Abstract
Purpose :
To compare the efficacy between 23-gauge sutureless pars plana vitrectomy (PPV) and anterior vitrectomy in the management of vitreous loss associated with posterior capsular rupture (PCR) during cataract surgery.
Methods :
Medical records of 139 eyes which sustained PCR and vitreal prolapse to anterior chamber during cataract surgery were retrospectively reviewed. Thirty two eyes which underwent 23-gauge sutureless pars plana vitrectomy (group PPV) and 107 eyes which underwent anterior vitrectomy (group AntV) were compared in postoperative visual and anatomic outcomes, operation time, and complications.
Results :
No significant differences were found between the groups in final best-corrected visual acuity of 20/40 or better (AntV vs. PPV = 80.4% vs. 90.6%, P=0.139). However, the visual recovery rates (20/40 or better) 1 day, 1 week, 1 month postoperatively were significantly higher in group PPV (antV vs PPV = 22.4 % vs. 44%, 32.2 vs 58.6 %, 51.9 vs. 78.1%)). Postoperative IOP-related complications requiring medication were less evident in group PPV (antV vs. PPV = 52.3 % vs. 6.3%, P<0.001). Twelve cases (11.2%) of group AntV and 0 cases of group PPV underwent secondary operation during follow-up. While no postoperative complications occurred in group PPV, complications—such as endophthalmitis, retinal detachment, cystoid macular edema , IOL instability –were observed in the AntV group (none vs. 14%, p= 0.022 ).
Conclusions :
23-gauge sutureless PPV is a safe and reliable solution for managing vitreous loss during cataract surgery. Therefore, it is expected to be considered primarily in institutes with vitreoretinal surgeons.
