Abstract
Purpose: To demonstrate the safety and outcome of a surgical approach that uses pars plicata site for
anterior vitrectomy during phacoemulsification procedure complicated by posterior capsule rupture
and residual cortical matter. Design: Single center, retrospective, interventional, noncomparative study.
Materials and Methods: Medical records of a consecutive series of 35 eyes of 35 patients who underwent
pars plicata anterior vitrectomy (PPAV) were reviewed. The main outcome measures were corrected
and uncorrected distance visual acuity (CDVA, UDVA), early and late postoperative complications and
intraocular pressure (IOP). Ultrasound biomicroscopic (UBM) evaluation of sclerotomy site and spectral
domain optical coherence tomography analysis for central macular thickness (CMT) was performed.
The final visual outcome at 2 years was evaluated. Results: At 2 years follow‑up, the mean postoperative
UDVA (logarithm of the minimum angle of resolution [logMAR]) and CDVA (logMAR) was 0.49 ± 0.26
and 0.19 ± 0.14, respectively. There was no significant change in the IOP (P = 0.061) and the mean CMT at
2 years was 192.5 ± 5.54 μm. The postoperative UBM image of the sclerotomy site at 8 weeks demonstrated
a clear wound without any vitreous adhesion or incarceration. Intraoperative hyphema was seen in 1 (2.8%)
case and postoperative uveitis was seen in 2 (5.7%) cases, which resolved with medications. No case of an
iatrogenic retinal break or retinal detachment was reported. Conclusions: PPAV enables a closed chamber
approach, allows thorough cleanup of vitreous in the pupillary plane and anterior chamber and affords
better access to the subincisional and retropupillary cortical remnant with a significant visual outcome and
an acceptable complication rate.
