Induced astigmatism in a 6.0 mm no-stitch frown incision.
Fifty-five consecutive patients had cataract extraction with a 6 mm no-stitch frown incision and implantation of a 6 mm optic three-piece posterior chamber lens. Vector analysis calculations of diopters (D) of mean induced keratometric astigmatism for this incision were 0.70 D at one day, 0.76 D at one week, 0.50 D at one month, and 0.50 D at three months. The Naeser's polar value showed a mean with-the-rule astigmatism of +0.42 D at one day and -0.08 D against-the-rule astigmatism at three months. The results suggest that the 6.0 mm no-stitch frown incision induces a low postoperative astigmatism and provides a stable incision.
