Traumatic cataract is clouding of the lens and eyes that may occur after either blunt or penetrating ocular trauma that disrupts and damages the lens fibers. Most of the traumatic cataracts lead to eye lens swelling, but the type and clinical course depends on trauma and the integrity of the capsular bag. Traumatic cataracts occur in 24% of patients with globe contusions across the globe.
A concussion cataract may occur due to and in a blunt trauma. The lens capsule is not extensively damaged but becomes progressively opaque over a period of time. The traumatic cataract pathophysiology is the direct rupture and distortion of capsule or coup, equatorial expansion due to various forces transferring the energy effect of trauma to the other side of the eye.
Associated with Traumatic Cataract
It is essential to avoid eye injuries and eye trauma by taking appropriate measures. The most important thing is to use protective eyewear, including glasses and eye shields, to prevent eye injuries in hazardous situations at work and play, not spending too much time under the influence of infrared rays, ultra violet rays etc.
There are two questions with respect to the surgery of traumatic cataract: Should primary or secondary cataract surgery be performed, and what is the most proper and safe technique if the surgery is needed? Conservative management with lens preservation is followed to take care and look after accommodative potential in young patients unless there is significant vision loss or complications. In eyes with existing injuries, if the lens damage is clear and extensive with cortical material in the anterior chamber, lens removal is performed at the same time as repair of the cut in the cornea, termed as the primary procedure. The secondary procedure is the method in which the corneal laceration repair is performed initially, followed by cataractous lens removal with proper time intervals. Book an appointment now.
