Impact of B-Scan Averaging on Spectralis Optical Coherence Tomography Image Quality before and after Cataract Surgery

Figure 4

Intraindividual evaluation of quantitative measures of image quality for all 13 patients. On the x-axis, the number of averaged frames preoperatively is shown, which is needed to achieve the same result as an average of 16 frames postoperatively. A 16-frame scan provides the most beneficial setting after cataract surgery. Comparison is computed individually for each patient. On the y-axis, the number of cases is shown. “None” indicates that there was no averaging setting preoperatively, which achieved the same result as postoperatively.
