Thanks for your question.
Your cat has most likely scratched the conjunctiva
causing a conjunctival abrasion. This layer of tissue covers the sclera (the tough white outer coating of the eye).Omnipred
is a steroid
. It will not prevent infection. It is important that you see an eye doctor to rule out any deeper injury
. The doctor may decide to stitch the conjunctiva back into place if it is a large defect. He/she is also likely to prescribe you an antibiotic ointment which will help prevent infection while the abrasion heals.
