All patients received a 2.2\u2010mm self\u2010sealing scleral incision (<jats:italic>n<\/jats:italic>\u00a0=\u00a024), single\u2010plane clear corneal incision (<jats:styled-content style=\"fixed-case\">SPCCI<\/jats:styled-content>;<jats:italic> n<\/jats:italic>\u00a0=\u00a029) or biplanar clear corneal incision (<jats:styled-content style=\"fixed-case\">BPCCI<\/jats:styled-content>;<jats:italic> n<\/jats:italic>\u00a0=\u00a024). Measurements of anterior and posterior corneal astigmatism were performed with a rotating Scheimpflug camera (Pentacam <jats:styled-content style=\"fixed-case\">HR<\/jats:styled-content>) preoperatively and postoperatively. Two repeated readings were taken preoperatively to assess the role of the test\u2013retest effect.

Scleral incisions on average did not cause AC, although steepening, flattening or torque beyond the test\u2013retest effect was observed in individual cases. On the posterior surface, mean power changes in the incisional meridian were below 0.1\u00a0D for all incisions, and these changes were of the same order of magnitude as the test\u2013retest effect.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Surgically induced AC of the posterior corneal surface after cataract surgery is of negligible clinical relevance.
