A cornea biopsy is the removal and testing of a very small sample of corneal tissue. It is most often used when there has been a lack of response to treatment so your doctors can have a better idea of the health of your eye and can better diagnose a variety of infections and troublesome conditions.
This is a very minor procedure; the corneal biopsy will be performed while at the slit-lamp or operating microscope. Using topical anesthesia, a small piece of corneal tissue is removed and sent to the laboratory for additional testing. The amount of removed tissue will be superficial and only about one-millimeter in diameter, so it will have no effect on your vision.
The corneal biopsy can be a very helpful tool to get a more in-depth look into the health of your eyes. It is a minimally invasive procedure that is done with topical anesthesia right in our office, and we will keep you extremely comfortable throughout the process. Even though a biopsy is a procedure that has its own risks, think of it as a means to make sure that you know exactly what is going on in your eye.
