Medications for a scratched cornea include topical nonsteroidal anti-inflammatory drugs such as diclofenac and ketorolac, states American Family Physician. Some doctors also prescribe topical antibiotics such as bacitracin or erythromicin ointments or chloramphenicol or gentamycin eyedrops.
NSAID eyedrops ease the pain associated with a scratched cornea, explains American Family Physician. Antibiotic ointments help prevent infection and are more soothing than drops, so doctors who prescribe antibiotics initially recommend these. For people who wear contact lenses, antibiotics that act on the bacteria Pseudomonas aeruginosa, such as ciprofloxacin, gentamycin and ofloxacin, are usually the best choice. Pseudomonas aeruginosa is a common bacteria that can cause serious infections of the eye if contact lenses aren't properly sterilized, notes WebMD.
Although standard treatment for a scratched cornea once included patching the eye, doctors no longer recommend this practice, advises American Family Physician. Studies show that patching does nothing to decrease the pain associated with a scratched cornea and actually causes more pain in some patients. Additionally, patching the eye often decreases oxygen delivery to the cornea and increases moisture in the eye, which increases the risk of infection.
