Are You A Good Candidate For Clear Lens Extraction?



Are you not interested in laser surgery, or don’t qualify?

That’s all well and good, but if you’re still squinting to see better, there has to be another option. Taking good care of your eyes isn’t always enough.

Consider refractive procedures to help correct the problem.

Clear lens extraction (CLE) or refractive lens exchange (RLE) means replacing the natural lens in your eye with a synthetic one. Find out below if this is a good fit for you.

The History of Clear Lens Extraction

The idea of correcting refraction isn’t new. Scientists worked with it as early as the late 1800s. Take a look.

  • 1896 Lendeer Jans Lans writes a book about refractive surgery theory, suggesting cutting the cornea several times
  • 1930 Tsutomu Satu tries refractive surgery for the first time on pilots, with methods that degenerate patients’ corneas
  • 1960 Theodore Maiman invents the first laser
  • 1963 Jose Ignacio Barraquer Moner tries removing, freezing, reshaping, and replacing a layer of the cornea
  • 1974 Svyatoslav Nikolayevich Fyodorov uses a diamond knife to cut and reshape the cornea, with success
  • 1980 Rangaswamy Srinivasan uses an excimer laser (for cutting microchips) on the eye
  • 1983 Stephen Trokel does the first excimer laser surgery without removing corneal layers
  • 1986 Casimir A. Swinger finds a way to reshape the corneal layer without freezing
  • 1989 US Patent Office issues first patent for LASIK, followed by two more in 1991 and 1993

All this research into keratomileusis (reshaping the cornea) brought all kinds of procedures like PRK and LASIK. Today, there are many laser eye surgeries, but CLE might work for you if you don’t qualify for the others.

Who Is A Good Candidate?

Myopia is nearsightedness, meaning you can only see things that are close up. Most people have this condition because of a genetic predisposition. But you can also get it when your cornea or lens is too thick, or your axial length is longer than the focal point.

You might have myopia for one, several, or all the above reasons. No matter the reason, your level of myopia determines your candidacy for clear lens extraction.

Patients between 40 and 60 years old with extreme myopia will have the most success from this procedure. Extreme means greater than eight diopters, represented by D on your prescription. You also can’t have any cataracts but must have a totally healthy refractive lens.

Your doctor should spend time with you and get to know your lifestyle. There are different lens options to replace your eye’s natural lens. Without knowing what types of activities are more important to you, the doctor can’t make the best recommendation.

As with laser surgery, your vision might not be perfect after the procedure. You’ll see big improvements, but it’s not a 100% guarantee of perfection.

If you don’t have extreme myopia, you still have options. For mild myopia, try Ortho-k instead. It’s another alternative to laser surgery, and it’s a better alternative for less severe cases.

The Best Way to Correct Your Vision

If your myopia is extreme and you have healthy natural lenses, then you might think clear lens extraction sounds like a good option for you. The pioneers in refractive procedure research hoped for a solution to improve your quality of life.
