■在小切口微透镜摘除(SMILE)的初始学习曲线中,调查后平面意外初始解剖的潜在危险因素。
■数据来自在外科医生学习曲线开始时接受SMILE的136名患者的连续263只眼。分析了左眼和右眼后面意外初始解剖的可能性。术前球体,气缸,球形当量(SE),J0,J45,透镜状直径,透镜状厚度,角膜厚度,在无意进行后平面解剖的眼睛和无意进行后平面解剖的眼睛之间评估眼轴长度。
■29只眼意外初次解剖后平面,相当于11.03%的发病率。左眼平面解剖困难的概率明显高于右眼(P=0.003)。球体差异显著(T=2.8,P=0.006),SE(T=2.37,P=0.019),J0(T=2.05,P=0.043)和眼轴长度(T=-2.79,P=0.006)在有和没有意外初始解剖后平面的情况下。
■在本研究中,对于右手医生来说,SMILE期间的平面解剖困难在左眼中更常见,并且在具有低SE或高J0值的眼睛中。在这种情况下,应特别注意防止意外的后平面初始解剖。
UNASSIGNED: To investigate potential risk factors for unintended initial dissection of the posterior plane in the initial learning curve of small incision lenticule extraction (SMILE).
UNASSIGNED: Data were derived from consecutive 263 eyes of 136 patients who underwent SMILE at the beginning of the surgeon\'s learning curve. Probabilities of unintended initial dissection of the posterior plane in left and right eyes were analyzed. Preoperative sphere, cylinder, spherical equivalent (SE), J0, J45, lenticular diameter, lenticular thickness, corneal thickness, and axial length were assessed between eyes in which posterior plane dissection was unintended and those in which it was not.
UNASSIGNED: Unintended initial dissection of the posterior plane occurred in 29 eyes, corresponding to an incidence rate of 11.03%. The probability of difficulty in plane dissection in the left eye was significantly higher than that in the right eye (P=0.003). Significant differences were found in sphere (T =2.8, P=0.006), SE (T =2.37, P=0.019), J0 (T =2.05, P=0.043) and axial length (T =-2.79, P=0.006) between eyes with and without unintended initial dissection of the posterior plane.
UNASSIGNED: In the present study, difficulty in plane dissection during SMILE was encountered significantly more often in left eyes for a right-hand doctor, and in eyes with low SE or high J0 values. Special attention should be paid to prevent unintended initial dissection of the posterior plane in such situations.
