OBJECTIVE To examine the development of age-related cataract in a trial of beta carotene supplementation in men. DESIGN Randomized, double-masked, placebo-controlled trial. METHODS Male US physicians aged 40 to 84 years (n = 22 071) were randomly assigned to receive either beta carotene (50 mg on alternate days) or placebo for 12 years. MAIN OUTCOME MEASURES Age-related cataract and extra...

The changes in corneal curvature were determined at regular intervals over a one-year period following intracapsular cataract extraction by microsurgical techniques. During the first postoperative month photokeratometric measurements showed rapid changes in astigmatism associated with large changes in the direction of the axis. Thereafter astigmatism against-the-rule predominated. Data from the...

COMMUNITY EYE HEALTH JOURNAL | VOLUME 30 | NUMBER 100 | 2017 The first record of cataract being surgically treated is by Susruta, who carried out the procedure in 600 BC. Cataracts were treated using a technique known as couching, in which the opaque lens is pushed into the vitreous cavity to remove it from the visual axis. Couching is still performed in some parts of Africa and the Middle East...

IN 1953 I described an erisophake (Esposito, 1953), which I had devised in 1950, and which I had been, and have been, using since that time in cataract surgery. Since the original article appeared, this instrument has been used successfully and extensively by many ophthalmologists as noted by many writers, including Hope-Robertson (1954) and Givnor (1953). Of interest has been the attempted mod...

PURPOSE To examine anterior chamber depth (ACD) and anterior chamber angle (ACA) in patients with glaucoma after cataract extraction with an anterior optical coherence tomography (OCT) system. METHODS A new commercially available 1310 nm infrared light anterior segment OCT system was used for anterior chamber evaluation. Sixty patients (n=20 with primary open angle glaucoma [POAG], n=20 with ...

INTRODUCTION This study aims to describe the preferences of ophthalmic anaesthesia for cataract extraction among ophthalmologists in Singapore. METHODS A nationwide questionnaire survey of all cataract surgeons in institutional and private practice in Singapore was conducted in August 2004. RESULTS The response rate was 61.1 percent (88 out of 144 eligible ophthalmologists surveyed). Phacoe...

AIM to evaluate morphological changes in the posterior lens capsule (LC) after different techniques of cataract extraction. MATERIAL AND METHODS Eight pseudophakic human autopsy eyes were divided into two groups by the technique used for cataract extraction. Group 1 included 4 eyes following extracapsular cataract extraction (ECCE) and rigid IOL implantation. Group 2 included 4 eyes after min...

BACKGROUND Metabolism of many of the most commonly consumed carbohydrates in the United States results in a high plasma glucose response, which can be quantified by the glycemic load. Although hyperglycemia is a risk factor for cataract, there is no information on the potential effect of a high dietary glycemic load on the incidence of age-related cataract. OBJECTIVE Our objective was to pros...
