[Ultrasound biomicroscopy in evaluation of conditions for secondary intraocular lens implantation in aphakia].

In order to evaluate conditions for secondary intraocular lens (IOL) implantation detailed analysis of ultrasound biomicroscopy (UBM) images of 26 patients (33 eyes) with aphakia was performed. The etiology of cataract was congenital (12 eyes), traumatic (9 eyes), senile (8 eyes) and uveal (4 eyes). The results showed that UBM provides an opportunity to evaluate the implantation site considering capsule integrity, configuration and parameters of ciliary line. The authors have demonstrated that UBM is scarcely the only visualization method in aphakic eyes that lets find and evaluate structural changes of the globe, induced by trauma, uveitis or improper lens removing during cataract surgery (iridocapsular or iridocorneal synechiae, iris defects, pupillar membranes, lens remnants, vitreoretinal proliferation and others). The authors propose UBM to be included into diagnostic examination of patients with aphakia before secondary IOL implantation and consider the results of UBM in choice of lens model and type of fixation.
