. Purpose: To assess long‐term positioning of posterior chamber intraocular lenses within the capsular bag in eyes with pseudoexfoliation syndrome. Methods: The study includes 44 patients with pseudoexfoliation syndrome and 85 age‐matched controls, who underwent cataract surgery in 2001 and 2002 at the Eye Department, Oslo University Hospital. In 2008, all patients were re‐examined. A comparison of the extent of possible decentration in eyes with and without pseudoexfoliation syndrome was made by evaluating Scheimpflug images (Pentacam) of the anterior segment. Results: It was found that, 6–7 years following cataract surgery, posterior chamber intraocular lenses were positioned lower in eyes with pseudoexfoliation syndrome than in control eyes. The difference was statistically significant (p = 0.01). Downward shift was associated with presence of glaucoma only in eyes with pseudoexfoliation syndrome (p = 0.01). No patients had visual disturbances related to displacement of the intraocular lens. Three of the patients with pseudoexfoliation syndrome (6.8%) had observable pseudophacodonesis by slit‐lamp examination, compared to one in the control group (1.2%). The study demonstrated that Pentacam is an appropriate instrument to measure decentration of intraocular lenses. Conclusion: The study suggests that, 6–7 years after cataract surgery, the intraocular lenses within the capsular bag are more prone to decentration in pseudoexfoliation syndrome eyes, compared to controls.
