Image quality was quantitatively evaluated using signal-to-noise ratio, distinction between retinal layer image intensity distributions, and retinal layer segmentation performance. Measures were compared pre- and postoperatively across different degrees of averaging. <jats:italic>Results.<\/jats:italic> 13 eyes of 13 patients were included and 1092 layer boundaries analyzed. Preoperatively, increasing image averaging led to a logarithmic growth in all image quality measures up to 96 frames. Postoperatively, increasing averaging beyond 16 images resulted in a plateau without further benefits to image quality. Averaging 16 frames postoperatively provided comparable image quality to 96 frames preoperatively. <jats:italic>Conclusion.<\/jats:italic> In patients with clear media, averaging 16 images provided optimal signal quality. A further increase in averaging was only beneficial in the eyes with senile cataract. However, prolonged acquisition time and possible loss of details have to be taken into account.<\/jats:p>","DOI":"10.1155\/2017\/8148047","type":"journal-article","created":{"date-parts":[[2017,5,23]],"date-time":"2017-05-23T17:24:44Z","timestamp":1495560284000},"page":"1-8","source":"Crossref","is-referenced-by-count":9,"title":["Impact
