Abstract

INTRODUCTION:

Pseudoexfoliation (PXM) is a fibrillar material deposited in the anterior chamber of the eye and can cause disintegration of zonules and make pupillary dilatation difficult. This can make surgery difficult and result in intraoperative and postoperative complications. The aim of this study was to learn about whether the presence of pseudoexfoliation caused significant complications during cataract surgery.

MATERIALS AND METHODS:

We did a secondary data analysis of 12,992 eyes from 2007 to 2014 using the National Eye Database of Melaka Hospital Malaysia on intraoperative and postoperative cataract surgery complications of patients with PXM.

RESULTS:

Patients with PXM were 2.68 times more likely to get intraoperative complications (P < 0.001). They had a higher incidence of lens subluxation, zonular dehiscence, and vitreous loss (P < 0.001). Although posterior capsule rupture (PCR) was the most common intraoperative complication during cataract surgery (4.8%), the presence of pseudoexfoliation was not associated with PCR (P > 0.05). We did not observe any association between patients with pseudoexfoliation and any of the postoperative complications such as corneal decompensation, raised intraocular pressure, and intraocular lens decentration (P > 0.05). Pseudoexfoliation did not cause corneal decompensation (P > 0.05) although corneal decompensation was the highest postoperative complication of cataract surgeries (0.18%).

CONCLUSIONS:

Patients with PXM had a higher rate of intraoperative complications which were mainly vitreous loss and zonular dehiscence and also lens subluxation/dislocation. We observed poorer visual outcomes in those with PXM following cataract surgery. Patients with pseudoexfoliation should be identified and precautions taken to minimize these complications to get better visual outcomes.
