The Technological Revolution: LAL

The journey of vision correction technology is marked by significant milestones, each one bringing us closer to achieving the best possible results for patients. The latest revolution in this field is the Light Adjustable Lens (LAL), a truly groundbreaking innovation that was FDA approved in 2017. Vision correction technology has come a long way since the invention of eyeglasses around the 13th century. From then on, significant strides have been made in this field, eventually leading up to the development of the Light Adjustable Lens (LAL). Let’s take a brief walk through this evolution:

  1. Eyeglasses: Eyeglasses are the earliest form of vision correction technology, dating back to Italy in the late 13th century. Over time, glasses evolved to correct a variety of refractive errors, including myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism. Bifocal and multifocal lenses were introduced in the 18th century, helping people with presbyopia (age-related farsightedness) see clearly at different distances.
  2. Contact Lenses: Contact lenses were the next significant breakthrough, first introduced in the late 19th century. Early contact lenses were made from glass, then hard plastic. In the 1960s, soft contact lenses were invented, offering improved comfort. The 1970s saw the introduction of gas permeable rigid lenses, which offered the clarity of hard lenses with the comfort of soft lenses.
  3. Refractive Surgery: Starting from the mid-20th century, various refractive surgeries were developed to correct refractive errors permanently. Procedures like radial keratotomy (RK) and photorefractive keratectomy (PRK) were precursors to LASIK, which was widely adopted in the late 1990s and early 2000s. LASIK is approved by the United States Food and Drug Administration and uses a laser to reshape the cornea, correcting refractive errors. Its success spurred the development of other laser-based procedures like PRK and SMILE.
  4. Intraocular Lenses (IOLs): IOLs, introduced in the 1940s, were initially used to replace the natural lens after cataract surgery. IOL implantation evolved over time, and now, multifocal and toric IOLs can correct presbyopia and astigmatism, respectively.
  5. Phakic IOLs: In the 1950’s, phakic intraocular lenses were developed. Unlike standard IOLs, these lenses are used in addition to the natural lens to correct severe myopia or hyperopia.
  6. Corneal Inlays and Onlays: Corneal inlays and onlays are small, thin devices implanted into the cornea. They were developed in the 1940’s to correct presbyopia.
  7. Light Adjustable Lenses (LAL): The most recent advancement in vision correction technology is the Light Adjustable Lens. These advanced IOLs, made of a special photosensitive material, are implanted into the eye to replace the natural lens, similar to traditional IOLs. However, LALs can be further adjusted post-operatively using UV light to fine-tune the patient’s vision, ensuring the best possible visual outcome.

LALs are intraocular lenses (IOLs) made of a special photosensitive material that allows for customized vision correction. Unlike traditional IOLs, which are pre-set with a fixed focusing power, LALs are adjustable and adaptable. Once implanted into the eye, the refractive power of these lenses can be fine-tuned using UV light, allowing us to correct vision with unprecedented precision. The customizable and adjustable vision correction that LALs provide is life-changing and raises the bar when it comes to vision correction.

There are several advantages to this approach. Improved visual acuity is the most immediate benefit, but the flexibility of LALs also allows surgeons to address common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism with greater accuracy than ever before. Furthermore, the potential for post-operative adjustments means that we can refine the results to best suit the patient’s needs and lifestyle.

The Science behind LAL

At the heart of the LAL technology is a unique photosensitive material that changes shape when exposed to UV light. When targeted UV light is applied to the lens, it alters the shape of the photosensitive material, changing the refractive power of the lens. This innovative interaction between UV light and the photosensitive lens material is what allows us to adjust and fine-tune vision correction.

The development of Light Adjustable Lenses (LALs) represents years of dedicated research, extensive trials, and rigorous testing. A significant amount of work has been devoted to the materials science, surgical procedures, and post-operative care associated with this innovative technology.

The photosensitive material is composed of a silicon-based polymer embedded with special photoreactive macromers. This substance was the result of years of research in polymer chemistry. The aim was to find a material that responds to receiving light exposure, allowing the lens to change shape, and thereby altering the refractive properties. This photosensitive material needed to be biocompatible, ensuring that it was safe for implantation in the human body, and it also needed to be stable enough to provide long-term vision correction.

Researchers also had to ensure the lens adjustment would be precise and reliable after implantation. Additionally, manufacturing processes needed to be developed to produce these lenses with consistent quality.

The development of a system to deliver the UV light in a controlled and precise manner was another critical part of LAL research and development. This led to the creation of the Light Delivery Device (LDD), which emits controlled amounts of UV light to achieve the desired lens adjustments.

Before approval, LALs underwent rigorous clinical trials to demonstrate their safety and efficacy. These trials took several years and involved multiple stages, including initial safety tests, small-scale trials to demonstrate potential effectiveness, larger trials to confirm efficacy, and post-marketing studies to monitor long-term results.

Finally, the development of LALs also required research into the surgical techniques for implanting the lenses and the post-operative care required for patients. This includes the lens adjustment process and patient guidelines to prevent premature adjustment due to accidental UV exposure.

The development of Light Adjustable Lenses represents a significant achievement in vision correction technology, showcasing how years of dedicated research can lead to innovative solutions. The LALs have the potential to provide a more personalized, precise form of vision correction that could significantly improve the quality of life for many patients.

The LAL Adjustment Process: Precision and Flexibility

One of the key advantages of LAL technology is the adjustment process, which is non-invasive and conducted as an outpatient procedure. Typically, this process involves 2-3 sessions of targeted UV light application, which can be comfortably carried out at our Brinton Vision clinic.

A customized prescription is created for the patient based on their lifestyle needs and refraction, and then a short and painless procedure using an in-office Light Delivery Device (LDD) is used to customize the IOL using UV light. A UV light source, electronic control circuit, and an additional optical projection system make up the LDD. A contact lens put over the cornea concentrates the UV light on the IOL.

This precision of this process allows for the lens’ refractive power to be fine-tuned post-surgery, an approach that was previously unachievable with traditional IOLs. This fine-tuning capacity opens up new possibilities in vision correction, allowing us to address subtle changes in vision that would have been challenging to correct with previous technologies.

The adjustment process of the Light Adjustable Lens (LAL) is a unique and crucial aspect of its function, allowing for precise vision correction after the initial eye surgery.

Here’s how the process typically works:

  1. Healing Period: After the initial surgery, where the LAL is implanted, there is a healing period. During this time, the eye and the newly implanted lens adjust naturally to each other as the eyes heal. This healing process can vary from person to person, but it typically takes a few months to settle into position.
  2. First Adjustment Session: Once your eye has sufficiently healed, the first adjustment session is scheduled. In this session, the eye is exposed to a precise amount of ultraviolet (UV) light using a device called a Light Delivery Device (LDD). This UV light exposure triggers a reaction in the photosensitive material of the LAL, changing its shape to better correct vision. This process is non-invasive and usually takes about 4-5 minutes. The changes made to the lens are based on the individual’s visual needs, which are determined through a comprehensive eye examination and measurements.
  3. Evaluation: Following each UV light treatment session, your vision will be assessed to see how well the adjustment has worked and whether further changes are needed.
  4. Additional Adjustment Sessions: If necessary, additional sessions are scheduled to further refine your vision after having the lens adjusted initially. Generally, 2-3 adjustment sessions are available to achieve optimal vision correction, but this can vary based on individual needs.
  5. Lock-in Procedure: After the final adjustment session, a “lock-in” treatment is performed. This lockin treatment involves applying a different wavelength of UV light to the lens to cease its photosensitivity, thus preventing any further changes in its shape. After this, the adjustment process is considered complete, and the lens should provide stable vision correction.
  6. Follow-up Care: Regular follow-up appointments with your ophthalmologist are recommended to monitor your eye health and ensure the LAL is functioning as intended.

It’s important to note that during the adjustment process, patients are required to wear UV-protective glasses to prevent unintended changes to the lens implants from exposure to natural sunlight or other sources of UV light. This is necessary until the “lock-in” procedure is completed.
