Jacques Daviel’s development of cataract extraction was the culmination of observations and insights by others that spanned many centuries. The location of the lens in the eye and the function of the lens in vision puzzled the physicians and scholars of antiquity and medieval times. Even more elusive was an understanding of the true identity of the lens’s dark twin, the cataract. It was not unt...

Cataract is one of the most common eye disorders that causes vision distortion. Accurate and timely detection cataracts best way to control risk avoid blindness. Recently, artificial intelligence-based cataract systems have been received research attention. In this paper, a novel deep neural network, namely CataractNet, proposed for automatic in fundus images. The loss activation functions are ...

BACKGROUND: In developing countries congenital cataract has become an important cause of treatable blindness in childhood. However, difficulty in correcting aphakia is one of the reasons for poor visual outcome. OBJECTIVE: To determine the visual outcome after extra capsular cataract extraction and intra ocular lens implant and factors militating against good visual outcome in children. METHODS...

PURPOSE To assess the association between age-related macular degeneration (AMD) and previous cataract surgery. METHODS We studied 17,987 randomly selected participants from the Korea National Health and Nutrition Examination Survey who were aged ≥40 years and underwent additional ophthalmologic examinations in 2008‒12. The associations between previous cataract surgery and early/late AMD wer...

Background: To assess the incidence and characteristic of cataract surgery in Poland from 2010 to 2015 and to interpret these findings. Patients and methods: Data from all patients who underwent cataract surgery alone or in combined procedures in Poland between January 2010 and December 2015 were evaluated. Patient data were from the national database of hospitalizations maintained by National ...

Eighty percent of all visual impairment can be prevented or cured by considering the two leading causes in world, i.e., uncorrected refractive error and cataract. Cataracts cause vision loss owing to clouding lens, with age being greatest risk factor. Cataract surgery greatly improve is highly effective. It most commonly performed developed countries. Uncorrected resolved simply wearing proper ...

purpose: to evaluate the incidence of pseudoexfoliation syndrome (xfs) in patients with senile cataract who were scheduled for phacoemulsification and intraocular lens implantation (pe + iol) and to compare the outcomes of pe+iol between eyes with and without xfs. method: we retrospectively reviewed 2200 eyes with cataract undergoing pe + iol. all procedures were performed by a single surgeon (...

OBJECTIVES To study bacteria from eye lids and conjunctival sac of patients undergoing cataract surgery before and after the application of antiseptics. MATERIAL AND METHOD Patients undergoing elective cataract extraction in one university hospital were randomly enrolled. Cultures for bacteria and candida were done by swabbing the eye lids before and after cleaning with 4% chlorhexidine gluco...

OBJECTIVE To know the opinions of trainee ophthalmologists on ways to improve cataract surgical rate (CSR) with a view to having insight into actions that should be of high priority for achieving this improvement. METHODS A survey of 27 trainee ophthalmologists using structured self-administered questionnaire. RESULTS Most trainees had a positive view about actions towards raising CSR: Stru...
