Patients were divided into two groups \u2013 group A underwent phacoemulsification with OCCI and group B underwent phacoemulsification with toric IOL implantation. Uncorrected distance visual acuity (UDVA), manifest refractive cylinder, and corneal astigmatism using corneal tomography were measured preoperatively and at 6 weeks postoperatively. The eyes were categorized into three groups with PEA ranging from 1 to 1.5 D, 1.6 to 2 D, and 2.1 to 3 D. Depending upon the white-to-white corneal diameter, the eyes were also categorized into four groups with corneal diameter ranging from 10.5 to 10.9 mm, 11 to 11.4 mm, 11.5 to 11.9 mm, and 12 to 12.4 mm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Sixty eyes of 60 patients were studied. At postoperative 6 weeks, 83.3% (25 eyes) in the OCCI group and 96.7% (29 eyes) in the toric IOL group achieved UDVA of 6\/9 or better. No statistically significant difference was noted between the groups (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.37). The reduction in mean corneal astigmatism was 0.63 \u00b1 0.37 D in the OCCI group and 0.15 \u00b1 0.12 D in the toric IOL group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).
