title: The evaluation of patients with traumatic cataracts by ultrasound technologies.
abstract: Surgery for traumatic cataracts is a potentially complex procedure. Clinically, traumatic cataracts may be difficult to thoroughly assess due to the presence of other significant ocular damage including corneal scars, posterior synechiae, and vitreous hemorrhage. Frequently, surgery involves surprises regarding the integrity of the posterior capsule and zonular structure. Careful ophthalmic imaging using ultrasound technologies may result in finer pre-operative detail regarding lens support structures, and may therefore give the surgeon the advantage when planning surgery. Imaging techniques most applicable to pre-operative evaluation include B scan ultrasound, 20MHz ultrasound, and ultrasound biomicroscopy. Important modifications to technique that can be made depending on the integrity of lens support structures include adjustment of wound location, adjustment in the technique for cataract removal, and possible use of a capsular tension ring.
