Microincision cataract surgery (MICS) is an approach to cataract surgery through incision less than 1.8 mm with the purpose of reducing surgical invasiveness, improving at the same time surgical outcomes. The main confirmed advantages of MICS are the control and avoidance of surgically induced corneal astigmatism and the decrease of postoperative corneal aberrations. MICS has been demonstrated to be minimally traumatic surgery, providing better postoperative outcomes than standard small incision phacoemulsification.
Today, surgery is performed through 1 mm incision. The use of the modern MICS intraocular lens (IOL) requires incisions of 1.8 mm. The increased availability of MICS IOLs allows to select the best IOL as per the demand of the patient.
