: To evaluate the outcome and surgery-associated risks in patients undergoing 23-gauge pars plana vitrectomy (PPV) for retained lens fragments.
: Retrospective analysis of 42 eyes of 42 consecutive patients at a tertiary teaching hospital in Sydney (Australia) during a period of 4 years. Evaluation of final visual acuity, complications, differences in patients receiving an intraocular lens at the primary cataract surgery, and differences in final visual acuity regarding the usage of a phacofragmatome and analysis of pars plana vitrectomy-related complications.
: The majority (83.3%) achieved a visual acuity of 0.3 (logarithm of the minimum angle of resolution) or better, and 19 eyes (45.2%) achieved a final visual acuity of 0 (logarithm of the minimum angle of resolution). Overall, 95.2% of the eyes had a better postoperative visual acuity compared with the preoperative visual acuity. There were no differences in proportions regarding the final visual acuity in patients who had an intraocular lens at the time of the pars plana vitrectomy and those who had a secondary lens implant. A retinal detachment after the lens fragment removal was observed in 2 eyes.
: Dropped lens fragments because of complicated cataract surgery can be managed well with 23-gauge pars plana vitrectomy: The majority of patients achieve a good visual acuity despite 2 surgeries at a rather low rate of retinal complications.

    ABSTRACT: Posterior capsular rupture (PCR) is an infrequent complication of cataract surgery that can lead to significant ocular morbidity and permanent vision loss. In the setting of PCR, the primary objective is the safe and thorough evacuation of vitreous and lens fragments from the anterior segment. The secondary objective is the stable placement of an intraocular lens (IOL) selected for best refractive outcomes. Expedited referral to vitreoretinal specialists is recommended for management of posteriorly dislocated lens material and surveillance for retinal injury. It is the intention of this review to present current guidelines for the management of PCR. There are new techniques available to anterior and posterior segment surgeons in the setting of PCR. Endoillumination may facilitate visualization during anterior vitrectomy and the IOL may be used as a pupillary barrier to prevent loss of lens fragments. When secondary procedures are needed, early return to the operating room and small-gauge pars plana techniques may reduce patient morbidity. When approached carefully and systematically, patients may have good outcomes in the setting of PCR. Recent advancements in instrumentation and technique encourage further study and may lead to new standards of care.

    ABSTRACT: To demonstrate the feasibility of a sleeveless phacotip-assisted approach to levitate dropped nucleus. This single-centre, retrospective, interventional, non-comparative case series reviewed the medical records of 34 eyes of 34 patients. Corrected and uncorrected distance visual acuity (CDVA, UDVA), early and late postoperative complications and ultrasound biomicroscopic (UBM) evaluation of the sclerotomy site was analysed. At 18 months follow-up, the mean postoperative UDVA and CDVA in Snellen's decimal equivalent was 0.42±0.16 and 0.91±0.2, respectively. There was a significant improvement in the UDVA (p=0.001) and CDVA (p=0.002). Nucleus drop occurred following intraoperative posterior capsular rupture in 25 eyes (73.5%), zonular weakness in 5 eyes (14.8%) and post-trauma in 4 eyes (11.7%). In the early postoperative period, corneal oedema was seen in 2 eyes, pigment dispersion in 3 eyes and vitritis in 2 eyes. There was loss of CDVA in 1 (2.9%) eye due to persistent cystoid macular oedema. UBM did not reveal any vitreous incarceration into the sclerotomy site. Dropped nucleus was successfully levitated into anterior chamber with this technique, resulting in a significant visual outcome with a favourable complication rate.
