How do you use EDTA for band keratopathy?

As previously mentioned, 0.05 mol, 1.5% neutral disodium EDTA can be applied to the corneal surface to aid in superficial debridement for band keratopathy. Weck-cel sponges soaked in this solution can be used for this purpose, or the solution can be placed in a water bath over the cornea to limit ocular exposure.

How do you remove a band keratopathy?

Superficial debridement is the least invasive surgical management for band keratopathy and can be conducted in clinic. To remove the deposits, the affected areas are scraped with a beaver blade and then treated with sponge or filter paper soaked in 3% ethylenediaminetetraacetic acid (EDTA).

What is EDTA chelation eye surgery?

Studies have reported EDTA chelation to be a safe, reliable method of removing band keratopathy, resulting in improvements in visual acuity and ocular comfort. 1, 2. This procedure can be used in isolation or supplemented with superficial keratectomy (manual or excimer laser PTK) or amniotic membrane transplant.

What is EDTA used for in the eye?

Eye drops containing EDTA are used to treat calcium deposits in the eye. In foods, EDTA bound to iron is used to “fortify” grain-based products such as breakfast cereals and cereal bars. EDTA is also used to help preserve food; and to promote the color, texture, and flavor of food.

How do you make EDTA eye drops?

EDTA is prepared as a 3 % solution by diluting disodium EDTA 15 % (150 mg/ml) 1:4 with normal saline. A drop of topical anesthetic is instilled into the eye at the beginning of the procedure. Epithelial debridement is performed with a surgical blade.

How do you get rid of calcium in the cornea?

The most common methods for removing the calcium deposits are mechanical debridement with a blade, chemical chelation with ethylenediaminetetraacetic acid (EDTA), and phototherapeutic keratectomy. Manual debridement of CBK by scraping with a blade is effective but can lead to an irregular corneal surface.

How long does it take for EDTA to work?

Injected intravenously and once in the bloodstream, EDTA traps lead and other metals, forming a compound that the body can eliminate in the urine. The process generally takes 1 to 3 hours.

What is a melting eye?

Corneal melting is a common prelude to the development of corneal perforation. This process occurs from conditions such as infections, sterile inflammation, or surgical/chemical injury to the cornea. 1, 2, 3. Collectively, these conditions are a significant cause for blindness world-wide.

Is EDTA chelation safe?

Chelating agents can also have serious, even life-threatening side effects. One of the most serious side effects of EDTA is kidney damage and kidney failure. Other side effects that have been reported in patients taking some forms of EDTA have included: Anemia.

Can Keratopathy be cured?

Over time, the inflammation can spread deeper into your cornea and eye. There’s no cure, but you can often control it with antiviral drugs or steroid eyedrops.
