Plain English Summary
Background and study aims
Cataracts occur when changes in the lens of the eye cause it to become less transparent, causing cloudy, blurry, or misty vision. Cataract surgery involves removing the cloudy lens through a small cut in the eye and replacing it with a clear, plastic lens. The aim of this study is to assess the benefits of showing patient education videos to patients considering cataract surgery.
Who can participate?
Patients undergoing cataract surgery for the first time
What does the study involve?
Participants are randomly allocated to either watch the educational video before meeting with their surgeon for counselling, or to just receive face-to-face counseling with their surgeon. Participants are then asked to complete a short questionnaire at the end of their visit to assess their comprehension and satisfaction.
What are the possible benefits and risks of participating?
Participants may learn more about their surgery by viewing a patient education video. No risks are anticipated as the video shown was carefully produced by the American Academy of Ophthalmology.
Where is the study run from?
Gavin Herbert Eye Institute at the University of California, Irvine (USA)
When is the study starting and how long is it expected to run for?
June 2017 to September 2017
Who is funding the study?
