Refractive surgery (including 

At Schwartz Laser Eye Center, with locations in Scottsdale, Glendale, and Mesa, AZ, our ophthalmologists and optometrists perform comprehensive evaluations to determine whether vision stability has been achieved before scheduling surgical correction.

What Stable Vision Means

Stable vision refers to a consistent eyeglass or contact lens prescription over a period of six months to one year. Minor fluctuations in vision are common, but significant prescription changes can indicate that the eye’s refractive state is still shifting. Because refractive surgery is customized to correct the current prescription, performing the procedure before stability is reached could result in undercorrection or overcorrection if the eyes continue to change afterward.

Why Vision Stability Matters in Surgery Planning

Achieving stability before surgery helps ensure predictable and lasting results. The laser or lens-based procedure is programmed to match the unique curvature and refractive properties of your cornea or lens at the time of treatment. If those parameters change later, the correction will no longer be optimal. 

This is especially important for younger patients, whose eyes may continue to change slightly into their mid-twenties, and for individuals experiencing vision fluctuations due to systemic conditions or hormonal factors.

By confirming prescription stability, the ophthalmology team at Schwartz Laser Eye Center can determine whether the corneal shape, ocular surface, and refractive error measurements are appropriate for permanent correction. Establishing this baseline reduces the likelihood of future enhancement procedures and supports accurate long-term outcomes.

How Stability Is Determined

During a refractive surgery consultation, detailed diagnostic testing is performed to measure corneal topography, thickness, and overall refractive power. Your clinical history and past prescriptions are also reviewed to identify any changes over time. Consistency in these measurements confirms that the visual system is stable enough for surgery. If changes are observed, your eye doctor may recommend a period of observation before proceeding to ensure that your vision remains steady.

Comprehensive Evaluation at Schwartz Laser Eye Center

Refractive surgery is always preceded by a detailed assessment that considers ocular health, corneal structure, and prescription history. At Schwartz Laser Eye Center in Scottsdale, Glendale, and Mesa, AZ, each patient receives an individualized evaluation to confirm candidacy and timing for surgery. This careful approach allows the team to create a precise, customized surgical plan once stability has been verified.

While CLE is primarily performed to reduce dependence on glasses or contact lenses, it may also offer an added benefit: helping to limit the need for future lens-related procedures. Here, our team discusses some ways that CLE supports long-term vision stability.

The Dual Role of Clear Lens Exchange

CLE is designed to address refractive errors such as farsightedness, nearsightedness, and presbyopia by removing the natural lens and implanting a clear artificial lens. Unlike laser-based procedures that reshape the cornea, CLE modifies the internal optical system of the eye. This approach allows for a high degree of visual correction and may be suitable for patients with high prescriptions or age-related lens changes.

Importantly, because CLE involves removal of the natural lens, it also eliminates the possibility of cataract development in the future. Cataracts occur when the natural lens becomes cloudy with age, but that cannot happen once the lens has been replaced. This aspect of CLE may limit the need for future lens-based procedures, including cataract extraction.

Minimizing Future Surgical Intervention

Patients who undergo CLE often benefit from long-term visual stability, especially when combined with the selection of an appropriate intraocular lens (IOL). The lens chosen during surgery is matched to the patient’s refractive measurements, lifestyle, and ocular anatomy. For many, this approach may reduce the likelihood of needing additional surgical intervention related to lens clarity or focus.

While CLE does not prevent all age-related changes in vision, such as those that occur at the retinal or corneal level, it does proactively address the most common internal optical changes associated with aging. This may help patients maintain clearer, more consistent vision for years after the procedure.

Comprehensive Consultation and Planning

At Schwartz Laser Eye Center, our eye doctors use a thorough preoperative evaluation process (including biometry, corneal imaging, and ocular health assessments) to determine whether CLE is appropriate. This individualized approach ensures each treatment recommendation aligns with both current visual needs and long-term eye health considerations.

What Is Clear Lens Exchange?

Clear lens exchange, also called refractive lens exchange (RLE), involves replacing the eye’s natural lens with a customized artificial intraocular lens (IOL). This procedure is similar to cataract surgery but is performed before cataracts develop, making it a proactive approach to correcting presbyopia.

One of the most significant benefits of clear lens exchange is its ability to provide long-lasting vision correction. By replacing the aging natural lens, CLE eliminates the root cause of presbyopia. Modern intraocular lenses can also correct other refractive errors, such as nearsightedness, farsightedness, and astigmatism, reducing or eliminating the need for glasses or contacts.

Customized Intraocular Lens Options

Patients undergoing clear lens exchange can choose from a variety of advanced IOLs designed to meet their individual vision needs. Options include:

• Multifocal IOLs: These lenses allow for clear vision at near, intermediate, and far distances.
• Extended Depth of Focus IOLs: Designed for a smooth transition between distances, minimizing the need for glasses.
• Toric IOLs: Ideal for patients with astigmatism.

With these advanced lens options, clear lens exchange can be tailored to match a patient’s lifestyle and visual priorities.

Quick Recovery and Lasting Results

Clear lens exchange is a quick outpatient procedure with minimal downtime. Most patients notice a significant improvement in vision within a few days, and full recovery typically occurs within a few weeks. Once the procedure is complete, the results are permanent, providing lasting clarity and visual freedom.

Prevents Cataract Development

Another advantage of clear lens exchange is that it prevents cataracts from forming later in life. Cataracts, which affect about half of all adults over 75, occur when the natural lens becomes cloudy over time, leading to diminished vision. By proactively replacing the natural lens, CLE eliminates the possibility of cataracts, reducing the need for future surgery.

Is Clear Lens Exchange Right for You?

While CLE is particularly beneficial for patients who are not candidates for laser vision correction procedures like LASIK or PRK, many people who are candidates for laser refractive surgery still choose CLE given its numerous benefits. At Schwartz Laser Eye Center, our ophthalmologists use advanced technology and extensive experience to deliver exceptional results with clear lens exchange.

About Clear Lens Exchange

Clear lens exchange is an outpatient procedure that involves the use of an IOL to help you see clearly. The IOL contains a vision prescription that is customized to your eyes. The procedure can take as few as 15 minutes, and many patients feel ready to jump back into their normal activities within a few days or weeks after surgery. After the IOL is placed, it functions like your natural lens. It effectively bends light entering the eye so that it lands properly on the retina, giving you crisp vision.

Following a clear lens exchange, many patients are able to reduce or eliminate their dependence on other vision correction options, allowing them to drive, read, swim, and engage in countless activities without the hassle of glasses or contacts.

Your IOL Options

Each IOL serves a different purpose. Dr. Schwartz will evaluate your case and help you determine which lens is best for you. Options include:

Monofocal IOLs: This lens is designed to have a fixed focus for only one distance.

Multifocal IOLs: Multifocal IOLs provide vision correction at a range of distances.

Accommodating IOLs: Accommodating lenses react to eye muscle movements, which allows the patient to easily shift focus at multiple distances.

Extended depth of focus IOLs: This newer type of IOL provides patients with a wider range of vision.

Candidates

To determine your candidacy, Dr. Schwartz will conduct an evaluation with you, where you will have the opportunity to ask questions and receive clarity on the procedure and how it can fully benefit you. In general, candidates for clear lens exchange share the following characteristics:

• Are extremely nearsighted or farsighted
• Have presbyopia, which is age-related farsightedness
• Want to reduce their reliance on glasses and contacts
• Are not candidates for LASIK or PRK

Why Is My Doctor Recommending Clear Lens Exchange Instead of LASIK?

While both surgeries will address refractive errors, LASIK is most effective on patients under the age of 40. Because the eyes start going through changes again around the age of 40, clear lens exchange, also known as clear lens exchange or CLE, generally becomes the better option for patients who are middle age and older.

Your doctor may also recommend clear lens exchange if you have moderate to severe farsightedness. LASIK does not correct hyperopia beyond a certain level, whereas this alternate procedure can.

Is Clear Lens Exchange Safe?

Because clear lens exchange is a more involved procedure than laser surgeries, there is a slightly higher complication rate for CLE than LASIK. With that said, the risks are still exceedingly low and the doctors at Schwartz Laser Eye Center have achieved great outcomes for their patients who choose this procedure. Studies have found that about 95% of patients who undergo clear lens exchange have markedly better vision afterwards.

What Is the Difference Between Monofocal and Multifocal Lenses?

The eye’s natural lens can be replaced with a monofocal or multifocal lens. Monofocal lenses have a single point of focus (most are set for distance vision). If a patient with a monofocal lens also has trouble seeing up close, reading glasses may still be necessary. Multifocal lenses have multiple points of focus, making them more ideal to see at distances near and far. While more useful, multifocal lenses come at a premium and are less likely to be covered by insurance plans.

Your doctor will be able to recommend a specific type of IOL based on eye tests, your personal preferences and your budget.

How Does Clear Lens Exchange Prevent Cataracts?

The cloudiness from cataracts only forms on natural eye lenses. When you have an IOL in your eye, that guarantees that cataracts will not develop. In fact, cataract surgery is essentially the same procedure as clear lens exchange in that they both remove the natural lens and replace it with a synthetic lens.

Considering that nearly half of all adults over the age of 75 will develop cataracts, having clear lens exchange now can help you to avoid this plausible outcome in later years.
