We describe the use of a simple tool to evaluate the postoperative alignment of toric intraocular lenses (IOLs). The entire anterior segment is scanned using anterior segment optical coherence tomography and analyzed with an internal dedicated tool. A topographic map is displayed along with an anterior segment image, including a linear axis marker centered on the corneal apex. The marker can be rotated until it is aligned with the line connecting the IOL marking dots, precisely reproducing the IOL astigmatic axis, which is measured in angle degrees. The value of the IOL astigmatic axis is compared with the value of the astigmatic axis shown in real time on the same screen in the topographic map. Evaluating the alignment of a toric IOL axis simultaneously with the topographic astigmatic axis eliminates the potential errors that result from head tilting and strictly correlates with the astigmatic correction achieved.
我们描述了一种简单工具的使用方法，该工具可用于评估散光人工晶状体（IOL）的术后准度。使用前节光学相干断层扫描对整个前节进行扫描，并使用内部专用工具进行分析。显示一个地形图，并带有前节图像，包括一个以角膜顶点为中心的线性轴标记。可以旋转标记，直到其与连接 IOL 标记点的线对齐，精确复制 IOL 散光轴，该轴以角度度数测量。将 IOL 散光轴的角度值与地形图上同一屏幕上实时显示的散光轴的角度值进行比较。同时评估散光 IOL 轴与地形图散光轴的准度，可以消除因头部倾斜而导致的潜在误差，并且与实际实现的散光矫正严格相关。
