Cornea Transplant & Services

What is the 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 Diseases: An Overview

What are the disease conditions that affect the cornea?
Corneal disorders if severe make the cornea cloudy, scarred, and distorted, eventually leading to vision loss.
There are many corneal diseases:


Inflammation of the cornea which leads to redness, swelling and ulcer formation is known as keratitis. The most common cause of keratitis is contact lens-induced infection in urban India and vegetative injury in farmland, in rural India.

Dry eye

Dry eye is a common condition that occurs when tear production is limited by certain local, systemic and hormonal disorders. It leads to a constant redness, burning, foreign body sensation and intolerance to digital devices like computers & mobiles.

Corneal Dystrophies

Corneal dystrophies are the group of genetic conditions, which runs in a family, results from the deposition of material in a transparent cornea making it translucent to opaque. Corneal dystrophies with compromised corneal clarity lead to a drastic decrease in the quality of vision. Some of the most common corneal dystrophies are Epithelial basement membrane dystrophy, Fuchs corneal dystrophy & Macular corneal dystrophy.

Ocular Herpes

Also known as Herpes of the eye. The infection is caused by herpes simplex virus I (HSV I). Ocular herpes leads to painful blisters on the eyelids and inflammation of all the layers of the eye. It is notorious for relapses & recurrences if not treated appropriately.


Malnutrition leads to a deficiency of vital nutrients like Vitamin A, which is essential for maintaining the health of the ocular surface, the defense mechanism of the eye and hence the quality of vision. Nutritional deficiency results in unhealthy ocular surface, decreased ability to fight harmful pathogens and episodes of recurrent inflammations.

Congenital Diseases

Be it inadequate healthcare during pregnancy or a chance of fate, various congenital corneal conditions like corneal dystrophy, congenital glaucoma etc. play a major role in increasing the rate of cornea related blindness.


Eye trauma accounts for a considerable scale of corneal blindness every year around the world. Ocular trauma at the workplace is the most common factor which deserves attention and calls for better safety measures.


Trachoma, an eye infection of its kind, is one of the significant reasons for corneal scarring and has blinded millions of people so far. Apart from trachoma, other bacteria, fungi, and viruses lead their way up to blindness.

Traditional Medicines & Home Remedies

Self-medication measures like using honey, ginger juice, kajal, surma, etc. as eye drops and home remedies to treat the eye problems do more harm than good. Such practices might end up in disastrous complications and even vision loss.

Corneal Transplant Surgery


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.

Our surgeons discuss possible treatment options with the patient and decide on the choice of the corneal transplant procedure, depending on the disease entity.

Types of cornea transplant surgery available at Centre for Sight:

Penetrating Keratoplasty (PK)

Penetrating Keratoplasty is also known as full-thickness corneal transplant. It involves the replacement of the whole diseased cornea with the healthy corneal tissue.

Anterior Lamellar Keratoplasty (ALK, DALK)

Anterior Lamellar Keratoplasty is a type of partial-thickness corneal transplant surgery that is done to replace the anterior diseased corneal tissue with healthy and transparent donor tissue. This corneal transplant surgery aims to preserve the back part of the cornea.

Endothelial Keratoplasty (DSAEK, DMEK, PDEK):

Endothelial Keratoplasty is another type of partial-thickness corneal transplant surgery which addresses posterior corneal pathologies. Part of the posterior diseased cornea is replaced with healthy donor posterior cornea. These are highly specialized surgeries, in certain conditions like Fuchs corneal dystrophy, where only the endothelial cell layer (the innermost layer of the cornea responsible for maintaining corneal transparency) is non-functional, only the endothelial cell layer will be transplanted. This means replacing only diseased corneal layers and leaving behind an intact anterior (front part) cornea which leads to faster visual rehabilitation.

This procedure reduces the risk of rejection and obviates the need for sutures.


At Centre for Sight, we perform corneal transplant as a daycare procedure with the flexibility of discharging the patient on the same day of the surgery with proper precautions and treatment explained. Post-surgery patients are under the regular care of trained cornea professionals.

Centre for Sight Eye Bank encourages eye donations in India by bringing about a change in the mindsets of the people. With the support of our patrons and patients, our eye banks in India seek to bring light into the lives of those who have corneal blindness.

What Do We Offer For Corneal Ulcer Treatment?

What is a corneal ulcer?

A corneal ulcer is an open sore that develops on the cornea. Common causes of corneal ulcers are viral, fungal, bacterial & parasitic infection.

Corneal Ulcer Treatment

At Centre for Sight, we perform comprehensive eye examinations to evaluate the cause of corneal ulcer and design appropriate treatment.

Corneal Ulcer Evaluation:
  • Visual acuity test

    As a part of the corneal ulcer evaluation, visual acuity is checked on every visit. This allows our expert to assess the present status and follow the progression of the disease.

  • Slit-lamp Biomicroscopy:

    Our specialists evaluate every patient on Slit-lamp, which is a highly specialized device and magnifies the area of interest.

  • Microbiological Test:

    It is of utmost importance to know the cause of the corneal ulcer. As a part of an assessment protocol, cornea specialists scrape the part of the ulcer and send it to the laboratory for evaluation. The idea behind this test is an in-depth analysis of causative organisms and sensitivity to assess testing for appropriate drug therapy.

Medical Management of Corneal Ulcer

After identifying the microorganism responsible for the eye infection, our specialists start the treatment according to the drug sensitivity report.

Surgical Management of Corneal Ulcer

In case of failure of conservative & medical management, the surgical treatment ensures eye integrity and it is the mainstay of the treatment in case of impending perforation. Surgical treatment includes Full thickness or partial thickness corneal transplant.

What We Offer For Keratoconus

Keratoconus is a progressive degenerative disorder of the cornea. This condition results in forward conical bulging of the cornea and hence distort the shape which leads to a poor visual outcome. This cone-shaped cornea prevents light from focusing on the retina and results in irregular astigmatism with compromised visual acuity. Advanced cases with extreme thinning or scarring require corneal transplantation.

Keratoconus Corneal Transplantation

Centre for Sight offers the entire spectrum of the treatment modalities from Corneal collagen crosslinking with riboflavin, intrastromal ring segments, Implantable Collamer Lenses (ICL) to corneal transplant.

We are well equipped with the advanced corneal evaluation devices like Corneal tomography systems (Pentacam & Orbscan), Corvis to assess corneal biomechanics & strength which help in the early detection and monitoring of the disease.

What happens Post-Keratoconus Corneal Transplantation?

In Keratoconus, a corneal transplant is performed to restore vision when other modalities like eyeglasses, contact lenses or Corneal collagen crosslinking fail. Corneal transplantation is the daycare procedure, a patient gets discharged on the same day of the surgery. Precautions and treatment plan will be explained before discharging a patient. Since healing takes a few weeks to a month, the follow-up plan is customized for every patient and they remain under the strict care of the cornea surgeon.

Here are some of the most common ways by which your child can get a corneal abrasion:
● Injury with fingernails, toys, and other sharp & pointed objects like a pencil.
● External irritants like dirt, pebbles, insects, wood shavings, hay, etc. can easily cause corneal abrasions.
● Chemical pollutants and fumes in the air are another cause for corneal abrasions.
