Evaluation of endothelial cell function with anterior segment fluorophotometry in pseudophakic patients
1987
Abstract Determining fluorescein permeability of the endothelial cell layer provides information on the endothelial cell barrier. Following topical application of fluorescein, the time dependent change of its concentration in the corneal stroma and in the aqueous humor yields the transfer coefficient (Kc) of the corneal endothelium. Measurements with a fluorophotometer resulted in a Kc of 0.002 minute to 0.005 minute for normal eyes. Patients with corneal barrier dysfunction (cornea guttata, Fuchs dystrophy) showed an increased Kc of 0.006 minute to 0.013 minute. Up to five years postoperatively, none of the patients investigated after phacoemulsification and posterior chamber lens implantation showed a disturbance in the endothelial cell barrier function.
