To compare the efficiency and safety of steep-axis one-handed phacoemulsification with steep-axis two-handed phacoemulsification.<jats:italic>Patients and Methods<\/jats:italic>. Patients with cataracts underwent steep-axis one-handed (steep-axis one-handed group) or steep-axis two-handed (steep-axis two-handed group) phacoemulsification with a 2.4\u2009mm clear corneal incision (CCI) under the guidance of the Verion Image-Guided System. Intraoperative phacoparameters, such as visual acuity, surgically induced astigmatism (SIA), total corneal astigmatism (TCA), angle of error (AE), corneal volume (CV), and corneal endothelial cells, were compared.<jats:italic>Results<\/jats:italic>. There were no significant differences in the intraoperative phacoparameters between the two groups. The visual outcomes were significantly better in the steep-axis one-handed group than in the two-handed group at 1\u2009week postoperatively (all<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn>0.05<\/mml:mn><\/mml:mrow><\/mml:math>) but not at 1\u2009month and 3\u2009months postoperatively. TCAs were significantly decreased in both groups at 1 and 3\u2009months postoperatively (all<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn>0.05<\/mml:mn><\/mml:mrow><\/mml:math>).

At 3\u2009months postoperatively, the SIA was 0.95\u2009\u00b1\u20090.44\u2009D in the steep-axis one-handed group and 1.01\u2009\u00b1\u20090.50\u2009D in the steep-axis two-handed group; there was no significant difference between the groups. The AE was 39.45\u2009\u00b1\u200926.53\u00b0 in the steep-axis one-handed group and 49.75\u00b0\u2009\u00b1\u200926.23\u00b0 in the steep-axis two-handed group, which were significantly different (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.005<\/mml:mn><\/mml:mrow><\/mml:math>). Endothelial cell loss was significantly lower in the steep-axis one-handed group than that in the steep-axis two-handed group at all follow-up points (all<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M5\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn>0.05<\/mml:mn><\/mml:mrow><\/mml:math>).<jats:italic>Conclusions<\/jats:italic>. Both the steep-axis one-handed and the steep-axis two-handed techniques could significantly decrease TCA. Compared with the steep-axis two-handed technique, the steep-axis one-handed technique has the advantage of decreasing the AE and reducing trauma to the cornea in soft-to-moderate nuclei.<\/jats:p>","DOI":"10.1155\/2019\/7182324","type":"journal-article","created":{"date-parts":[[2019,9,15]],"date-time":"2019-09-15T19:31:07Z","timestamp":1568575867000},"page":"1-7","source":"Crossref","is-referenced-by-count":2,"title":["Clinical
