**Complicated Cataract: Core Concept**
Complicated cataract is a type of cataract that develops as a result of intraocular inflammation, trauma, or other ocular diseases. It is characterized by posterior subcapsular cataract formation, often with a zonular dialysis or retinal detachment.

**Why the Correct Answer is Right**
Complicated cataract typically presents with symptoms such as decreased visual acuity, glare, and double vision. This is due to the formation of a posterior subcapsular cataract, which can cause light to scatter and affect vision. The inflammation or trauma that leads to complicated cataract can also cause damage to the zonular fibers, leading to a zonular dialysis. This can cause the lens to become dislocated or subluxed, further complicating the condition.

**Clinical Pearl / High-Yield Fact**
