What is a lens laceration?

A lens laceration is the disruption of the transparent membrane that surrounds the lens, termed the lens capsule.  Lens lacerations are always associated of a traumatic puncture of the eye.

What causes a lens laceration?

Lens lacerations are always a result of a penetrating trauma of the eye, usually coupled with a corneal laceration or puncture.  Cat scratches to the eye are the most common presentations.

Why are lens lacerations important?

If the disruption fo the lens capsule is large enough, it will result in a massive inflammatory reaction within the eye that leads to painful, non-visual globe.  This reaction takes time to develop and may not become apparent until 2 weeks after the initial traumatic incident.

What is the treatment for a lens laceration?

The treatment for a lens laceration is the surgical removal of the lens in a process known as phacoemulsification.  This advanced procedure allows for the complete removal of the lens and, if the lens capsule is sufficiently intact, placement of an artificial lens that will result in the return of normal vision.  A lens laceration is considered an emergency and should be addressed immediately.
