To investigate whether individuals with long-term reduced stereopsis were able to obtain the same level of surgical skills in simulated vitreoretinal surgery on the Eyesi Surgical Simulator as individuals with normal stereopsis.
Twenty-four medical students were recruited and divided into two groups according to their degree of stereopsis: Group 1 (n = 12) included subjects with normal stereopsis (60 arcsec or lower) and Group 2 (n = 12) included subjects with reduced stereopsis (120 arcsec or higher). Stereopsis was tested using the TNO test (Lameris Ootech BV, Nieuwegein, the Netherlands). The participants were trained in virtual reality-simulated vitreoretinal surgery and continuously measured using a test with solid validity evidence and a pre-defined pass-fail score. All data were analysed using the Wilcoxon rank sum test.
We observed no differences in overall performance scores for any of the four modules. The participants with reduced stereopsis used 5.8 more attempts in bimanual training (p = 0.04), 8.8 more attempts in removal of posterior hyaloid (p = 0.04), 9.1 more attempts in navigation training (p = 0.20) and 0.3 fewer attempts in removal of internal limiting membrane (p = 0.69).
The final performance scores on the Eyesi Surgical Simulator were independent of the degree of stereopsis. However, the number of attempts to achieve the pre-defined pass-fail score increased significantly with reduced stereopsis in two of four modules. These results indicate that a high degree of stereopsis is not necessary to become proficient in microsurgery but may prolong the learning curve.
研究长期立体视减退的个体在Eysi手术模拟器上进行模拟玻璃体视网膜手术时，是否能获得与立体视正常的个体相同水平的手术技能。
招募24名医学生，根据他们的立体视程度分为两组：第1组（n = 12）包括立体视正常（60角秒或更低）的受试者，第2组（n = 12）包括立体视减退（120角秒或更高）的受试者。使用TNO测试（荷兰尼乌韦根的Lameris Ootech BV公司）检测立体视。参与者在虚拟现实模拟玻璃体视网膜手术中接受培训，并使用具有确凿有效性证据和预先定义的通过/失败分数的测试进行持续测量。所有数据均使用Wilcoxon秩和检验进行分析。
我们观察到四个模块中任何一个的总体表现得分均无差异。立体视减退的参与者在双手操作训练中多尝试了5.8次（p = 0.04），在切除后玻璃体膜中多尝试了8.8次（p = 0.04），在导航训练中多尝试了9.1次（p = 0.20），在切除内界膜中少尝试了0.3次（p = 0.69）。
Eysi手术模拟器上的最终表现得分与立体视程度无关。然而，在四个模块中的两个模块中，随着立体视减退，达到预先定义的通过/失败分数所需的尝试次数显著增加。这些结果表明，要熟练掌握显微手术，并不一定需要高度的立体视，但可能会延长学习曲线。
