Manual small incision cataract surgery SICS is very versatile surgery as it is easily modifiable, needs minimal instruments, no equipment dependence, can be performed quickly and at very low cost. The technique can be further simplified by constructing a limbo-corneal tunnel with controlled stab incision obliquely at the posterior limbus without superior rectus stitch, conjunctival flap or cautery. It reduces the overall surgical time to 9-12 minutes by eliminating many avoidable surgical steps and related complications. The technique has the advantages of both the approaches (scleral tunnel for SICS and corneal pocket for phaco) with comparable induced astigmatism than superior incision and better AC manipulations. Limbal incisions heal faster and resist more deformation pressure than cornea. The technique is comfortable to perform and visual outcome is equally good.
