CORNEAL GRAFT Meaning and
Definition
-
A corneal graft, also known as corneal transplantation or keratoplasty, is a surgical procedure that involves replacing a damaged or diseased cornea with a healthy corneal tissue obtained from a deceased donor. The cornea is the clear, dome-shaped front surface of the eye that covers the iris and pupil, responsible for focusing light onto the retina.
A corneal graft aims to restore or improve vision by addressing a range of conditions that affect the cornea, including corneal scarring, thinning, infections, or distortion. The procedure usually involves removing the damaged portion of the cornea and replacing it with a carefully selected corneal graft that matches the patient's eye size and shape. The graft can be taken from a tissue bank or, in some cases, from a living donor.
The corneal graft procedure is typically performed under local or general anesthesia in an operating room. During the surgery, the surgeon places the donor cornea onto the patient's eye and stitches it securely in place. Over time, the patient's own tissue will grow into the donor tissue, integrating it into the eye.
Post-operative care involves the use of medications, including antibiotics and anti-rejection drugs, to prevent infection and rejection of the graft. Regular follow-up visits are essential to monitor the healing process and ensure optimal visual outcomes.
Corneal grafts have demonstrated significant success rates in restoring vision and improving quality of life for individuals with corneal disorders, making it an invaluable procedure within the field of ophthalmology.

Etymology of CORNEAL GRAFT

2. Graft:
The term "graft" comes from the Old English word "græft", which means "fitting" or "joining together". It can be traced back to the Proto-Germanic word "graftiz", meaning "to dig".
