The ophthalmic literature of the past half century contains relatively few reports of true exfoliation of the lens capsule, reflecting a reduction in the occupation-related occurrence of "glassblower's cataract." The authors report 11 eyes (7 patients) with a diaphanous membrane arising from the anterior lens capsule, which they have identified by slit-lamp biomicroscopy. None of the seven patients had had extended exposure to an infrared-emitting heat source or ocular trauma; one patient with bilateral true exfoliation of the lens capsule had a history of unilateral herpes simplex keratitis. The average age of these patients at the time of diagnosis was 85.4 years. Identification of these 11 eyes by two ophthalmologists during a 6-year period suggests that idiopathic true exfoliation of the lens capsule has been underdetected, under-reported, or both.
