Corneal Transplantation

The cornea is largely subdivided into epithelium, strom, and endothelium. Depending on the degree of invasion of the cloudy lesion, it is classified into full-thickness keratoplasty, in which the entire cornea is transplanted, and lamellar keratoplasty, in which only a portion of the cornea is transplanted.

The most common corneal transplant surgery A surgical method in which all three layers of the cornea, the epithelium, stroma and endothelium, are transplanted at once

A method of separating the patient's corneal stroma from the Descemet's membrane using the big bubble technique, cutting out only the front part including the epithelium of the cornea from the donor cornea, and transplanting it to the recipient.

Used to treat diseases affecting the front surface of the cornea, such as keratoconus

A method of removing the degraded endothelial cell layer in a patient with corneal disease due to decreased endothelial cell function, and transplanting a part of the posterior stroma, Descemet's membrane, and endothelial cells obtained from the donor cornea using a microkeratectomy or femtosecond laser.

Used to treat diseases such as Hookes' corneal dystrophy, posterior polymorphic keratosis, bullous keratopathy

A method of exfoliating Descemet's membrane and endothelial cells from the donor cornea to replace the Descemet's membrane and endothelial cells in the donor cornea.

Used to treat diseases such as Hookes' corneal dystrophy, posterior polymorphic keratosis, bullous keratopathy
