errors like astigmatism
  • Often eliminates the need for glasses—for distance, near, and everything in between

“Custom lens replacement is lens replacement in the highest order in terms of technique and technology,” says Dr. Joe Ling. “It’s designed to allow for a very quick recovery and excellent outcomes so that patients can experience daily life without having to depend on glasses.”

What Is Cataract Surgery?

Cataract surgery is a medically necessary procedure performed when the eye’s natural lens becomes significantly clouded, impairing daily function. It’s often associated with older adults who begin to struggle with driving, reading, or recognizing faces due to poor visual clarity.

What to Expect:

  • Covered by insurance or Medicare
  • Basic lenses used unless patient upgrades to premium options
  • Performed one eye at a time
  • Most patients still require glasses afterward

“This is a procedure your grandparents probably had,” explains Dr. Ling. “The goal is to remove the cloudy lens and replace it with a basic implant, but not necessarily to free you from glasses.”

CLR vs Cataract Surgery: The Key Differences

Why More People Are Choosing CLR

As we age, the lens in our eyes naturally hardens and yellows, causing presbyopia and diminished clarity—even before full cataracts form. CLR lets patients take control of this aging process by acting before cataracts become debilitating.

“You don’t need to have a cataract to qualify,” says Dr. Ling. “Many of our patients are still in the early stages of lens aging and want to stay ahead of it.”

This proactive approach not only prevents cataracts from developing but often results in life-changing freedom from glasses.
