Eyes having undergone multiple surgeries or blind eyes may develop deposition of calcium on the corneal surface. This intern results in chronic irritation, watering and photophobia. It also increases the risk o developing a corneal infection. A simple and effective technique for removal is by the use of a chemical compound called EDTA (Ethylenediaminetetraacetic acid), which when applied on the corneal surface for about 30-60 secs, chelates and removes the calcium deposits. This inturn helps reduce symptoms and is may also help benefit patients in gaining usable vision in the treated eye (if the eye has visual potential). The procedure is simple and cost effective and provides consistent results when done properly.
