After the development of non-astigmatic cataract surgery, a new generation
of intraocular lenses, able to manage previously existing corneal astigmatism, has
experienced a great expansion. Different choices for the surgeon include the possibility
of correcting simultaneously presbyopia, special designs for sulcus implantations and
customized dioptric powers. The keys to success when implanting these IOLs are
correct power calculation and correct surgical management with pre-surgical marking of
the cylindrical axis and ensuring correct alignment at the end of the procedure.
