Indications for cone corneal surgery include cloudy corneas caused by cone corneas, tumors, and so on. Cone corneal surgery involves cutting out the diseased cornea and replacing the diseased cornea with clear, normal corneal tissue. The more common types of corneal clouding are caused by corneal leukoplakia, inflammation, cone cornea, and tumors. Lamellar corneal transplants include epiretinal stem cell transplants, deep lamellar transplants, and corneal endothelial transplants. If the entire corneal layer is not involved, a lamellar corneal transplant can be used to treat conical corneas on the advice of your doctor. If the entire layer is involved, even the posterior elastic layer can rupture. Scars after rupture can also be repaired with a partial penetrating corneal graft, but not all scars are conical corneas. Conical cornea is a relatively less invasive, relatively safe and effective procedure that can prevent the progression of conical cornea.
