The Choice is Clear


Light Adjustable Lens (LAL)

The Light Adjustable Lens (LAL) from RxSight™ is composed of a photosensitive material that allows for vision adjustment following cataract surgery. This IOL is the first lens available for personalized vision enhancement after surgery takes place. Similar to our other IOL options, the Light Adjustable Lens is placed during the cataract removal procedure, but patients will return for a follow-up appointment when their vision will be assessed and adjusted as needed.

Using the Light Delivery Device (LDD), gentle and controlled ultraviolet light is directed at the eye, causing the lens to change shape. The duration of this process will depend upon the extent of a patient’s vision improvement needs, but in most cases treatment is completed within 90 seconds. Approximately three to five adjustment sessions are needed, spaced every three days until the ideal eye prescription is achieved. Once the final adjustment has taken place, the patient’s vision will be secured to ensure no unexpected changes are made in the future.

Trifocal/Extended Depth of Focus IOLs

Trifocal Intraocular Lenses (IOLs) are advanced technology lenses designed to allow patients to see at all distances: near, far, and all distances in between, following cataract surgery or refractive lens exchange surgery. These lenses offer many advantages over single focus (Monofocal) IOLs. In clinical studies, the vast majority of patients who received Trifocal lenses were able to see clearly without glasses at all distances.

There are different types of Trifocal and/or Multifocal IOLs, but in general, each works by focusing light rays that pass through the lens to different focal points on the retina or extending the range of vision. Focusing the light rays to different points on the retina allows images that are at multiple distances from the eye to be seen clearly without requiring glasses. Conversely, Single focus IOLs (Monofocal IOLs) focus light rays on only one point on the retina and are not capable of providing clear vision at multiple distances without the use of glasses or contact lenses.

In clinical studies approximately 85% to 90% of patients who received Trifocal/EDOF IOLs did NOT need glasses for most tasks. A small percentage find that they still need glasses for certain tasks, such as extended reading or computer usage. That being said, thousands of patients attest to the beneficial effects of Trifocal/EDOF lenses and were so satisfied with their results that approximately 94% of them would have lenses implanted again.

There are several different Trifocal/EDOF IOL designs that are approved for implantation at the time of cataract surgery or refractive lens exchange surgery in the United States. Our surgeons have extensive experience implanting each of the available design lenses and will help you choose which lens is best for your individual visual needs.

One of the natural consequences of all Trifocal and/or Multifocal lenses is that they may produce some glare and halos around lights. The amount of light phenomenon varies from person to person, but in general most people adapt very well and enjoy high-quality glasses-free vision for most activities. Be sure to discuss your individual visual needs with one of our doctors so we can help you choose which lens technology is best for you.

Acrysof® Toric® IOL

muliThe Acrysof® Toric® intraocular lens (IOL) is specifically for individuals with astigmatism. This advanced technology IOL corrects astigmatism and can provide excellent distance vision without the need for glasses. Many patients who chose the Acrysof® Toric® IOL are able to see well enough at distance not to require glasses or contact lenses. The Acrysof® Toric® IOL can be combined with LRI (limbal relaxing incisions) for patients with large amounts of astigmatism.
