Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.
Was your eye doctor an optometrist or an ophthalmologist?
What you are talking about is very common and is called a Hudson-Stahli line. It is usually located on the lower third of the cornea, is limited to the epithelial layer and noticed in patients 50 or so years old.
It is not a sign of any sort of pathology or problem and requires no treatment.
It has nothing to do with your current or future vision and will not impact your previous LASIK surgery.
So what is the take home message? I would not give these iron deposits another thought. They are of no consequence. I'm sorry that your eye doc did not explain this to you.
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me.
