Clear Lens Exchange: What it is, surgery & recovery

Eye health is essential to overall well-being, and for many individuals, restoring clear vision involves undergoing eye lens replacement. This advanced procedure is commonly used to improve vision affected by conditions such as cataracts or presbyopia, helping patients regain sharp and comfortable eyesight for daily activities.

In this blog, we explain everything you need to know about eye lens replacement, including the procedure, types of intraocular lenses (IOLs), and what to expect during recovery.

What is a clear lens exchange?

Clear lens exchange, also known as refractive lens exchange, is a surgical procedure where the eye’s natural lens is removed and replaced with an artificial intraocular lens (IOL). This treatment is commonly used for:

  • Cataracts (clouding of the natural lens)

  • Presbyopia (age-related loss of near vision)

  • Severe refractive errors (e.g., high myopia or hyperopia)

It is similar to cataract surgery but may also be offered as a vision correction alternative for people who are not suitable candidates for LASIK or PRK.

When is a clear lens exchange recommended?

Clear lens exchange is typically recommended for patients who:

  • Have been diagnosed with cataracts that affect daily activities like reading, driving, or working.

  • Experience blurred or cloudy vision, halos around lights, or trouble seeing at night.

  • Wish to reduce or eliminate dependence on glasses or contact lenses.

  • Have significant age-related vision changes such as presbyopia.

  • Are not eligible for corneal-based laser vision correction.

A thorough eye examination and detailed diagnostic imaging are essential to determine eligibility for lens replacement and to select the most suitable intraocular lens (IOL) based on individual lifestyle and vision needs.

Types of Intraocular Lenses (IOLs)

During a clear lens exchange, your natural lens is replaced with one of the following IOLs:

  • Monofocal IOLs

      • Designed to focus at one distance (near, intermediate, or far).

      • Typically chosen for clear distance vision, with glasses needed for reading.

  • Multifocal IOLs

      • Provide vision at multiple distances.

      • Can reduce or eliminate the need for glasses after surgery.

  • Toric IOLs

      • Correct astigmatism along with other refractive errors.

      • Available in monofocal and multifocal designs.

  • Extended Depth of Focus (EDOF) IOLs

    • Provide a broader range of clear vision from distance to intermediate.

    • Designed to reduce visual disturbances like halos or glare.

Clear lens exchange surgery: step-by-step

Here is what to expect during the procedure:

1. Pre-operative assessment

You will undergo a comprehensive evaluation that includes:

  • Visual acuity tests.

  • Eye pressure (or intraocular pressure) checks.

  • Measurements of the eye (biometry)

  • Corneal topography and imaging.

2. Day of surgery

  • The procedure is performed under local anaesthesia with numbing eye drops.

  • A tiny incision is made in the cornea.

  • The cloudy or aged lens is broken up using ultrasound (phacoemulsification) and gently removed.

  • A new IOL is implanted through the same small incision.

  • The incision is self-sealing, so stitches are usually not required.

The entire procedure typically takes 15–30 minutes per eye.

Recovery after clear lens exchange

Immediately post-surgery

  • Most patients go home the same day.

  • You may experience mild discomfort, light sensitivity, or blurred vision for the first few days.

  • Avoid rubbing your eyes and follow the prescribed eye drops routine to prevent infection and inflammation.

First week

  • Vision usually improves within a few days.

  • Resume light activities such as walking, watching TV, and reading.

  • Avoid strenuous activity, swimming, and makeup near the eyes.

One month

  • Most people achieve stable, improved vision within 2–4 weeks.

  • Regular check-ups will monitor healing and IOL position.

  • Glasses may still be needed depending on the type of IOL chosen.

Benefits of clear lens exchange

  • Restores clear and bright vision.

  • Eliminates cataracts permanently.

  • Reduces or eliminates need for glasses or contacts.

  • Offers long-term solutions with permanent IOLs.

  • Enhances quality of life through improved independence and safety.

Risks and considerations

While generally safe and highly effective, eye lens replacement does carry some risks, including:

  • Infection or inflammation.

  • Glare or halos.

  • Dry eyes or temporary discomfort.

  • Retinal detachment (rare).

  • Need glasses for some tasks.

FAQs

No, typically one eye is treated at a time. The second eye is scheduled after the first eye has healed, usually within a few days to a few weeks.

Preparation includes stopping certain medications, arranging transportation, and avoiding food or drink for a few hours before the procedure as advised by your doctor.

Yes, patients are usually awake but given numbing eye drops and mild sedation to stay comfortable and relaxed during the procedure.

The implanted intraocular lens (IOL) is designed to last a lifetime and typically does not require replacement.

Yes, depending on the type of IOL chosen—such as multifocal or extended depth of focus (EDoF) lenses—both near and distance vision can be corrected.

The surgeon uses advanced instruments to stabilise the eye, and involuntary movement is minimal. Local anesthesia ensures you feel little to no sensation.

Most patients can resume driving after a week, once their vision is clear and they have been cleared by the surgeon during the follow-up visit.
