Inadvertent Trypan Blue Staining of Posterior Capsule during Cataract Surgery Associated with "Argentinian Flag" Event.
Trypan blue is common in visualizing the anterior capsule during cataract surgery. Inadvertent staining of the posterior capsule during phacoemulsification is a rare complication and there are few reports in the literature. The proposed mechanism of posterior capsule staining in previous reports includes a compromised zonular apparatus or iris retractors facilitating the posterior flow of trypa...
متن کاملCrystalline lens capsule staining with trypan blue.
A 1-step method for staining the anterior lens capsule with trypan blue is described. The dye is instilled via a paracentesis port at the start of cataract extraction. As aqueous humor is allowed to exit the anterior chamber (AC), which consequently shallows, the resulting pupil block confines the dye to the AC. An ophthalmic viscosurgical device (OVD) is used to flush dye-stained aqueous from ...
متن کاملCorneal edema after descemet membrane stripping automated endothelial keratoplasty with the use of gentian violet staining.
In recent years, endothelial keratoplasty has been commonly used as an alternative to penetrating keratoplasty as a surgical treatment for corneal endothelial pathologies. The most common form of endothelial keratoplasty is Descemet membrane stripping automated endothelial keratoplasty (DSAEK), which involves stripping the host’s Descemet membrane and endothelium and replacing them with donor p...
متن کاملTrypan blue assisted phacoemulsification in corneal opacities.
AIM To evaluate the efficacy of trypan blue for enhancing visualisation during phacoemulsification and foldable lens implantation in cases of cataract with corneal opacities. METHODS 11 eyes of 11 patients with nebulomacular corneal opacities involving the visual axis with partially and visually debilitating cataract underwent trypan blue assisted phacoemulsification with foldable intraocular...
متن کاملCorneal donor tissue preparation for Descemet's membrane endothelial keratoplasty.
Descemet's Membrane Endothelial Keratoplasty (DMEK) is a form of corneal transplantation in which only a single cell layer, the corneal endothelium, along with its basement membrane (Descemet's membrane) is introduced onto the recipient's posterior stroma(3). Unlike Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK), where additional donor stroma is introduced, no unnatural stroma-...
