Purpose

The authors present the advantages of intraoperative digital visualization with a 3D system in case of posttraumatic cataract surgery.

Setting

"Agostino Gemelli" University Polyclinic Foundation, Rome, Italy

Methods

A 40-year-old male patient referred to our attention for bulbar trauma at work in the left eye with scarring outcomes due to supertemporal paralimbar accidental corneal perforation, transparent central cornea, and posttraumatic white cataract with irido-phacodonesis. Preoperative bulbar ultrasound scans demonstrated absence of endobulbar foreign body and plane retina in all sectors. The preoperative UCVA was equal to light perception in all the quadrants.

Results

The surgical approach was to prepare for any eventuality, planning firstly a standard phacoemulsification technique with a tensioning ring insert and subsequent in the bag IOL implantation, but preparing at the same time the surgical field in advance for pars plana vitrectomy (PPV) and implantation of a scleral fixation IOL if necessary to complete the intervention. During the facoemulsification of the hard cataract nucleous a subtotal dislocation of the capsular bag occured. Then, a PPV was performed with removal of the residual cortex and the entire dislocated capsular bag, and a Carlevale scleral fixation IOL implantation using the same PPV sclerotomies with a personal technique was performed to complete the surgery.

Conclusions

The opportunity of using an intraoperative 3D digital visualization system has made it possible to perform the surgery with greater versatility in the passages between the anterior and posterior segment, with an optimal visualization of the entire operating field for the surgeon and the entire OR team, at all levels, minimizing the changes in focus and magnification, and also reducing the time of exposure to light of the eye tissues. Moreover, this technology permits to show and teach to the residents the approach and the surgery solutions in very complex surgery cases.
