Which of the following should NOT be used in the treatment of a mechanical corneal abrasion?

• A. Artificial tears
• B. Topical cycloplegic
• C. Topical steroid
• D. Topical antibiotic

Answer: (C)

In a mechanical corneal abrasion, the goal is to promote healing of the epithelial defect, keep the ocular surface lubricated, relieve pain, and prevent infection. Lubrication with artificial tears helps the damaged surface stay moist, supporting epithelial migration. A topical cycloplegic can reduce painful ciliary spasm and photophobia, providing comfort while the surface heals. Prophylactic topical antibiotics are used to prevent infection because the protective barrier is compromised. Topical steroids, however, should not be used in simple corneal abrasions because they can slow epithelial healing and dampen local immune defenses, raising the risk of infection or delayed closure. They are reserved for inflammatory or different pathological conditions under careful supervision.
