[Unintentional staining of lens posterior capsule with trypan blue during extracapsular cataract extraction: case report].
Report of a complication related to the use of 0.1% trypan blue during capsular staining of the anterior crystalline lens capsule in an extracapsular cataract extraction with intraocular lens implantation. The capsular dye was injected using an air-bubble technique, inadvertently, it was done using high pressure dispersing the dye through the zonules leading to a complete lost of red reflex, the following steps of the procedure becoming more difficult after the cataract extraction and causing a temporary disturbance of visual acuity in the postoperative period. In order to avoid this complication, the authors also describe the use of "Modified air-bubble technique" where dispersive viscoelastic is placed into the iridolenticular space 360 degrees to create a protection barrier.
