The ophthalmologist and the grapes: A microsurgical training model

Abstract Objective: Develop a training model for corneal surgery using grapes. Methods: Grapes were used as structures that mimic the size of the human eyeball, covered with latex materials, simulating the practice of corneal surgery using a videomagnification system. Eight simple stitches were performed. The surgical time was evaluated. Results: 25 simulations were carried out as the model described. The mean time taken for the raffia was 34.56 ± 5.79 minutes. The analysis of the correlation between the time and the order of the surgeries showed a reduction in the confection time. Conclusion: The ophthalmic training model using grapes proved to be capable of simulating the basic stages of microsurgery suture training.

摘要
研究目标：开发一款以葡萄为模拟载体的角膜手术（corneal surgery）训练模型。
研究方法：选取葡萄作为模拟人类眼球尺寸的结构体，覆以乳胶材料（latex materials），搭配视频放大系统（videomagnification system）开展角膜手术模拟练习，完成8次简单缝合操作，并对手术时长进行评估。
研究结果：按该模型共开展25次模拟训练，单次缝合操作的平均时长为34.56±5.79分钟。对手术时长与操作顺序的相关性分析显示，手术时长呈逐步缩短趋势。
研究结论：以葡萄构建的眼科训练模型可有效模拟显微手术缝合（microsurgery suture）训练的基础流程。
