Purpose To evaluate changes in anterior corneal topography after femtosecond laser-created clear corneal incisions (CCIs). Setting Fondazione G.B. Bietti IRCCS, Rome, Italy. Design Comparative case series. Methods Phacoemulsification was performed through a 2.75 mm incision. In the study group, a 3-plane CCI was created using a 150 kHz femtosecond laser. In the control group, a single-plane angled CCI was created using disposable knives. Placido disk corneal topography was performed preoperatively and 1 week and 1 month postoperatively. Central curvature (simulated keratometry [K]) and local changes in anterior corneal topography at the CCI site were evaluated and compared between groups. Results No significant changes in the mean simulated K values were found in either group postoperatively (P >.05). The preoperative to 1-month postoperative mean simulated K ranged between 43.30 diopters (D) ± 0.82 (SD) and 43.17 ± 0.82 D in the study group and between 43.34 ± 1.44 D and 43.29 ± 1.48 D in the control group. The method of CCI creation significantly influenced the changes in the anterior central topography during the first month postoperatively (P
