Cornea Clinic


A corneal transplantation is also called corneal grafting or keratoplasty. This sight-restoring procedure is normally reserved for situations when all other medication options have been consumed.

Common Corneal disorders

Some of the commonly seen corneal disorders are :

  • Corneal ulcer (bacterial/fungal/viral)
  • Corneal opacities
  • Keratoconus
  • Pterygium
  • Corneal dystrophy
  • Corneal degeneration
  • Bullous keratopathy (Post cataract surgery corneal edema)

Full-thickness corneal transplants

Full-thickness transplants (also called penetrating keratoplasty) is the most commonly performed corneal transplant procedure. If you suffer from keratoconus or corneal scarring and have exhausted all other forms of treatment, this procedure will most likely be recommended.
The cornea has five layers. Surgery involves cutting through all five corneal layers to remove the damaged or diseased section. The donor cornea, usually about the size of a small button, is then gently positioned onto the host bed and stitched into place. The stitches are removed at a later date.

Partial-thickness corneal transplants

If some of the corneal layers are undamaged or free from disease, a partial thickness corneal transplant may be advised. In this case, only the affected layers are removed. The surgeon does not cut through the entire thickness of the cornea. These layers are replaced with layers of healthy donor tissue.

The anterior lamellar procedure is called DALK and is indicated in severe advanced keratoconus and corneal scarring. The posterior lamellar procedures are DSEK, DMEK in which only endothelial layer is replaced. This is indicated in conditions like Bullous Keratopathy. There are various advantages of lamellar procedures like low risk of graft rejection and failure

C3R for Keratoconus

A novel procedure known as C3R (corneal collagen crosslinking with riboflavin) is done in patients of keratoconus to prevent disease progression and worsening. This is followed by prescribing RGP contact lenses 4-6 weeks later to improve quality of vision in such patients as spectacles are not suitable for most cases.

Pterygium excision with conjunctival autograft

Pterygium is a wing shaped encroachment of conjunctiva over the cornea mostly seen in men working outdoors. This is a very common condition which needs surgery as no medication can regress the growth.

The procedure of choice is pterygium excision with a conjunctival autografting which can either be sutured or glued over the defect to prevent recurrences.

Facilities Available

The cornea is the outermost transparent part of the eye through which light enters the eye and is refracted. There are various pathological conditions of cornea like ulcers, opacities, degenerations & dystrophies. Some of these diseases can be managed medically with eye drops while certain conditions require corneal surgery.  Keratoplasty is the procedure where the diseased cornea is replaced with a healthy donor cornea.

We at high tech eye care & laser center have various diagnostic equipment like photo slit lamp, corneal topography, pachymetry to diagnose pathologies at an early stage. We also offer various treatment modalities like C3R for Keratoconus, Sutureless grafting after pterygium excision etc.
