Hi. We have had a case recently where a rust ring was removed

Customer Question

Hi. We have had a case recently where a rust ring was removed from a patients eye by a licenced physician. My question is about time line. Is there any 'rule of thumb' that allows us to determine how long it takes for a rust ring to develop?
He had reported an irritation to his eye approx 4pm and the rust ring was visible at 7pm.

Many thanks

Hello and thanks for your question. There's no rule of thumb that guides an ophthalmologist about when to expect to see a rust ring. They will usually appear fairly quickly, but because they are essentially part and parcel of most metallic corneal foreign bodies, and the rust rings usually are successfully and expeditiously removed, it usually is not much of a concern of ours. Does that make sense?
