Journal of Cataract & Refractive Surgery: July 1994 - Volume 20 - Issue 4 - p 406-409 doi: 10.1016/S0886-3350(13)80175-7 Free Metrics Abstract 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. © Williams & Wilkins 1994. All Rights Reserved.
