Abstract

Recently, a training mannequin suitable for ophthalmic blocks has been developed. It provides a new feature of visual feedback to the trainee. A validation of the efficacy of this training system with needle angle visualization, ocular structure proximity, and procedural warning features was conducted in an evaluative study with 41 participants; 21 post graduate trainees and 20 ophthalmic consultants from a tertiary ophthalmic care facility in Chennai, India. The participant’s performance was evaluated and analyzed using an appropriate scoring scheme in two sessions with and without visual feedback. The participants were also requested to provide feedback on the anatomical likeness and usage. A two tailed signed rank Wilcoxon test verified the statistical significance of the visual feedback (Pz(4.55, 0.05)= 0.9999, $P\lt $0.001). The mean score of the participants showed an increase 58.86% and 25.5% for graduate trainee and consultants respectively and a mean reduction of 85.41% in the warning indications provided was also substantiated the efficacy of the visual feedback.

视觉反馈支持的眼角膜块训练模型:一项评估性研究

最近，一种适合眼块的训练模型被开发出来。它为受训者提供了视觉反馈的新功能。在一项有41名参与者的评估性研究中，对该训练系统的有效性进行了验证，包括针角可视化、眼结构接近性和程序性警告特征;来自印度金奈一家三级眼科护理机构的21名研究生受训人员和20名眼科顾问。在有和没有视觉反馈的两个阶段中，使用适当的评分方案评估和分析参与者的表现。参与者还被要求对解剖相似性和用法提供反馈。双尾符号秩Wilcoxon检验验证了视觉反馈的统计学显著性(Pz(4.55, 0.05)= 0.9999， $P\lt $0.001)。参与者的平均得分显示，毕业生培训生和咨询师分别提高了58.86%和25.5%，提供的警告指示平均降低了85.41%，也证实了视觉反馈的有效性。
