Advanced instrumentation and intraocular lenses (IOL) allow great refractive and visual outcome control to permit excellent correction of refractive aberrations. Residual astigmatism can be modified to provide depth of focus using an appropriate incision in the steepest meridian in manual small-incision cataract surgery (MSICS). The authors describe the nomogram for surgically correcting astigmatism (SCA). This technique can handle preoperative astigmatism of about 2.25 DCyl with the standard incisions—straight incision of 5, 6, and 7 mm in length, the minimally curved frown incision, the frown incision, the frown incision with an accentuated frown, and the U incision placed on the steep axis in the superior or the temporal quadrant depending on the axis of pre-operative astigmatism.
