CUSTOMIZING YOUR VISION WITH THE LIGHT ADJUSTABLE LENS

Lipstock Cataract Center is proud to be the First in Virginia to provide the Light Adjustable Lens to greatly minimize your need for eyeglasses after cataract surgery. 

For an understanding of cataracts see What are Cataracts, and also see Will I Need Glasses After Cataract Surgery.

The Light Adjustable Lens (LAL) is the first and only FDA approved intraocular lens (IOL) that can be adjusted after cataract surgery to improve vision without eyeglasses.

Before cataract surgery measurements are typically taken to calculate what power intraocular lens should be chosen to replace a patient’s cloudy cataractous natural lens. The goal is to pick a power that will minimize the need for eyeglasses after surgery. Unfortunately, these measurements can only give an estimate of the true lens power needed. Various factors exist which limit the accuracy of this, such as the inaccuracy of the measuring technology itself and the effects of healing on the eye.   

The ability to change the shape of the LAL with a safe and painless 90 second UV light exposure to perfectly match the eye after healing has resulted in the most precise results ever. In fact the FDA study results showed the LAL achieved 20/20 vision without eyeglasses approximately twice as often as other IOL’s.

Because the LAL can be adjusted after the eye has healed enables the result to not only be more precise but also customizable. In fact, the LAL is the ONLY FDA approved IOL that is customizable.  What do we mean by this?

In order to minimize one’s ability to see both far and near without eyeglasses one can choose something called Blended Vision, a Multifocal IOL, or an Extended Depth of Focus IOL. See Will I Need Glasses After Cataract Surgery for a further discussion of these choices.

Only with the LAL can you get to literally see what Blended Vision will be like after surgery and then adjust it to exactly the way you like. This is a revolutionary advance in enabling cataract patients to see both near and far without eyeglasses while maximizing their visual clarity and comfort.

How Does The Light Adjustable Lens Work?

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. Light treatments are delivered in our office with the Light Delivery Device (LDD).

What To Expect Before and After Surgery

The cataract surgery is no different than when any standard IOL is used. Approximately 3 weeks after surgery, once your eye has healed, you return to our office 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. Your doctor will then apply a light treatment that precisely reshapes your implanted lens based on the visual correction that is needed to target your custom prescription. You may need 2 to 4 total light treatments over a period of 1 to 2 weeks to reach your vision goals. During this time you will be provided with UV protective eyeglasses to wear to shield your eyes from daily UV light exposure. At the end of this time, the final light treatment will lock the IOL shape in place and the UV protective eyewear will no longer be needed.

Your vision is tested after your eye heals. You then sample and select your desired vision outcome.
