Pseudoexfoliation (PEX) of the lens capsule is a well-known risk factor for open-angle glaucoma. Its prevalence is known to increase by age in the same way as prevalence of age-dependent cataract. In the present paper the prevalence of PEX varied from 8.5 to 13.2% increasing by age. Lens opacities were statistically significantly more common in PEX-positive than PEX-negative eyes. The importance of detecting exfoliation from the lens surface is discussed.
