SANTACRUZ, I  e  CIBILS, D. Posterior capsule rupture in cataract surgery: frequency, management and visual result. Mem. Inst. Investig. Cienc. Salud [online]. 2011, vol.9, n.1, pp. 43-48. ISSN 1812-9528.

To determine the frequency of the posterior capsule rupture (PCR) during cataract surgery, the intra and post-operatory management and the final visual acuity (VA) an observational retrospective study was carried out with the records of patients subjected to cataract surgery in our service from April 2007 to March 2008. Demographic data, pathological records, pre and postoperative VA, alterations of the fundus of the eye, surgical technique, experience of the surgeon, vitreous loss during the surgery, vitrectomy type, implant of intraocular lenses, postoperative complications. Seven hundred fifty four patients were subjected to cataract surgery during the study period, 54 (7.1%) presented PCR. Records of 49 patients with PCR were selected for the variable analysis. Mean age was 69 years old, 38 patients (76%) had preoperative AV of count fingers to light perception, 10 patients (20.4%) presented pupil dilation lower than 6 mm, 19 (38.8%) showed capsular pseudoexfoliation and 73.5% were operated by residents. Extracapsular extraction was made in 79.6% of the cases. The 73.5% presented vitreous loss and were subjected to vitrectomy, 69.4% received implant of intraocular lenses and 26.5% presented post-operatory complications. The 75.5% of the patients achieved a post-operatory VA better than 20/140. A statistically significant relation was found when the post-operatory VA was compared with the presence of complications (p: 0.01). The PCR is a complication to which all cataract surgeons are exposed to and the adequate management is essential to avoid complications as much as possible and achieve good VA.
