A corneal transplant is advised to patients who have corneal scarring or thinning. A research study from the Netherlands found transplantation led to improved vision and stabilization of the disease in most of their participants. It also determined that placing the donor tissue in the middle of the cornea helps in faster healing period.
There are also several kinds of corneal transplant surgery recommended for patients suffering from keratoconus, such as lamellar keratoplasty. This is a partial-thickness procedure in which only a section of the cornea is replaced. Penetrating keratoplasty is a full transplant and removes the full thickness of the cornea and replaces it with donor tissue. Lastly, deep anterior lamellar keratoplasty involves preserving the endothelium of the cornea and is useful for a successful transplant, as the surgery helps avoid transplant rejection by preserving a critical inside lining in the cornea.
