Randomized Controlled Trial Comparative StudyEffect of steepest-meridian clear corneal incision for reducing preexisting corneal astigmatism using a meridian-marking method or surgeon's intuition.
To compare the effect of steepest-meridian clear corneal incisions (CCIs) for reducing preexisting corneal astigmatism between a meridian-marking method and a surgeon's-intuition method. ⋯ The physical meridian misalignment of steepest-meridian CCI was significantly smaller with the meridian-marking method than with the surgeon's-intuition method; however, the effect of the difference was not large enough to decrease remaining astigmatism and HOAs or to improve the UDVA.
