Light Adjustable Lens

Cataracts can significantly impact your vision, making it difficult to perform everyday tasks. Fortunately, cataract surgery provides a solution by removing the cloudy natural lens and replacing it with an artificial intraocular lens (IOL). While traditional IOLs offer a fixed vision correction, there is a groundbreaking option available – the Light Adjustable Lens (LAL). The LAL is the first and only premium IOL that allows for adjustments and customization after the initial implantation. In this comprehensive guide, we will explore the features, benefits, and the process of utilizing the Light Adjustable Lens to achieve optimal vision outcomes.

Understanding Cataracts and Traditional IOLs

Cataracts are a common age-related condition that causes the natural lens of the eye to become cloudy, leading to blurred vision. Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). Traditional IOLs provide a fixed vision correction based on pre-surgery measurements and predictions. However, these measurements are estimates and may not always result in the desired visual outcome.

Introducing the Light Adjustable Lens (LAL)

The Light Adjustable Lens (LAL) is a revolutionary advancement in cataract surgery that offers a customizable solution for vision correction. Unlike traditional IOLs, the LAL can be adjusted non-invasively using specialized UV light treatments to modify the lens power and achieve the desired visual acuity. This unique feature sets the LAL apart from other IOLs and provides patients with the opportunity to fine-tune their vision after cataract surgery.

How Does the Light Adjustable Lens Work?

The Light Adjustable Lens is made of a photosensitive silicone material that can be altered in response to UV light. During the adjustment process, a specialized instrument known as the Light Delivery Device (LDD) is used to administer targeted UV light treatments to the lens. The UV light activates photosensitive molecules within the lens, causing them to attach and form polymers, which alters the lens curvature and refractive power. By strategically directing the UV light, the ophthalmologist can make precise adjustments to the lens power and customize the patient’s vision.

Benefits of the Light Adjustable Lens

The Light Adjustable Lens offers several significant benefits for patients undergoing cataract surgery:

  • Customizable Vision: Unlike traditional IOLs, the LAL allows for personalized vision correction tailored to each patient’s unique needs and preferences. By adjusting the lens power after surgery, patients can achieve their desired visual outcomes.
  • Correction of Refractive Errors: The LAL can correct a range of refractive errors, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. This means that patients may no longer require glasses or contact lenses for clear vision after cataract surgery.
  • Enhanced Accuracy: Studies have shown that patients who receive the Light Adjustable Lens are more likely to achieve 20/20 vision without prescription glasses compared to those who receive standard IOLs. One recent study, showed that over 97% of patients who underwent cataract surgery achieved 20/20 vision or better with the LAL. In particular, IOL measurements in patients who previously had LASIK can be notoriously difficult to calculate, and the LAL has proven to be an extremely accurate option for vision correction in these patients. Overall, the LAL offers LASIK-like accuracy in cataract surgery, resulting in improved visual outcomes.
  • Highly Customizable: The LAL’s adjustability allows for precise customization based on the patient’s prescription and lifestyle requirements. This level of customization ensures that patients can maximize their visual acuity and potentially reduce their dependence on glasses or contact lenses.
  • Proven Safety: The Light Adjustable Lens has undergone rigorous testing and received FDA approval for use in cataract surgery. It is a safe and effective option for patients seeking enhanced vision correction.

The Light Adjustable Lens Implantation Process

The process of receiving a Light Adjustable Lens at the Cornea and Laser Eye Institute involves several stages, from pre-surgery consultations to post-operative adjustments. Let’s explore each step in detail:

1. Pre-operative Consultation

During the pre-operative consultation, our expert team will evaluate your eye health and discuss your vision goals. A comprehensive eye examination, including measurements of your eye’s dimensions and refractive error will be performed. This information will guide the selection of the appropriate Light Adjustable Lens for your surgery.

2. Cataract Surgery

The cataract surgery procedure with the Light Adjustable Lens is similar to the refractive  cataract surgery procedure performed with a fixed IOL. At the Cornea and Laser Eye Institute, our surgeons perform femtosecond laser assisted cataract surgery (FLACS), the most advanced cataract surgery available today. The surgical process is typically quick and performed under local anesthesia.

3. Healing and Stabilization Period

After cataract surgery, your eyes will need time to heal and stabilize. This period usually lasts around 2 to 4 weeks. During this time, your eye doctor will closely monitor your healing progress to ensure that your eyes are ready for the adjustment phase.

4. Vision Adjustment Phase

Once your eyes have healed and stabilized, you will begin the vision adjustment phase with the Light Adjustable Lens. This phase involves multiple appointments at our center to fine-tune your vision using the Light Delivery Device (LDD). The LDD delivers targeted UV light treatments to the lens to adjust its power and optimize your vision.

5. Customization and Refinement

The number of light treatments required for optimal vision adjustment varies for each patient. Generally, patients undergo between 2 to 4 light treatments, with each treatment lasting approximately 90 seconds. These treatments are typically spaced out by a few weeks to allow for the evaluation of vision changes and the planning of subsequent adjustments. The goal is to achieve the desired visual acuity and ensure patient satisfaction.

6. Lock-in Treatment

Once you are satisfied with the achieved vision, a final lock-in treatment is performed. This treatment permanently locks the lens from its adjusted position, preventing any further changes. After the lock-in treatment, you can discontinue wearing UV-protective glasses, as the lens is now set for long-term stability.

Is the Light Adjustable Lens Right for You?

The Light Adjustable Lens is an innovative option for individuals seeking a customizable vision correction solution after cataract surgery. Factors such as your eye health, lifestyle, and visual goals will be taken into consideration to determine the most appropriate lens option for your specific needs.

Pros and Cons of the Light Adjustable Lens

As with any medical procedure, it is essential to consider the advantages and potential drawbacks or problems of the Light Adjustable Lens:


  • Customizable vision correction
  • Precise correction of various refractive errors
  • Enhanced accuracy and visual outcomes
  • Potential reduction in dependence on glasses or contact lenses


  • Requires multiple post-operative appointments for adjustments (more than for a fixed IOL)
  • Temporary reliance on UV-protective glasses during the adjustment phase
