NCT02155270

Brief Summary

We would like to evaluate the use of a 600μm pre-cut regarding wound architecture and surgically induced astigmatism as compared to a stab-incision (a corneal incision without a pre-cut). A dedicated wound architecture score will be used to evaluate wound configuration. Postoperatively, OCT scans will be obtained, corneal curvature will be measured and subjective and objective refraction will be performed in order to measure the surgically-induced astigmatism.
