Performing pars plana vitrectomy to remove retained post-phacoemulsification lens fragments shows good visual outcomes and a low incidence of complications regardless of the timing of surgery, according to a retrospective study conducted by researchers in the United Kingdom.

Shu Fen Ho, MRCOphth, and Anwar Zaman, FRCOphth, of Queens Medical Centre, Nottingham, reviewed outcomes for 82 eyes of 82 patients. All cases underwent pars plana vitrectomy (PPV) to remove lens fragments left behind after phacoemulsification cataract surgery.

The researchers found that 46.3% of patients experienced an increase in IOP. However, eyes that underwent anterior vitrectomy had a significantly lower incidence of elevated IOP (P = .006), the authors reported.

"There was no association between late vitrectomy and a worse visual outcome," they noted.

Complications occurred in 4.9% of cases and included retinal detachment and cystoid macular edema. No patients developed endophthalmitis, according to the study published in the December issue of the Journal of Cataract & Refractive Surgery.
