**Core Concept**
Congenital ptosis is a condition where there is a drooping of the upper eyelid present at birth, which can lead to amblyopia if not treated promptly. The goal of surgical intervention is to lift the eyelid to improve vision and prevent amblyopia. Surgical procedures for ptosis aim to improve eyelid function and appearance.

**Why the Correct Answer is Right**
Since the question asks for the operation NOT used in ptosis, we must consider the common surgical procedures for ptosis, such as levator aponeurosis advancement, Müller's muscle conjunctival resection, and frontalis sling suspension.

**Why Each Wrong Option is Incorrect**
**Option A:** Could be a valid procedure, depending on the specifics of the case.
**Option B:** Might also be applicable in certain situations.
**Option C:** Could potentially be used, based on the individual patient's needs.

**Clinical Pearl / High-Yield Fact**
Early intervention in congenital ptosis is crucial to prevent amblyopia, and the choice of surgical procedure depends on the severity of the ptosis and the levator function.
