About Keratoplasty

Keratoplasty refers to a cornea transplant technique that is considered as the most sought after way to restore vision when the inner cell layer of the cornea stops working properly from Fuchs’ dystrophy, bullous keratopathy, iridocorneal endothelial (ICE) syndrome, or other endothelial disorders. This procedure selectively replaces only the diseased layer of the cornea, leaving healthy areas intact.

There are two major types of corneal transplants: traditional, full thickness cornea transplant (also known as penetrating keratoplasty, or PK) and back layer cornea transplant (also known as endothelial keratoplasty, or EK).

A graft replaces central corneal tissue, injured because of disease or eye injury, with strong corneal tissue donated from a local eye bank. A morbid cornea hampers your vision by scattering or distorting light and leading to glare and blurred vision. A cornea transplant may become imperative to restore your functional vision.

Corneal eye disease is the fourth most common cause of blindness (after cataracts, glaucoma and age-related macular degeneration) and affects more than 10 million people worldwide.*

Need of A Cornea Transplant

A healthy, clear cornea is extremely necessary for clear vision. If the cornea gets damaged due to eye disease or eye injury, it can get swollen, scarred or severely misshapen and mislead your vision.

A corneal transplant might get necessary in cases of conditions such as trichiasis, where eyelashes turn inward and rub against the surface of the eye, causing scarring and vision loss. A cornea transplant may be necessary if eyeglasses or contact lenses can't regain your functional vision, or if painful swelling can't be relieved by medications or special contact lenses.

Certain conditions can hamper the clarity of your cornea and put you at higher risk of corneal failure. These include:

  • Scarring from infections, such as eye herpes or fungal keratitis.
  • Scarring from trichiasis, when eyelashes grow inwardly, toward the eye, and rub against the cornea.
  • Hereditary conditions such as Fuchs' dystrophy.
  • Eye diseases such as advanced keratoconus.
  • Thinning of the cornea and irregular corneal shape (such as with keratoconus).
  • Rare complications from LASIK surgery.
  • Chemical burns of the cornea or damage from an eye injury.
  • Excessive swelling (edema) of the cornea.
  • Graft rejection following a previous corneal transplant.
  • Corneal failure due to cataract surgery complications.

The Procedure

Conventional corneal transplant surgery - During traditional corneal transplant surgery, or penetrating keratoplasty (PK), a circular button-shaped, full-thickness section of tissue is eliminated from the diseased or injured cornea using either a surgical cutting instrument called a trephine or a femtosecond laser.

A matching "button" from the donor tissue is then placed and sutured into place. The sutures (stitches) remain in place generally for a year or more after surgery.

Eventually, a plastic shield is placed over your eye to protect it during healing.

Penetrating keratoplasty surgery typically takes one to two hours and most procedures are carried out on an outpatient basis, meaning you can go home a short while after the surgery (though you will need someone to drive you home).

Endothelial keratoplasty - In the past decade, a latest version of corneal transplant surgery known as endothelial keratoplasty (EK) has been introduced for specific corneal conditions.

Endothelial keratoplasty selectively replaces only the innermost layer of the cornea (endothelium) and leaves the overlying healthy corneal tissue intact. The endothelium controls the fluid balance in the cornea, and if it becomes damaged or diseased, this can cause significant corneal swelling and loss of vision.

In EK, the surgeon creates a tiny incision and puts a thin disc of donor tissue featuring a healthy endothelial cell layer on the back surface of your cornea. An air bubble is meant to position the new endothelial layer into place. The small incision is self-sealing and typically no sutures are required.

Endothelial keratoplasty has various benefits over conventional full-thickness penetrating keratoplasty. These include: quicker recovery of vision; reduced operating time; minimal elimination of corneal tissue (and therefore less impact on the structural integrity of the eye and less susceptibility to injury); no associated suture complications; and lesser risk of astigmatism after surgery.

With the improvement of vision, you gradually will be able to return to your generally daily activities. For the first several weeks, heavy exercise and lifting are restricted. However, you should be able to return to work within a week after surgery, depending on your job and how quickly your vision improves.
