Abstract

Abstract: : Purpose: Ultrasound biomicroscopy and high frequency ultrasound (HFU) (20 MHz) allows in vivo imaging of anterior segment structures, including zonules, at microscopic resolution. The purpose of this prospective study was to evaluate the ability of HFU to detect preoperatively zonular abnormalities and correlate it with intraoperative complications during cataract extraction surgery of these eyes. Methods: 109 eyes of 109 patients with cataract were evaluated using HFU (I3 - Innovative Imaging Inc.) during a day prior to cataract surgery. Radial images were taken through the lens, zonular bundles (anterior and posterior) and the ciliary body. Ultrasound signs of zonular abnormalities were evaluated (missing zonules or zonular stretch). Results: Of 109 eyes, 25 were found to have zonular abnormalities, and 84 eyes were found normal (detected by HFU). 10 of the 25 eyes (40%) with zonular abnormalities did have intraoperative complications. Only 9 of the 84 "normal" eyes (11%) did have intraoperative complications (P=0.002). Conclusion: We found a higher rate of intraoperative complications in eyes in which zonular abnormalities were detected preoperatively by HFU than in eyes that were suggested as normal by HFU. HFU can be used as an additive tool in the preoperative evaluation of eyes before cataract surgery.
