With traditional intraocular lenses (IOLs), your physician performs measurements before your surgery in order to select the best IOL to try to achieve your vision goals. Once your surgery is complete and the IOL has been implanted, your physician has limited options to adjust the lens power.
With the RxSight™ Light Adjustable Lens, you and your doctor can now customize your vision after your eye has healed from cataract surgery. This is because 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. You and your physician will have the unique ability to adjust and preview your vision until it meets your personal desires and lifestyle requirements.
The cataract removal and IOL implantation procedure are the same as if you selected a non-adjustable IOL. Then, in the weeks that follow, your physician will customize your vision through a series of non-invasive light treatments that take only a few minutes each. You may need 2 to 4 total light treatments over a period of 1 to 2 weeks to reach your vision goals. Once your vision is adjusted, the final light treatment is used to lock in the results.
