C ataract is the leading cause of blindness in the world, and the leading cause of low vision in European derived populations. The burden of cataract is likely to increase as the world’s population ages. At present, no effective means of preventing cataract exists, with the possible exception of smoking cessation. For the foreseeable future, the sole method of preventing cataract blindness will...
BACKGROUND The coexistence of cataract and age related macular degeneration (AMD) is not unusual, especially in the very elderly. The outcome of cataract surgery in these cases depends on the effect of AMD on vision. In this study the authors have compared the outcome of cataract patients with AMD to that of cataract patients with no vision threatening ocular comorbidity, and analysed possible ...
Recently, small incision cataract extraction by phaco and implantation of a foldable intraocular lense with topical anesthesia has used in an attempt to decrease the complication of general anesthesia and peribulbar injection. To compare effects and complications of topical, local and general anesthesia, 92 patients admitted to Imam Hosein hospital for cataract surgery, were randomly assigned t...

BACKGROUND Cataract is a leading cause of vision impairment worldwide, and surgery is the only available treatment. The process that initiates lens opacification is dependent on the oxidative stress experienced by the lens components. A healthy overall dietary pattern, with the potential to reduce oxidative stress, has been suggested as a means to decrease the risk of developing cataract. We ai...
PURPOSE Little is known regarding the extent by which patients undergoing outpatient cataract surgery are at risk for postoperative hospitalization. We sought to determine the percentage of patients undergoing cataract surgery who were subsequently hospitalized, the patient characteristics associated with postoperative hospitalization, and the reasons for hospitalization. METHODS We identifie...
BACKGROUND Cataract day surgery has rapidly gained worldwide acceptance, because the new surgical techniques and costs are generally lower than those involved in ordinary hospitalization. Cataract surgery serves as a proxy indicator of the trend towards day surgery hospitalization in Italy and, therefore, of regional variability in health-care delivery and cost. The aim of this study was to upd...
OBJECTIVE This study utilized a phone survey to characterize patient perceptions of cataract surgery and the manner in which the ophthalmologist contributes to the patient's understanding in electing cataract surgery. PATIENTS AND METHODS Calls were made from a randomized membership list of the American Association of Retired Persons until 1,000 respondents 50 years of age or older had been r...
Age-related cataract is the leading cause of visual loss worldwide, with developing nations carrying most of this burden. The prevalence of cataract doubles with each decade of age after 40 years, such that most people in their 80s and 90s will be affected. Although cataract removal and intraocular lens implantation effectively treats this condition and restores good vision, cataract surgery is...
