Abstract

Purpose: To investigate the performance of 10 MHz ultrasonography in detecting posterior lens capsule defects before traumatic cataract surgery.

Methods: This retrospective analysis includes patients with traumatic cataracts who underwent cataract surgery. Preoperative 10 MHz ultrasonography was performed to evaluate whether the posterior lens capsule was defective or intact, and the results were compared to the intraoperative findings. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and kappa were calculated.

Results: The study included 140 eyes of 140 patients. There were 68 eyes with closed-globe injuries and 72 eyes with open-globe injuries. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and kappa of 10 MHz ultrasonography was 86.76%, 90.28%, 89.39%, 87.84%, 88.57% and 0.771, respectively. The accuracy was 86.11% and 91.18% in open-globe and closed-globe injury groups, respectively.

Conclusion: The accuracy of 10 MHz ultrasonography in evaluating the posterior lens capsule in traumatic cataracts is high. Preoperative 10 MHz ultrasonography would help to make an appropriate surgical plan.

Conflict of interest statement

Declarations. Ethical approval: All procedures performed in studies involving human participants were in accordance with the ethical standards of the Institutional Review Board of Joint Shantou International Eye Center (JSIEC), Shantou University and the Chinese University of Hong Kong and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. Informed consent: Informed consent was exempted in the study because it is a retrospective analysis and the data was anonymized. Conflicts of interest: All authors certify that they have no affiliations with or involvement in any organization or entity with any financial interest (such as honoraria; educational grants; participation in speakers’ bureaus; membership, employment, consultancies, stock ownership, or other equity interest; and expert testimony or patent-licensing arrangements), or non-financial interest (such as personal or professional relationships, affiliations, knowledge or beliefs) in the subject matter or materials discussed in this manuscript.
