It is well known that the three main factors that affect refractive performance in a toric IOL implantation are preoperative measurement,accurate alignment of the IOL and its stability in the bag[25].The accurate alignment of toric IOLs is crucial for the best possible postoperative refractive outcome and high patient satisfaction.However,for the best possible alignment,the consideration of the ocular cyclotorsion plays a pivotal role.A considerable number of studies were conducted in order to evaluate the accuracy of image-guided systems in toric IOL alignment and compare them with different conventional manual ink-marking techniques(Table 4).Among them,horizontal slit beam marking(HSBM)[34],subjective direct visual marking(SDVM)on the table(using a bevel knife tip)[34],marking with pendulum-attached marker[41]and withbubble marker instrument[26,28].For the assessment of imageguided systems in the alignment of toric IOLs,a variety of parameters were taken into consideration,including the mean toric IOL misalignment and rotation(the difference between the axis of the toric IOL 1h postoperatively and at consecutive follow-up timepoints)[26],the mean residual refractive cylinder,the mean uncorrected distance visual acuity(UDVA)as well as the BCDVA,the mean deviation from the target-induced astigmatism(TIA),and the mean overall time required for the alignment and for the whole cataract surgery.
