Technology allows accurate detection of secondary cataracts

After cataract surgery a troubling number of patients develop posterior capsule opacity, also known as a “secondary cataract,” whereby a cloudy membrane develops behind the newly implanted lens.  Recognizing this condition normally requires expert analysis, and while automated systems exist that detect lens opacity, they are not looking for creeping growth of cells onto the new lens.

Researchers at University of Alicante in Spain have now developed fully automatic software that provides a proper diagnosis of posterior capsule opacity from magnified images of the ocular fundus.  The researchers claim this is a highly accurate system that detects the growing cells that infect the implanted intraocular lenses.
