Frequently Asked Questions about Light Adjustable Lens Portland

The Light Adjustable Lens, an innovation developed right here in the United States, promises unparalleled accuracy and tailoring in visual correction. This intraocular lens (IOL) is crafted from an exclusive silicone material that alters its shape when bathed in different configurations of ultraviolet light. Once the LAL is in place, patients undergo a set of non-invasive light treatments. During these sessions, the implanted lens is exposed to a precise quantum of UV light, refining its refraction and focusing power. The brilliance of the LAL lies in the fact that the lens power is adjustable even after the surgery, guiding patients closer to impeccable vision, thus minimizing dependence on prescription glasses, reading glasses, or contact lenses.

For the residents of Portland and surrounding areas, Tersigni Vision stands as the beacon of hope, offering state-of-the-art vision correction procedures.

Benefits of the LAL Procedure

  1. Precision: One of the standout features of the Light Adjustable Lens procedure is its exceptional precision. Traditional intraocular lenses, once implanted, are fixed in terms of their refractive power. However, with the LAL, adjustments can be made post-operatively by your surgeon. This dynamic capability ensures that vision correction is tailored to the patient’s unique needs and is more accurate than with standard intraocular lenses. This precision extends to addressing minor deviations that can occur during the recovery phase, ensuring optimal results for the patient.
  2. Flexibility: The human eye is complex and each individual’s healing process and response to surgery can vary. There may be shifts in lens positioning, or unexpected refractive outcomes after lens replacement procedures like RLE and cataract surgery. The LAL shines in these scenarios. It offers unparalleled flexibility by allowing for post-operative modifications. Whether it’s to cater to the patient’s evolving visual needs or to rectify unforeseen refractive errors, the ability to adjust the lens power ensures that the treatment remains adaptive and patient-centric.
  3. Reduced Dependence on Eyeglasses: A primary aim of any refractive surgery or corrective lens implant is to enhance visual acuity, ideally eliminating or reducing the need for corrective lenses. With the LAL’s adaptability and precision, patients have a heightened chance of achieving this goal. By being able to fine-tune the lens even after implantation, it optimizes the chances that patients can embrace a life with less dependence on glasses or contact lenses. This not only enhances their visual experience but also offers the freedom and convenience of a glasses-free lifestyle.

Light Adjustable Lens Portland: A Comprehensive Look

The miracle of sight, one of our primary senses, has always been a focal point of medicine. Advances in ophthalmology, the medical branch concerned with the eye, have been stellar, aiming to correct refractive errors and treat eye conditions such as presbyopia and cataracts. While glasses and contact lenses have been traditional solutions, the world of intraocular lens implants offers a more permanent and refined approach. And at the helm of this evolution is the Light Adjustable Lens (LAL).

The Human Eye and Visual Perception

The human eye is a marvel of biological engineering. For us to see, light enters the eye through the cornea, passes through the natural lens, and lands on the retina. This results in visual perception. A refractive error occurs when the shape of the eye prevents light from focusing directly on the retina. This can result in near-sightedness (myopia), far-sightedness (hyperopia), and astigmatism. Another common eye issue is cataracts, where the natural lens becomes clouded, impairing vision.

Enter the Light Adjustable Lens (LAL)

The Food and Drug Administration (FDA) has given its seal of approval to the LAL from RxSight, noting its safety and effectiveness. Crafted using a special photosensitive material, the lens has the unique ability to adjust in power and shape. This means that after lens replacement surgery, wherein the natural lens is replaced with an artificial intraocular lens (IOL), there remains the potential for micro-adjustments.

Such adjustments can be crucial. No surgery, no matter how advanced, can guarantee perfect vision outcomes due to factors like lens positioning and healing responses, which can vary from patient to patient. Enter the Light Delivery Device (LDD), which emits calibrated UV light, enabling the physician to make lens power corrections post-surgery. This process can correct residual refractive errors, bringing the patient’s eye closer to the desired visual acuity.

After a series of non-invasive light treatments – generally two to four sessions – the lens power is locked in using a final lock-in treatment. The patient then enjoys enhanced visual clarity without a total reliance on corrective lenses.
