[Functional evaluation of the corneal endothelium using anterior segment fluorophotometry]

The AA have studied the permeability of the corneal endothelium by anterior segment fluorophotometry using instillation of fluorescein. The Fluorotron Master TM has been modified with the introduction of a new slit (58.4 microns) and of the voltage output (6.5 v) has also been increased. The resolution has been improved from 2.39 mm to 0.59 mm. Of this study, we have examined 20 patients submitted to extracapsular cataract extraction with intraocular lens implantation (ECCE + IOL). The patients have been divided in two groups, according to the surgical technic used: "can-open" and intracapsular. Each patient have been submitted before surgery and 1 week after to an ophthalmologic examination, paquimetry and anterior segment fluorophotometry. The permeability coefficient (PAC) increases with the duration of surgery and when using "can-opener" instead of endocapsular.
