**Core Concept**
The development of a shallow anterior chamber with corneal edema and secondary glaucoma is a known complication of cataract surgery. This condition is often caused by the blockage of aqueous humor outflow due to iris or lens material.

**Why the Correct Answer is Right**
The correct answer is related to the development of **phacolytic glaucoma**. Phacolytic glaucoma occurs when lens material, such as a cataract, blocks the trabecular meshwork and prevents the aqueous humor from draining properly. This leads to an increase in intraocular pressure (IOP), causing corneal edema and secondary glaucoma. The condition is more common in patients with mature or hypermature cataracts.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not describe a known complication of cataract surgery. **Option B:** This option is incorrect because it refers to a different condition altogether. **Option D:** This option is incorrect because it is not a direct complication of cataract surgery.

**Clinical Pearl / High-Yield Fact**
Phacolytic glaucoma is a medical emergency that requires immediate treatment to prevent vision loss. It is essential to recognize the signs and symptoms of this condition in patients who have undergone cataract surgery to ensure timely intervention.

**Correct Answer:** C.
