A technique to improve an eye cataract early detection and quantitative evaluation of maturity using ultrasound was investigated. A broadband coherent signal, backscattered from an eye lens tissue, was digitized, recorded and processed. A new parameter – lens quality was proposed for the human eye cataract quantitative evaluation. Lens quality reflects two phenomena of ultrasound interaction wi...

The authors aimed to assess the relation between endogenous and exogenous female hormones and the incidence of age-related cataract and cataract surgery. The Blue Mountains Eye Study examined 2,072 women aged 49 years or older during 1992-1994, of whom 1,343 (74.0% of survivors) were reexamined after 5 years, during 1997-1999. Information on reproductive factors and use of hormone replacement t...

AIM To investigate the effects of an informational video on patient expectations and satisfaction with day-stay cataract surgery. METHODS 141 patients undergoing day-stay cataract surgery were randomised into one of two video groups, explaining either what to expect from the cataract surgery or the anatomy of cataract. Patients were surveyed as to their expectations for visual outcome, anxiet...

BACKGROUND Cataract is the leading cause of bilateral blindness in India. It has been reported that cataract is responsible for 50-80% of the bilaterally blind in the country. Cataract formation is a natural part of the ageing process. At present, adequate data are not available regarding the FABP2 and PPARG2 gene polymorphisms and their susceptibility with cataract cases in the North Indian po...

Introduction Cataracts are common. They are the main cause of blindness, with an estimated 17 million people worldwide blind from cataract. By way of comparison, six million are estimated to be blind from onchoceriasis, trachoma and other causes of corneal opacity. Presently, the only known treatment for cataract is the surgical removal of the lens. The number of cataract operations performed i...
