Effects of Sun Filters on Age-related Macular Degeneration in People With Lens Implants

This study will test a new method for preventing worsening of age-related macular degeneration (AMD) and for developing imaging methods to follow the very earliest microscopic changes in the disease. The macula is the part of the retina in the back of the eye that determines central vision. AMD can impair central vision, affecting a person's ability to read, drive, and carry out daily activities. Some studies suggest that cumulative exposure to sunlight increases the risk for progression of AMD to the late stage that is often characterized by poor central vision. This study will determine if wearing glasses with a yellow filter over one eye and a red-violet filter over the other eye when outdoors will decrease the rate of change of early-stage AMD in one or both eyes. Patients early-stage AMD who have had cataract surgery in both eyes with implanted lenses may be eligible for this study. Participants undergo the following procedures: * Wear the filter glasses when outdoors between 10:00 a.m. and 4:00 p.m. * Record the time of day and light environment when they use the glasses. * Have an eye examination, pictures of the retina, and a medical history taken at the beginning of the study and at set intervals during the study. The study lasts at least 12 months and may be extended for a longer period of time....
