Traumatic cataracts occur secondary to blunt or penetrating ocular trauma. Lens dislocation and subluxation are found commonly in conjunction with traumatic cataract.
Traumatic cataract can present many medical and surgical challenges to the ophthalmologist.
Careful examination and a management plan can simplify these difficult cases and provide the best possible outcome. Blunt trauma is responsible for coup and contrecoup ocular injury. Coup is the mechanism of direct impact. Contrecoup refers to distant injury caused by shockwaves traveling along the line of concussion. When the anterior surface of the eye is struck bluntly, there is a rapid anterior-posterior shortening accompanied by equatorial expansion.
