World Class Cornea Treatments
The cornea is the transparent, dome-shaped tissue covering the front of the eye. Replacing the damaged or opaque cornea with a clear, healthy cornea from a donor is referred to as corneal transplant, corneal graft or Penetrating Keratoplasty (PK). There are many different types of Corneal transplants depending on the part of Cornea damaged. All types of Corneal transplants are performed routinely in our hospital. Of all issue transplants in a human body, corneal transplants are the most successful.
Keratoplasty / Corneal Transplant
A graft replaces central corneal tissue, damaged due to disease or injury, with healthy corneal tissue donated from a local eye bank. An unhealthy cornea affects your vision by scattering or distorting light and causing blurry or glary vision. A cornea transplant may be necessary to restore your functional vision.

Cornea transplants are performed routinely in our hospital n fact, of all tissue transplants, the most successful is a corneal transplant.
Are You a Cornea Transplant Candidate?
Corneal Transplant is done in various conditions:
- Hereditary factors or corneal failure from previous surgeries.
- Thinning of the cornea and irregular shape (such as with keratoconus).
- Chemical burns on the cornea or damage from an eye injury.
- Excessive swelling (edema) on the cornea.
- Corneal transplants are performed in order to protect the eye’s inner structures, relieve pain, and improve vision.
Tears are a combination of water for moisture, oils for lubrication, mucus for even spreading . These components are secreted by special glands. When there’s imbalance in this tear system, a person may experience dry eye.
How to recognize dry eye?
When tears do not adequately lubricate the eye, one may experience:
- Light insensitivity
- Gritty sensation
- Feeling of foreign body or dust in eye
- Blurring of vision
Treatment of dry eyes
Dry eyes cannot be cured but there are a number of steps that can be taken to treat them. Based on patient to patient ,management includes:
- Artificial lubricant eye drops and ointment
- Punctal occlusion: It is a procedure in which the channels through which tears flow out of the eyes are closed either temporarily or permanently.
Sometimes dry eye can be a result of medicine s the patient is already using or a manifestation of systemic diseases like rheumatoid arthritis. These conditions should be ruled out in the diagnosis of dry eye.
Its an allergic reaction on the surface of the eyes. Its a very common condition that occurs when any allergy causing substances comes in contact with your eyes. The allergic reaction sets in following contact of allergen with the ocular surface.
How to recognize allergic Red eye?
- Usually both the eyes are affected.
- The eyes a re itchy and the white of the eye looks red or pink.
- Feeling of burning sensation
- Tendency to rub the eyes frequently
- Watering of eyes
- Swelling of eye lids.
- The best treatment of allergic conjunctivitis is to avoid contact with allergy causing substance.
- If you use contact lens ,do not wear lenses until the symptoms have gone.
- Do not rub your eyes as it increases the inflammation.
Antihistaminic eye drops and mast cell stabilizer eye drops to keep symptoms at bay.
Keratoconus And C3R
Keratoconus is an eye condition where the clear front of the eye, the cornea, gets thin and bulges outward into a cone shape. This spoils the quality of the image projected into the eye, and the vision becomes progressively blurred. This usually begins in the teens or early twenties and affects mostly males Glasses may be sufficient in the early stages of keratoconus, but contact lenses are needed when the cornea becomes so misshapen that glasses are no longer effective in correcting vision. In some cases, the corneal shape becomes too distorted that contact lenses won’t fit. Also, scarring may develop, causing vision to become clouded. At this stage, a corneal transplant is usually needed.
C3-R is a non-surgical keratoconus treatment method that can stop keratoconus from progressing to the stage where contact lenses or corneal transplantation becomes necessary.
Corneal collagen crosslinking with riboflavin causes the formation of normal chemical links between the collagen protein strands in the cornea. This makes the cornea more rigid and can stop the keratoconus from progressing. The treatment may even cause the keratoconus to reverse to some extent.
Anyone with progressive keratoconus is potentially suitable. Patients with very advanced keratoconus or whose vision is already spoiled by scarring will usually not be good candidates for the procedure. The facility of C3R is available at our hospital.
What is corneal blindness?
Light passes through the transparent cornea to make an image for the person to see. Sometimes the transparent cornea becomes opaque, cloudy, or white and loses its transparency following trauma, infection, or other diseases. In such cases, no light is able to enter the eye and this condition is known as corneal blindness.
What is the need for eye donation?
Only 13,500 corneal transplants are being performed every year, while 30,000 new patients are added each year to the long list of 900,000 patients already waiting to be cured. Adequate number of corneal transplantations cannot be carried out due to lack of donor corneas. There are more than 80 Lakh deaths every year, but sadly the corneal donations do not exceed thirty thousand. There is till date no artificial cornea available which can replace the natural cornea .Hence the need for eye donation.
Contraindications for eye donation
Persons who are infected with, or have died from, AIDS, hepatitis B or C, rabies, and/ or septicemia cannot donate eyes.
What is the importance of consent for eye donation?
The consent of the next of kin is essential for removing the eye after the donor’s death. No financial transaction of any sort is allowed in the process of eye donation. , it is illegal to buy or sell human eyes, organs or tissues.
How quickly should corneas be removed after death?
Corneas should be removed preferably within an hour, but can be removed up to a maximum of 6-8 hours, of death.
What happens after eye donation?
Tests are carried out and the report is sent to the corneal surgeon. The eyes are used for a corneal transplantation within 72 hours, but with. Present day availability of special storage media the eyes can be stored for a longer time before being transplanted. The recipient is chosen from the eye banks waiting list and called for a corneal transplant.
