Astorino & Associates Eye Center
Ophthalmology & Board Certified Ophthalmologists located in Newport Beach, CA
Using a special lens material designed by a Nobel Prize winning scientist, RxSight has developed the first intraocular lens (IOL) that allows you and your physician to optimize your vision following cataract surgery. Dr. Astorino and Dr. Cahoon are proud to offer this revolutionary new lens to you, to best tailor your sight to your unique needs.
Introducing the Light Adjustable Lens™ from RxSight®
Despite numerous advances in modern cataract surgery technologies, only 6 out of 10 cataract patients achieve their targeted vision, and an even smaller percentage achieve excellent vision at all distances.¹ This is because it is very difficult to predict how your eye will heal before your cataract surgery.
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. This optimization is done by your eye doctor after lens implantation through a series of office-based light treatment procedures that take only a few minutes each.
The Light Adjustable Lens delivers superior visual outcomes that non-adjustable IOLs cannot match.² 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 monofocal IOL.
Achieving Customized Vision With the Light Adjustable Lens™
The Light Adjustable Lens is the only adjustable intraocular lens (IOL) available that allows optimization of your vision after lens implantation and healing. If you and your doctor 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 non-adjustable IOL.
What is unique about the Light Adjustable Lens is that once your eye has healed, you 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. Your doctor will then apply a proprietary light treatment that precisely reshapes your implanted lens based on the visual correction that is needed to target your custom prescription. You may need 3 to 5 total light treatments to reach your vision goals.
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 your doctor’s office with the Light Delivery Device (LDD).
Is the Light Adjustable Lens right for me?
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.
What to Expect Following Your Cataract Surgery
After your Light Adjustable Lens™ has been implanted in your eye, it is adjusted to deliver the customized vision you desire. This means that there are 2 major differences following your surgery as compared to a non-adjustable intraocular lens (IOL):
- Required wear of ultraviolet (UV) protective glasses
- Completion of light treatments
Why do I need to wear protective glasses?
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 during all waking hours (from time of lens implantation until after the last light treatment is completed).
Your protective glasses may be removed when sleeping, and may be temporarily removed when showering, washing your face, or applying eye drops as long as you are not exposed to direct sunlight. 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!
How are the light treatments performed?
To receive the light treatment, you will be placed in front of the office-based Light Delivery Device (LDD). The LDD non-invasively delivers the UV light to your Light Adjustable Lens to adjust your vision to the desired target. The system gives your doctor the flexibility to make adjustments and refinements to meet your specific criteria. Following the light treatment, you will be rechecked in approximately 3 days to assess your vision.
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. When you experience the results of your adjustments, you will better understand the value of adjusting and customizing your vision after your surgery.
Once you have achieved your optimal vision, the lens power is permanently locked in with a final light treatment to prevent any further changes.
