Background and study aims Cataracts are cloudy patches that develop in the lens of the eye and can cause blurred or misty vision. Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens from the eye to improve vision. An artificial intraocular lens is then inserted into the eye. Modern micro-incision cataract surgery aims to reduce the size of the incision needed for the surgery by using smaller intraocular lenses and phacoemulsification tips. This may result in less operative trauma. The aim of this study is to compare a 23 gauge (G) phacoemulsification tip to a conventional 20G phacoemulsification tip for micro-incision cataract surgery. Who can participate? Patients aged 55-88 with age-related bilateral cataracts (i.e., in both eyes) and scheduled to undergo bilateral cataract surgery at our hospital. What does the study involve? A conventional 23G phacoemulsification tip will be used for the cataract surgery in one eye, while in the other eye cataract surgery will be performed with a 20G phacoemulsification tip. The follow-up care will be at our hospital. Visits will be 1 week and 6 months after surgery. The visits will include standard postoperative care and a measurement of the cornea of the eye. What are the possible benefits and risks of participating? Cataract operations are generally very successful, with a low risk of serious complications. We do not expect any additional risk due to participation in the study. There may be no direct benefits for the participants, but the smaller incisions used for the 23G tip may lead to a faster recovery. Where is the study run from? Medical University of Vienna (Austria). When is the study starting and how long is it expected to run for? The study ran from April 2008 to April 2011. Who is funding the study? Medical University of Vienna (Austria). Who is the main contact? Dr Rupert Menapace [email protected]
