Mature cataract and lens-induced glaucoma associated with an asymptomatic intralenticular foreign body.

We report a case of mature cataract and lens-induced glaucoma associated with an asymptomatic intralenticular foreign body. At initial presentation, the patient had no definite history of ocular trauma. During cataract surgery, a metallic intralenticular foreign body was expressed with hydrodissection and easily removed with intraocular forceps. Postoperative visual acuity, ocular status, and electroretinographic findings indicated that the crystalline lens served as a natural barrier to irreversible intraocular toxicity.
