Cornea is the clear outer surface of the eye and is often referred to as watch glass. The cornea permits light to enter the eye & focus on the retina. When its clarity is compromised by infection or other diseases light transmission is reduced and may result in blindness also.

 Importance of the cornea for good vision :

The cornea is essential to good vision. For example, the cornea filters out some of the most damaging ultraviolet (UV) wavelengths in sunlight. Without this protection, the crystalline lens and the retina would be highly susceptible to injury from UV radiation.

If this "window" is curved too much, as is the case in some nearsighted people, faraway objects will appear blurry because distant light waves will refract imperfectly on the retina. If this "window" has imperfections or irregularities, as is the case in people with an astigmatism, light will refract unequally, causing a slight distortion of the visual image. But, if this "window" is of normal shape and curvature, light will refract with exquisite precision to the crystalline lens.

Problems affecting the cornea :

Refractive errors
Corneal Ulcer
Conjunctivitis
Pterygium
Corneal opacity
Injuries
Corneal Dystrophies
Keratoconus
 
Treatment :

Lasik
Special diagnostic and therapeutic care is laid at our Cornea Clinic at Susheel Eye Institute.
Autologous Limbal Steam Cell Transplantation with/without amniotic Membrane. Transplantation in cases of Moderate Limbal Steam Cell (LSC) Deficiencies/ grade 1-2 chemical burns/ Persistent Epithelial Defects (PEDs)/ Non-Healing Ulcers.
Corneal scrapings – diagnostic and therapeutic.
               
Newer Treatment Modalities like:

Intacs (Intra Cornea Rings); C3R/UVX have been introduced for mild to mod cases of KERATOCONUS aided with SPECIALISED KERATOCONUS LENS - ROSE K LENSES for better optical result post UVX.
Glue + BCL in case of micro corneal perforations.
Lamellar corneal tattooing for cosmetic purposes.

 Causes of corneal blindness :

Injuries to the eye
Birth Defects
Malnutrition
Infections
Chemical Burns
Congenital Disorders and Complications of Eye Surgery.

The cornea transplant is the surgical procedure, which replaces a disc-shaped segment of an impaired cornea with a similarly shaped piece of a healthy donor cornea.

 Surgical treatment :

Optical penetrating Keratoplasties (Pks)
Optical PK with IOL Implantations
Descement Stripping Endothelial Keratoplasties (DSEK)
Deep Anterior Lamellar Keratoplasties (DALK)
Therapeutic Keratoplasties (TPK)
Regrafting (PK/DSEK)
Tectonic PK
Cosmetic PK

 

What is an Eye Donation?
Donating eyes after the death of a person is called eye donation.

What is corneal blindness?
Cornea, the main focusing part , is the clear front surface of the eye. Like a window, it allows light to enter the eye. Vision could be markedly reduced or lost if the cornea becomes cloudy or scarred. This condition is known as corneal blindness.

What are the causes of corneal blindness?
Injuries to the eye, birth defects, malnutrition, infections, chemical burns, congenital disorders and complications of eye surgery.

What is a cornea transplant?
The cornea transplant is the surgical procedure, which replaces a disc-shaped segment of an impaired cornea with a similarly shaped piece of a healthy donor cornea.

Are there any age restrictions for eye donation?
Eye tissue from donors between the ages of 1 and 75 is potentially eligible to be used for transplantation. People over the age of 75 may still donate, but the tissue would be used for scientific research, medical education, and the advancement of medical technique.

Who can be an eye donor?
Anyone. Cataracts, poor eyesight and age do not prevent someone from becoming a donor. Prospective donors should indicate their intention on donor cards. Perhaps the most important single thing you can do is make your immediate near & dear ones aware of your wishes to make sure they are carried out.

Who cannot be an eye donor?
Persons with AIDS, Hepatitis B and C, Rabies, Septicaemia, Acute leukemia (Blood cancer), Tetanus, Cholera, and infectious diseases like Meningitis and Encephalitis cannot donate eyes.

Why should eyes be donated?
Donated human eyes and corneal tissue are necessary for the preservation and restoration of sight and are used for transplantation, research and education. Over 90 percent of all cornea transplant operations performed each year successfully restores vision to people suffering from corneal blindness.

How can I become a donor?
First and foremost, you need to ensure that your family and near and dear ones know about your intent to donate your eyes. Families may give consent for donation. It is most helpful if they know how you feel in advance. A donor card can serve as an indication to your family and the hospitals of your intention to be an eye donor.

If the death certificate from the physician is available, keep it ready.
   
Eye donation can be done only with the written consent of the next of kin in the presence of two witnesses.

 What happens after eye donation?

The donor's family receives a certificate of appreciation from the eye bank. The eyes are taken to the eye bank and evaluated by a trained eye bank staff.
   
Tests are carried out and the tissue is sent to the corneal surgeon.
   
The waiting list is referred and the recipient is called for corneal transplant.
   
Corneal transplant is performed.
   
Periodic follow-up of the recipient is done over time to ensure that the graft is successful.
