A cataract is a cloudy area in the normally clear lens of your eye, causing things to look blurry, hazy, or less colorful. Cataracts are a natural part of the aging process and, over time, can lead to vision loss and blindness. When a cataract interferes with your usual activities, such as reading and driving, your physician will likely recommend
cataract surgery

The only treatment for cataracts is to remove the cloudy natural lens and replace it with a clear artificial lens. This lens is called an intraocular lens (IOL). Cataract removal surgery is the most common procedure in the world and is one of the safest and most successful procedures performed today.

Cataract surgery can also ofer the opportunity to correct other visual problems you may experience such as myopia (nearsightedness), hyperopia
(farsightedness), astigmatism (irregularly shaped lens), or presbyopia (diminishing
ability to focus with age).

Until very recently, all IOLs were fixed lenses, without the ability to be adjusted after surgery.

In this traditional workflow, your eye doctor uses pre-surgery eye measurements to estimate the power and type of fixed IOL he or she thinks will provide you with the best vision after surgery.

If the visual target is not achieved, this can only be corrected by glasses, contacts, or additional surgery. Now, with the advent of adjustable IOLs, this is no longer the case.

With the Light Adjustable Lens, you can now customize your vision after your cataract surgery. You will have the unique ability to adjust and preview your vision based on your personal desires and lifestyle requirements.

The Light Adjustable Lens delivers superior visual outcomes that fixed IOLs cannot match. In a study of 600 subjects, those who received the Light Adjustable Lens followed by adjustments were twice as likely to achieve 20/20 distance vision at 6 months without glasses as those who received a standard (fixed) monofocal IOL.

The Light Adjustable Lens is made of a special photosensitive material that changes the shape and power of your implanted lens in response to ultraviolet (UV) light to optimize your vision. These light treatments are delivered in your doctor’s office with the Light Delivery Device (LDD) after your eye has healed.

If you select the Light Adjustable Lens, the first step is to have your cataract safely removed and the adjustable IOL implanted. The cataract removal and IOL implantation procedure is the same as if you selected a fixed IOL.

After your Light Adjustable Lens has been implanted in your eye, it is adjusted to deliver the customized vision you desire. Following surgery there are two major differences with an adjustable lens compared to a fixed lens:

Exposure to indoor and outdoor sources of UV light can cause uncontrolled changes to the Light Adjustable Lens. To prevent this, you will be provided with UV protective glasses to wear immediately following surgery (from time of lens implantation until after the last light treatment is completed).

Twenty-four hours after your final light treatment, no further changes can be made to the implanted Light Adjustable Lens, and you can remove the UV protective glasses and enjoy your custom vision!

Once your eye has healed, you will return to your eye doctor to have your vision tested. During this visit you will be able to preview and compare possible vision outcomes based on your unique preferences and lifestyle requirements before selecting a prescription for your adjustable lens.

To receive the light treatment, you will be placed in front of the Light Delivery Device (LDD). The LDD non-invasively delivers the UV light to precisely reshape your Light Adjustable Lens based on the visual correction that is needed to target your
custom prescription.

Between 3 and 5 total light treatments, each lasting approximately 90 seconds and separated by approximately 3 days, are required. The total number of light treatments is based on achievement of the desired vision outcome that you and your doctor selected.

Once you have achieved your final optimal vision, the lens power is permanently locked in with two final light treatments to prevent any further changes.

The U.S. Food and Drug Administration has approved the Light Adjustable Lens and Light Delivery Device for patients with pre-existing astigmatism of 0.75 diopters or more who are undergoing cataract surgery.

Other commercially available IOLs may be available for the treatment of your cataracts and your doctor will help you determine which lens is right for you.

Ask your doctor to explain the possible risks and benefits of cataract surgery.
