Sample itemWhy should a contact lens be removed in suspected corneal infection when feasible?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. It may harbour organisms and obstruct assessment
Removing the lens permits corneal examination and culture when needed and reduces ongoing microbial reservoir in suspected contact-lens-related keratitis.
Option by option
A. It may harbour organisms and obstruct assessment (correct)
Correct: lens can retain pathogens and mask cornea.
B. It permanently protects against ulceration
Lenses increase rather than prevent keratitis risk.
C. It improves fluorescein interpretation
Fluorescein can be assessed after removal.
D. It treats pain by itself
Removal alone does not treat infection.
