Traumatic cataracts do not always involve rupture of the posterior capsule membrane. A traumatic cataract is a clouding of the lens caused by blunt contusion, perforation, or blast injuries to the eye. A clouding of the lens prevents light from refracting into the interior of the eye, which can lead to vision loss. Rupture of the posterior lens capsule is usually not seen if the trauma is not severe and does not involve the posterior lens capsule. For example, some traumatic injuries only result in the lens being squeezed, which can cause it to become cloudy but the posterior capsule is still intact, whereas other traumatic injuries can result in the anterior lens capsule being ruptured but the posterior capsule membrane is not damaged. Severe blunt contusions and perforating injuries to the eyeball can cause the posterior capsule membrane to rupture. When the lens capsule membrane is extensively injured, it is accompanied by significant inflammation of the anterior segment of the eye or secondary glaucoma in addition to visual impairment. It is recommended that patients go to the hospital in time to improve the relevant examination and follow the doctor’s instructions for treatment.
