A (Prospective/Pilot) Study Evaluating the Effect of Cataract Surgery on the Daily Activity Levels of Elderly Patients

University of Pikeville

Overview

To evaluate the effect of bilateral cataract surgery with intraocular lens implantation on the daily activity levels of elderly patients.

Cataract formation is a natural aging process that can be influenced by environmental factors such as exposure to ultra violet light and diet. Additionally, metabolic disorders, such as diabetes can lead to an earlier development of cataracts. As cataracts develop, a patient's vision can be affected. Reduced vision can limit activities of daily living and may even reduce a patient's mobility. When this occurs, cataract surgery should be considered to help restore a patient's vision. With the obesity and diabetic epidemic, proper diet and exercise is a major health initiative to control these diseases. If a patient's mobility is reduced as a result of poor vision - their ability to achieve adequate daily physical activity may also be effected. It is thought that improvement in vision may increase their activity levels and help combat these health issues. This study will investigate the activity level of patients before and after undergoing cataract surgery to determine how improved vision quality from removal of the natural lens inside the eye and replacement with an artificial intraocular lens effects their activity level.
