UNLABELLED: To characterize the differences in technique, complications, and outcomes in a large series of cataract extractions in patients with and without pseudoexfoliation (PEX) syndrome.
SETTING: Ophthalmic Consultants of Boston, Boston, Massachusetts, USA.
METHODS: A retrospective analysis was performed of 297 cases of cataract extraction in patients with PEX and 427 cases of cataract extraction in patients without PEX. This study examined and quantified the intraoperative and postoperative complications, performed a comparative outcomes analysis of intraocular pressure (IOP) change, and determined the prevalence of systemic vascular diseases in these patients.
RESULTS: The overall rate of vitreous loss was 4% (7/297) in the PEX population and 0% (0/427) in the non-PEX group. There were no overall differences in the rate of postoperative complications. At 2 years, IOP had declined from a mean of 16.8 to 13.9 mm Hg in the PEX group and from 16.3 to 14.4 mm Hg in the non-PEX group. The decline was significantly greater in the PEX group. The prevalence of hypertension and diabetes was significantly greater in the non-PEX group (50% and 11%, respectively) than in the PEX group (38% and 5%, respectively).
CONCLUSIONS: The increased frequency of intraoperative complications during cataract extraction in PEX patients stemmed from zonular weakness rather than capsule tears. Postoperative IOP declines were greater in the PEX group even 2 years after cataract extraction, suggesting the potential for long-term improvement in outflow facility in patients with coexisting cataract and glaucoma.
