Purpose: To evaluate the use of 23 gauge pars plana vitrectomy in management of droppednucleus after phacoemulsification by two different techniques according to dropped nucleus sizeand consistency. Patients and Methods: Thirty eyes of thirty patients with dropped nucleusduring phacoemulsification divided into two groups; each group consists of fifteen eyes. Group A includes 15 eyes performed using transconjunctival sutureless 23 gauge pars planavitrectomy system with the use of PFCL and full removal of all dropped nuclear fragment by thevitreous cutter .Group B includes 15 eyes performed using transconjunctival suture less 23gauge pars plana vitrectomy system with the use of PFCL and removal of some droppednuclear fragment by the vitreous cutter while the others were removed through a limbal incisionor scleral frown. Results: In group A we found that the mean VA was improved from 0.3preoperatively to 0.3, 0.7 and 0.7 at 1st week, 3rdand 6 months postoperatively respectively. Ingroup B we found that the mean VA was improved from 0.2 preoperatively to 1st week, 3rd and6 months postoperatively respectively. In group A we found that the mean IOP was changedfrom 16 mmHg at the baseline to 19 mmHg, 17 mmHg and 16 mmHg at1st week, 3rd and 6months postoperatively respectively. In group B we found that the mean IOP was changed from18 mmHg at the baseline to 17 mmHg, 18 mmHg and 16 mmHg at 1st week, 3rd and 6 monthspostoperatively respectively. Conclusion: Twenty three gauge pars plana vitrectomy wassuccessful in cases of dropped fragments or quadrants and being soft cataract, while if it was allof the nucleus we can minimize its size by the vitreous cutter, and removing the remaining partsthrough a limbal wound or scleral frown trying to preserve the sutureless procedure as possible.
