Ultrasound biomicroscopic study of anterior segment changes after phacoemulsification and intraocular lens implantation

ABSTRACT

To study the changes in anterior segment configuration after phacoemulsification and intraocular lens implantation by means of ultrasound biomicroscopy [UBM]. Fifteen eyes of 15 patients with senile on presnile cataract and no other illness were participate in this work. All patients were examined with UBM before and one month after surgery. At each UBM examination, central anterior chamber depth [ACD1], depth from the cornea to the pupillary plane [ACD2], angle opening distance at 500 micron from scleral spur [AOD500] and trabecular iris angle [TIA] were recorded. Central anterior chamber depth increased after surgery as well angle opening distance and trabecular iris angle at 500u from scleral spur. After phacoemulsification, UBM revealed that deepening of the anterior chamber and widening of its angle occurred. This finding may be of clinical importance in patients with closed angle glaucoma
