After corneal foreign body removal, what is commonly placed to promote healing?

• A. A bandage lens
• B. A scleral contact lens
• C. A patch
• D. No treatment

Answer: (A)

Healing after a corneal foreign body is removed is aided by protecting the corneal surface so epithelial cells can migrate smoothly and pain is reduced. A bandage contact lens is commonly placed for this purpose. It acts as a cushion over the cornea, minimizing friction from blinking, maintaining a moist surface, and providing a stable, smooth platform for epithelial cells to move across and cover the defect. This protection helps accelerate healing and lowers pain by shielding exposed nerves. In practice, it’s used alongside appropriate topical antibiotics and close follow-up to watch for infection or lens-related issues. The lens should be fitted by a clinician and removed or replaced once the epithelial defect has healed or if signs of complication arise. Other options don’t promote healing as effectively in the typical immediate post-removal scenario. A patch can impede tear exchange and oxygen delivery to the cornea and carries risks of infection; a scleral lens is larger and reserved for larger or irregular defects rather than the common short-term post‑removal healing of a focal corneal abrasion; opting for no treatment would leave the surface exposed and slow healing.
