Introduction

The aim of the study was to evaluate the intraoperative complications during phacoemulsification of a posterior polar cataract, especially the risk of posterior capsule rupture.

Material and methods

The retrospective evaluation of complications during phacoemulsification of a posterior polar cataract in patients in the Department of Ophthalmology, Medical University of Warsaw from January 2001 to June 2007. The surgical procedures, as well as the implanted IOL type and intraoperative and postoperative complications were evaluated in every case in 2 years’ observations. Best-corrected visual acuity before and 3 months after surgery was evaluated using the standard Snellen chart.

Results

The study group consisted of 16 individuals, 6 women and 10 men in age 21-55 (mean 32.7). 22 eyes were operated on, all using the phacoemulsification method through corneal incision (10 individuals – 1 eye, 6 individuals – both eyes). In all cases, phacoemulsification was performed using a hydrodissection free technique by corneal incision. A posterior capsule rupture was observed in 4 eyes (18%), localized in the central region and caused by changes in the capsula. The mean visual acuity was significantly better after cataract surgery. The best corrected visual acuity (BCVA) was 6/6 in 8 eyes (36%). A BCVA of less than 1.0 was caused by either amblyopia or nystagmus.

Conclusions

Phacoemulsification in patients with posterior polar cataract is associated with a high risk of posterior capsule rupture and potential vitreous loss, which is why this procedure should be performed carefully by senior surgeons using an appropriate, hydrodissection free technique.
