Traumatic cataract

Cataract formation is commonly observed as a result of direct penetration of the crystalline lens by a foreign object or by blunt trauma to the globe or adnexa, creating a "shock wave" within the eye. Partial or total damage to the zonules may also occur, resulting in subluxation or total displacement of the crystalline lens. The primary care doctor of optometry plays an important role in evaluating patients with cataract, both immediately and long after the injury has occurred. Many of these patients can be managed conservatively by careful observation, while others will require surgical intervention.
