Study Summary
Cataract, in which the lens of the eye is opacified, is the major cause of blindness. This study will examine protein material of the lens called crystallins to try to determine what causes nuclear cataracts, a type of cataract that forms in the central lens nucleus. Men and women age 45 years or older with a cataract may be eligible for this study. Candidates will be screened to determine what type of cataract they have and will undergo a complete eye examination, including a vision test, eye pressure test, and examination of the lens and retina. Patients selected for study will have a complete physical and eye examination, including photography of various parts of the eye, and ultrasound measurements of the eye. They will then have cataract surgery, either with or without intraocular lens implantation, and will have follow-up examinations 1 week, 3 weeks, 5 weeks and 8 weeks after surgery. Tissue from the lenses removed during surgery will be given to NEI scientists for research on the causes of age-related nuclear cataracts.
