Congenital Cataract
The presence of cataract in the newborn child is called congenital cataract. Mostly, cataract surgeries are performed in infants to prevent blindness, but it is mostly dependent on the location and opacification of the cataract.
Classification of cataract based on the causative agent.
Traumatic cataract:
Cataracts formed due to a trauma is called traumatic cataract. Cataracts can be formed even after a long time has passed. These cataracts either have a star or a rose like shape.
Radiation cataract:
Cataract formed when the eye is highly exposed to radiations such as X-rays or Gamma rays is called radiation cataract. These cataracts are mostly located in the posterior portion of the lens.
Secondary cataract:
The cloudiness in the posterior capsule of the eye is called secondary cataract. 30% of people undergo the treatment for secondary cataract after the cataract removal.
Morgagnian cataract:
A Morgagnian cataract is the hyper- mature cortical cataract. At the beginning of the cortical cataract, spoke-like shapes starts to appear in the eyes because of the degeneration of the proteins in the eyes.
Post-vitrectomy cataract:
During this surgery, the surgeon removes the vitreous gel from the eye and replace it with another fluid. After some time, the liquids start to break down and dissolve more oxygen, which leads to nuclear cataract.
