What steps should be taken if a patient reports vision flashes or contact lens-induced corneal staining?

• A. Stop wear, inspect lens for damage, assess cornea, schedule follow-up, consider alternate lens options.
• B. Increase wear time to acclimate to symptoms.
• C. Ignore and continue wear.
• D. Only treat with antibiotic drops without examining lens or cornea.

Answer: (A)

Vision flashes or contact lens–induced corneal staining signal potential corneal stress or injury from the lens. The most important first move is to stop wearing the lenses to prevent further damage. Next, inspect the lens for damage. Look for scratches, chips, nicks, or warpage. Damaged lenses can cause ongoing irritation and staining, so replacing or rechecking the fit is essential. Then assess the cornea. Examine for epithelial defects with fluorescein staining and check for signs of irritation, dryness, or edema. A careful corneal check helps determine how severe the reaction is and whether urgent treatment or closer follow-up is needed. Arrange a follow-up promptly to monitor healing and adjust management based on the response. If symptoms worsen or there are signs of a more serious issue (such as a corneal ulcer), escalate care quickly or refer for professional evaluation. Consider alternate lens options. This may involve trying a lens with higher oxygen permeability, adjusting the fit (base curve, edge design), or switching to a different modality (for example, daily disposables) to reduce risk of recurrence and improve comfort and safety. These steps protect the cornea from further injury, help identify the cause (lens damage, poor fit, or deposits), and ensure the patient can wear contact lenses safely in the future.
