The Correct Option is C
Solution and Explanation
Concept:
INTACS are intracorneal ring segments used to flatten and regularize the cornea. They are mainly used in keratoconus, especially when contact lens intolerance or irregular astigmatism is present.
Step 1: Identify the device.
INTACS are small semicircular intracorneal ring segments placed within the corneal stroma.
Step 2: Understand the effect.
They help flatten the steep cornea and reduce irregular astigmatism.
Step 3: Connect with disease.
Keratoconus is characterized by progressive corneal thinning and conical protrusion. INTACS are used to improve corneal shape in such patients. Therefore, the correct answer is Keratoconus.
