Cornea
The cornea is a dome-shaped, clear, outermost lens of the eye which covers the anterior chamber, iris and pupil.
It functions as a convex lens & along with the intraocular lens helps to focus light on the retina and forms a clear image.
The cornea is responsible for almost 60% of our vision. Corneal transplant surgery involves surgical removal of the unhealthy cornea (either total or partial) and replacing it with a healthy, transparent donor cornea (complete or partial). A cornea transplant surgery is also known as keratoplasty.
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye’s total optical power. Various disorders affecting the cornea can lead to pain, irritation, reduced vision, and sometimes blindness.
The latest techniques in Corneal Transplantation like Lamellar Keratoplasty (Deep Anterior Lamellar Keratoplasty and Endothelial Keratoplasty) are performed with good quality tissues. In patients not suitable for these procedures penetrating keratoplasty can be done. Instruments available Keratometer, Corneal topographer, Specular microscope.
