Abstract Details


To evaluate complications and outcomes of B-MICS performed by a surgeon in training.


Institute of Ophthalmology, University of Modena & Reggio Emilia, Modena, Italy.


A prospective study regarding the first 42 eyes of 38 patients who underwent cataract surgery performed by the same surgeon in training, using for the first time B-MICS, under supervision by expert surgeon. Intra- and postoperative complications and intraoperative parameters were recorded. Preoperative and postoperative parameters evaluated were visual acuity, astigmatism, corneal pachymetry and endothelial cell count.


Of the 42 cataract surgery cases, 5 were iris trauma (11.9%), one of these (2.38%) with postoperative iris prolapse; 2 of capsule rupture without vitreous loss (4.76%); 2 of posterior capsule rupture with vitreous loss (4.76%); 1 of IOL implantation in the sulcus owing to marked zonular laxity (2.38%); 1 IOL loop malposition (2.38%). After surgery, visual acuity improved at 7 and at 30 days. There was a statistically significant endothelial cell loss between the pre- and postoperative stages, at 7 and at 30 days from surgery. There was no statistically significant difference between pre- and postoperative astigmatism, either at 7 or at 30 days. Instead, we recorded a higher mean astigmatism after surgery in complicated cases (vitreous loss, capsular tear or capsular weakness) as compared with the preoperative values.


Complication rates are similar to those reported in the literature on cataract surgery performed by a surgeon in training with traditional phacoemulsification technique. B-MICS is a good and safe technique, also when performed by a surgeon in training and it can be considered as easy to learn or, at least, of no greater difficulty than the traditional coaxial technique.
