What are the different types of keratoplasty surgery?
The cornea is a pure tissue covering the front of the eye and if it becomes abnormal due to the disease or damage, corneal transplantation may be required. The surgery of keratoplasty is performed in which the cornea tissue from the donor is used to replace the unhealthy areas of the patient's cornea. Depending on the type of condition that the patient has, different methods of keratoplasty surgery may be used. Options include penetration keratoplasty, where the whole cornea is replaced, and endothelial keratoplasty, which replaces the inner corneal lining. There is no transplant in conductive keratoplasty, but surgery is used to change the shape of the cornea to correct problems such as penetration. Swelling and scarring destroys the clarity of the cornea, which makes it difficult to pass light. The distorted shape means that any light on the cornea is not normally focused.
The disease known as keratoconus can cause a thinning cornea, which gradually protrudes forward and creates the shape of the cone. Sometimes the cornea after a few weeks onOne swollen, leading to the development of scars. If damage is serious, keratoplasty penetration surgery may be performed.
During penetrating keratoplasty surgery, the entire cornea of the patient is removed by means of a circular cut before a circle of the donated cornea is stitched. The operation takes about two hours and does not need to require overnight stay in the hospital. After several months, the stitches are removed gradually, during the year or more.
Endothelial keratoplasty surgery is usually performed when diseases such as endothelial fuchs dystrophy affect cells that form an inner lining or endothelium. Fuchs's endotheldystrophy IAL causes endothelial cells that normally remove the corneal fluid, and the result of the corneal and turbidity swelling. During the endothelial keratoplasty surgery, a small cut is made in the eye to remove the patient of the endothelium. They are inserted in its placedonated endothelial cells. If the operation is successful, the eye function can improve relatively quickly, in about six weeks.
conductive surgery of keratoplasty does not include corneal transplantation. Instead, the shape of the cornea changes to be less flat to improve its ability to focus on the retina light. The procedure uses energy from radio waves to reduce the outer circle of corneal tissue, causing the center to curl more steeply. Patients recover quickly and usually improve vision in about a week.
