Bacterial contamination in the anterior chamber after povidone–iodine application and the effect of the lens implantation device

Abstract

In uneventful clear corneal phacoemulsification, meticulous technique can prevent antibiotic use during surgery. No difference in anterior chamber bacterial contamination was found between IOL implantation using an injector or a forceps.

Conjunctival Flora Before and After Application of 5% Povidone-Iodine Solution

“…In our survey the most numerous bacterial colonization was Staphylococcus epidermidis and Micrococcus luteus isolated in conjunctiva before the antiseptic solution application and remained some CFU from both species in the patients conjunctivas after the ansiseptic application, as it is described by Bausz [9]. We found Corynebaterium diphteriae in normal conjunctivas before the antiseptic application (sample A), with no clinical significance, because theydid not have in the bacterial cells DNA the structural Gen of Fago B that make it sinthetize its harmful toxin.…”

Molecular biology applied to the laboratory diagnosis of bacterial endophthalmitis

“…Contamination of the anterior chamber by microorganisms of the conjunctival or palpebral flora can occur during intraocular surgery, which can vary from 2.0% to 46.25% (33)(34) . Thus, bacterial DNA can be detected in a small number of specimens of aqueous or vitreous humor collected from patients without evidence of intraocular infection included in control groups (9) .…”

Microbiota conjuntival en el preoperatorio de pacientes que se someterán a cirugía de cataratas

“…Las bacterias aisladas pertenecían a la microbiota de los tejidos perioculares, principalmente el grupo de Staphylococcus coagulasa negativa (Staphylococcus epidermidis y otros) presente en 70% de los cultivos, Staphylococcus aureus (10%), Streptococcus spp (9%), Enterococcus spp (2%), otras especies grampositivas (3%), y especies gramnegativas (6%) 6,8 . La microbiota conjuntival puede ingresar a la cámara anterior, directa o indirectamente, por la manipulación quirúrgica, los instrumentales, el implante del lente intraocular, e incluso, por filtración a través de la incisión en el post-operatorio 7,[9][10][11][12] . Para disminuir el riesgo de las infecciones postquirúrgicas, es necesario conocer la naturaleza de esta microbiota conjuntival en nuestros pacientes, y así recomendar la mejor profilaxis antimicrobiana en cirugía de catarata 7,13 , además constatar si existen factores asociados…”
