Penetrating Keratoplasty

Penetrating Keratoplasty, commonly referred to as corneal transplant surgery or grafting, is a surgical procedure used in ophthalmology to replace a damaged or diseased cornea with a healthy one from a donor. The cornea is the clear outermost layer of the eye, which is responsible for refracting light onto the retina. There are several indications for corneal transplantation, such as keratoconus, corneal dystrophy, corneal scarring from injury, corneal ulcers, and other degenerative diseases. The procedure involves removing the entire cornea and replacing it with donor tissue that has been screened and tested for compatibility. Penetrating Keratoplasty is performed under local or general anesthesia and takes between one and two hours to complete. The surgery involves creating an incision in the cornea, removing the damaged tissue, and sizing and placing the donor corneal tissue into the opening. The new cornea is then secured to the eye using sutures, which are removed after a few weeks. Postoperatively, the patient is prescribed antibiotic and anti-inflammatory drops and will be advised to avoid strenuous activities and rubbing the eye. Recovery time varies, but most people can return to normal activities within a month. It may take up to a year for the vision to fully stabilize. Penetrating Keratoplasty has a high success rate and is known to restore vision in many cases where other treatments have failed. This procedure is a life-changing solution for those who suffer from vision loss due to corneal disease, injury, or degeneration.
