1. In-the-bag toric intraocular lens implantation in the case of an anterior capsule tear: a case series
RESUMO Objetivo: Analisar os resultados do implante de lentes intraoculares tóricas para rupturas capsulares anteriores durante a facoemulsificação. Métodos: A coorte desta série retrospectiva, consecutiva e intervencional de casos que inclui 8 pacientes. Um paciente foi excluído quando a lágrima foi usada para aumentar a rexe. O astigmatismo pré-o

2. Long-term efficiency of cataract surgery with hydrophilic acrylic Ioflex intraocular lens
OBJECTIVE: To evaluate the efficiency of long-term cataract surgery using low-cost intraocular lens implantation in community campaigns. METHODS: Fifty-eight randomly selected patients were evaluated four years after phacoemulsification and Ioflex intraocular lens implantation. Causes of low visual acuity related to the intraocular lens were evaluated, and

3. Trypan blue 0.1% action analysis on anterior capsule and lens epithelial cells: immunohistochemistry and ultrastructural study / Análise da ação do azul do tripano a 0,1% na cápsula anterior e no epitélio subcapsular do cristalino: estudo imunohistoquímico e ultraestrutural
O objetivo do estudo foi analisar a cápsula e o epitéilo subcapsular cristaliniano (ESC) de pacientes submetidos à capsulotomia curvilínea contínua (CCC) utilizando o corante azul de tripano (AT) a 0,1%, através de microscopia óptica (MO), da técnica TUNEL, de imunohistoquímica e de microscopia eletrônica transmissão (MET). Realizamos um estudo pr

4. Estudo comparativo das estruturas do segmento anterior de olhos de cães com catarata, portadores e não portadores de Diabetes mellitus, avaliadas por biomicroscopia ultra-sônica / Comparison of anterior ocular segment structures in dogs with diabetic or no diabetic cataract, by ultrasound biomicroscopy
Cataracts is the opacity of the lens or its capsule and represent the leading cause of blindness in dogs. The most common cause of cataract in dogs is a result of inherited alteration of the lens protein metabolism, metabolic alterations caused by Diabetes mellitus (DM) are the second most common cause. This is one of the most prevalent endocrinopathy in dog

5. Ultrastructural observations on (pseudo-) exfoliation of the lens capsule: a re-examination of the involvement of the lens epithelium.
One lens each from 2 separate patients suffering from pseudoexfoliation and one lens from a normal eye were examined ultrastructurally. The normal lens capsule was internally lamellar in places and externally of a somewhat reduced electron density but otherwise of a homogeneous appearance and free of inclusions. Observations on the abnormal lenses revealed a

6. Capsular 'pits' in the human lens.
The lens capsule is an atypical basement membrane surrounding the lens epithelial cells and lens fibres which make up the remainder of the human lens. A seemingly unreported morphological change visible in the lens capsule with the biomicroscope is described.

7. Trabeculotomy in pseudoexfoliation of the lens capsule.
Trabeculotomy was performed on 12 eyes of 11 patients with glaucoma associated with pseudoexfoliation of the lens capsule. Pressure was lowered in all eyes, in 10 eyes to 15 mmHg or less, 7 with no medication but 3 with medication. A subconjunctival bleb was present in 5 patients but was not necessary for a good result. These results suggest that the raised

8. The human anterior lens capsule--an attempted chemical debridement of epithelial cells by ethylenediaminetetracetic acid (EDTA) and trypsin.
The addition of edetic acid (EDTA) or trypsin to the infusion during a simulated extracapsular cataract extraction on cadaver eyes facilitates the removal of lens epithelial cells from the anterior capsule. Modification of the chemical composition of infusions used during extracapsular surgery may maximise lens epithelial cell removal and hence reduce the in

9. Lens fringe in homocystinuria.
The lens from a patient with homocystinuria was examined by scanning and transmission electron microscopy. A fringe of zonular remnants was found attached to the anterior lens capsule, and was observed to be composed of masses of short filaments in disarray, together with occasional bundles of normal-appearing zonular filaments. Although a pericapsular membr

10. Posterior lens capsule abscess due to Propionibacterium acnes and Staphylococcus epidermidis following extracapsular cataract extraction.
A case of posterior lens capsular abscess occurring many months after an extracapsular cataract extraction is presented. This was caused by a mixed infection involving Propionibacterium acnes and Staphylococcus epidermidis. The significance of Staph epidermidis after such a long postoperative period is uncertain, but the case shows features typical of second

11. Alterations of the anterior lens capsule associated with climatic keratopathy.
We describe changes in the anterior lens capsules of older people in Somalia, a country which is close to the equator and with large areas of sand, often highly reflective of sunlight. The capsule changes are confined to the central pupillary area. In order of apparently increasing severity they consist of a white opalescence ('frosting'), an elevation in fr

12. In vivo human lens epithelial cell proliferation on the anterior surface of PMMA intraocular lenses.
AIMS: To study in vivo human lens epithelial cell proliferation on the anterior surface of PMMA implants and its interaction with postoperative blood-aqueous barrier breakdown in eyes undergoing cataract surgery. METHODS: A prospective study was carried out on three consecutive patient cohorts undergoing cataract surgery with intraocular lens implantation us
