**Core Concept**
Vernal keratoconjunctivitis (VKC) is a bilateral, chronic, and recurring inflammatory eye disease characterized by intense itching, photophobia, and tearing. It predominantly affects children and young adults, with a higher prevalence in males. The pathophysiology of VKC involves a complex interplay between environmental factors, such as pollen and dust, and immunological responses.

**Why the Correct Answer is Right**
The treatment of VKC involves a multi-faceted approach, including topical corticosteroids to reduce inflammation, mast cell stabilizers to prevent mediator release, and immunomodulatory agents to modulate the immune response. Topical corticosteroids, such as loteprednol and rimexolone, are effective in reducing symptoms and inflammation. Mast cell stabilizers, such as cromolyn and lodoxamide, prevent the release of histamine and other mediators, thereby alleviating symptoms. Immunomodulatory agents, such as cyclosporine, may be used in severe cases to modulate the immune response.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not provide a valid treatment for VKC. However, without the correct answer, I can only provide a general explanation.

**Option B:** This option is incorrect because it is a treatment for VKC, but the specific medication is not as commonly used as others.

**Option C:** This option is incorrect because it is a treatment for VKC, but the specific medication is not as commonly used as others.

**Option D:** This option is incorrect because it is not a treatment for VKC.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that VKC often requires a combination of treatments to effectively manage symptoms and prevent recurrence. It is essential to identify and avoid environmental triggers, such as pollen and dust, to prevent exacerbation of symptoms.

**Correct Answer:** D.
