The external layer of the eye is called Cornea. It is one of the fundamental components of the human eye. As it allows the light to enter into the eye for one to have a clear vision. A cornea is usually 11mm in height and 12mm in length. The cornea further provides about 70 % of the focusing power of the eye. That is the principal reason why it is necessary to take care of the corneas.
Myopia, hyperopia, and astigmatism are Refractive problems. They are produced due to a change in the shape of the cornea.

WHEN DO YOU NEED A CORNEA SURGERY?
A healthy, clear cornea is important for good vision. If your cornea is damaged due to eye disease or eye injury, it can become swollen, scarred, or misshapen and distort your vision.
A corneal surgery might be required 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 surgery may be required if eyeglasses or contact lenses cannot improve your functional vision, or if painful swelling can’t be relieved by medications or special contact lenses.
Few problems may affect your cornea and put you at a 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.
- Flatting of the cornea and irregular corneal shape
- Rare complications from LASIK surgery.
- 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.
HOW YOU PREPARE
Before cornea transplant surgery, you will undergo:
A thorough eye exam. Your eye doctor looks for conditions that may lead to complications post-surgery.
Measurements of your eye. Your eye doctor decides what size donor cornea you require.
A review of all medications and supplements you’re taking. You might need to stop taking certain medications or supplements pre or post your cornea transplant.
Treatment for other eye problems. Unrelated eye problems, such as infection or swelling, may decrease your chances of a successful cornea transplant. Your eye doctor will work on those conditions before your surgery.
WHAT CAN YOU EXPECT
During the procedure
On the day of your surgery, you’ll be given a sedative to help you relax and a local anesthetic to numb your eye. You will not be asleep during the surgery but you should not feel any pain.
During the most frequent type of cornea transplant surgery (penetrating keratoplasty), a cut is made through the entire thickness of the cornea to remove a small disk of corneal tissue. An instrument called a trephine is used to make this small circular cut.
The donor cornea is then placed in the opening. Your surgeon then uses a thin thread to stitch the new cornea into place.
After the procedure
Post your cornea transplant, you can expect to:
Receive several medications. Eyedrops and, sometimes, oral medications immediately after cornea transplant and during recovery will help control infection, swelling, and pain.
Wear an eye patch. An eye patch might protect your eye as it heals post-surgery
Protect your eye from injury. Plan to take it easy post your cornea transplant, and slowly work your way up to your normal activities, including exercise. For the rest of your life, you’ll need to take extra precautions to avoid harming your eye.
Return for frequent follow-up exams. Go for regular eye exams in which your doctor looks for complications in the first year after surgery.
